Inheritance diagram for PV::RequireAllZeroActivityProbe:

BaseProbe Parameters
List of parameters for the BaseProbe class
virtual void	ioParam_message (enum ParamsIOFlag ioFlag)
	message: A string parameter that is typically included in the lines output by the outputState method

virtual void	ioParam_textOutputFlag (enum ParamsIOFlag ioFlag)
	textOutputFlag: A boolean parameter that sets whether to generate an output file. Defaults to true.

virtual void	ioParam_probeOutputFile (enum ParamsIOFlag ioFlag)
	probeOutputFile: If textOutputFlag is true, probeOutputFile specifies the name of the file that the outputState method writes to. If blank, the output is sent to the output stream.

virtual void	ioParam_triggerFlag (enum ParamsIOFlag ioFlag)
	triggerFlag: If false, the needUpdate method always returns true, so that outputState is called every timestep. If true, the needUpdate method uses triggerLayerName and triggerOffset to determine if the probe should be triggered.

virtual void	ioParam_triggerLayerName (enum ParamsIOFlag ioFlag)
	triggerLayerName: If triggerFlag is true, triggerLayerName specifies the layer to check for triggering.

virtual void	ioParam_triggerOffset (enum ParamsIOFlag ioFlag)
	triggerOffset: If triggerFlag is true, triggerOffset specifies the time interval before the triggerLayer's nextUpdate time that needUpdate() returns true.

virtual void	ioParam_energyProbe (enum ParamsIOFlag ioFlag)
	energyProbe: If nonblank, specifies the name of a ColumnEnergyProbe that this probe contributes an energy term to.

virtual void	ioParam_coefficient (enum ParamsIOFlag ioFlag)
	coefficient: If energyProbe is set, the coefficient parameter specifies that ColumnEnergyProbe multiplies the result of this probe's getValues() method by coefficient when computing the error. More...

LayerProbe Parameters
List of parameters for the LayerProbe class
virtual void	ioParam_targetName (enum ParamsIOFlag ioFlag) override
	targetName: the name of the layer to attach the probe to. In LayerProbes, targetLayer can be used in the params file instead of targetName. LayerProbe looks for targetLayer first and then targetName.

RequireAllZeroActivityProbe Parameters
List of parameters needed from the RequireAllZeroActivityProbe class
virtual void	ioParam_exitOnFailure (enum ParamsIOFlag ioFlag)
	exitOnFailure: If true, will error out if a nonzero value is encountered. Default is true. To control when the error is thrown, see immediateExitOnFailure. If set to false, the presense of a nonzero value can still be retrieved with the getNonzeroFound() method, and the earliest time at which a nonzero value appears is available through getNonzeroTime().

virtual void	ioParam_immediateExitOnFailure (enum ParamsIOFlag ioFlag)
	immediateExitOnFailure: determines when finding a nonzero value causes an exit with an error. If true, outputState will exit on the timestep a nonzero value is detected. If false, will not error out until the probe is deleted (which usually happens when the HyPerCol is deleted). Parameter is only read if exitOnFailure is true. Default is true.

virtual void PV::StatsProbe::calcValues ( double timevalue )

inlineoverrideprotectedvirtualinherited

Implements calcValues() for StatsProbe to always fail (getValues and getValue methods should not be used).

Implements PV::BaseProbe.

Definition at line 55 of file StatsProbe.hpp.

Response::Status PV::LayerProbe::communicateInitInfo ( std::shared_ptr< CommunicateInitInfoMessage const > message )

overridevirtualinherited

Called by HyPerCol::run. It calls BaseProbe::communicateInitInfo, then checks that the targetLayer/targetName parameter refers to a HyPerLayer in the parent HyPerCol, and then calls the layer's insertProbe method.

Implements PV::BaseProbe.

Reimplemented in PV::AbstractNormProbe, PV::FirmThresholdCostFnProbe, PV::FirmThresholdCostFnLCAProbe, PV::L0NormLCAProbe, PV::L1NormLCAProbe, and PV::PointProbe.

Definition at line 54 of file LayerProbe.cpp.

double PV::BaseProbe::getCoefficient ( )

inlineinherited

Returns the coefficient if the energy probe is set.

Definition at line 95 of file BaseProbe.hpp.

bool PV::BaseObject::getDataStructuresAllocatedFlag ( ) const

inlineinherited

Get-method for mDataStructuresAllocatedFlag, which is false on initialization and then becomes true once setDataStructuresAllocatedFlag() is called.

Definition at line 102 of file BaseObject.hpp.

char const* PV::BaseProbe::getEnergyProbe ( )

inlineinherited

Returns the name of the energy probe the probe is attached to (null if not attached to an energy probe)

Definition at line 90 of file BaseProbe.hpp.

bool PV::BaseObject::getInitialValuesSetFlag ( ) const

inlineinherited

Get-method for mInitialValuesSetFlag, which is false on initialization and then becomes true once setInitialValuesSetFlag() is called.

Definition at line 108 of file BaseObject.hpp.

bool PV::BaseObject::getInitInfoCommunicatedFlag ( ) const

inlineinherited

Get-method for mInitInfoCommunicatedFlag, which is false on initialization and then becomes true once setInitInfoCommunicatedFlag() is called.

Definition at line 95 of file BaseObject.hpp.

double PV::BaseProbe::getLastUpdateTime ( )

inlineinherited

Returns the time that calcValues was last called. BaseProbe updates the last update time in getValues() and getValue(), based on the result of needRecalc.

Definition at line 102 of file BaseProbe.hpp.

const char* PV::BaseProbe::getMessage ( )

inlineprotectedinherited

Returns a pointer to the message parameter.

Definition at line 280 of file BaseProbe.hpp.

int PV::BaseProbe::getNumValues ( )

inlineinherited

Returns the number of value indices the probe can compute (typically the value of the parent HyPerCol's nBatch parameter). BaseProbe::getNumValues() returns the parent HyPerCol's getNBatch(), which can be overridden. Probes derived from BaseProbe can set numValues to zero or a negative number to indicate that getValues() and getNumValues() are not fully implemented for that probe.

Definition at line 61 of file BaseProbe.hpp.

char const* PV::BaseProbe::getProbeOutputFilename ( )

inlineprotectedinherited

Returns the probeOutputFilename parameter

Definition at line 314 of file BaseProbe.hpp.

const char* PV::BaseProbe::getTargetName ( )

inlineinherited

Returns the name of the targetName parameter for this probe. LayerProbe uses targetName to specify the layer to attach to; BaseConnectionProbe uses it to specify the connection to attach to.

Definition at line 83 of file BaseProbe.hpp.

bool PV::BaseProbe::getTextOutputFlag ( ) const

inlineprotectedinherited

Returns the value of the textOutputFlag parameter

Definition at line 324 of file BaseProbe.hpp.

double PV::BaseProbe::getValue	(	double	timevalue,
		int	index
	)

inherited

getValue() is meant for situations where the caller needs one value that would be returned by getValues(), not the whole buffer. getValue() returns a signaling NaN if index is out of bounds. If index is valid, getValue() calls calcValues() if needRecalc() returns true, and then returns probeValues[index]. Derived classes should not override or hide this method. Instead, they should override calcValues.

Definition at line 346 of file BaseProbe.cpp.

void PV::BaseProbe::getValues	(	double	timevalue,
		double *	valuesVector
	)

inherited

getValues(double timevalue, double * values) sets the buffer 'values' with the probe's calculated values. It assumes that the values buffer is large enough to hold getNumValues() double-precision values. If 'values' is NULL, the values are still updated internally if needed, but those values are not returned. Internally, getValues() calls calcValues() if needRecalc() is true. It then copies the probeValues buffer to the input argument buffer 'values'. Derived classes should not override or hide this method. Instead, they should override calcValues.

Definition at line 336 of file BaseProbe.cpp.

void PV::BaseProbe::getValues	(	double	timevalue,
		std::vector< double > *	valuesVector
	)

inherited

getValues(double timevalue, vector<double> * valuesVector) is a wrapper around getValues(double, double *) that uses C++ vectors. It resizes valuesVector to size getNumValues() and then fills the vector with the values returned by getValues.

Definition at line 341 of file BaseProbe.cpp.

void PV::BaseProbe::getValues ( double timevalue )

protectedinherited

If needRecalc() returns true, getValues(double) updates the probeValues buffer (by calling calcValues) and sets lastUpdateTime to the timevalue input argument.

Definition at line 329 of file BaseProbe.cpp.

double* PV::BaseProbe::getValuesBuffer ( )

inlineprotectedinherited

Returns a pointer to the buffer containing the probeValues.

Definition at line 319 of file BaseProbe.hpp.

int PV::BaseProbe::initMessage ( const char * msg )

protectedvirtualinherited

The method called by BaseProbe::initialize() to set the message used by the probe's outputState method.

Definition at line 282 of file BaseProbe.cpp.

void PV::StatsProbe::initNumValues ( )

overrideprotectedvirtualinherited

StatsProbe sets numValues to -1, indicating that the getValues and getValue methods don't work. StatsProbe is an old probe that might be deprecated in favor of more getValues-friendly probes.

Reimplemented from PV::BaseProbe.

Definition at line 167 of file StatsProbe.cpp.

void PV::BaseProbe::initOutputStreams	(	const char *	filename,
		Checkpointer *	checkpointer
	)

protectedvirtualinherited

Called by registerData. If the MPIBlock row index and column index are zero, this method sets a vector of PrintStreams whose size is the local batch width. If probeOutputFile is being used, the elements of the vector are FileStreams with filenames based on probeOutputFile: the global batch index will be inserted in the probeOutputFile before the extension (or at the end if there is no extension). If the MPIBlock row and column indices are not both zero, the vector of PrintStreams will be empty - these processes should communicate with the row=0,column=0 as needed.

Reimplemented in PV::ColProbe, PV::BaseConnectionProbe, and PV::PointProbe.

Definition at line 174 of file BaseProbe.cpp.

void PV::BaseProbe::ioParam_coefficient ( enum ParamsIOFlag ioFlag )

protectedvirtualinherited

coefficient: If energyProbe is set, the coefficient parameter specifies that ColumnEnergyProbe multiplies the result of this probe's getValues() method by coefficient when computing the error.

Note that coefficient does not affect the value returned by the getValue() or getValues() method.

Reimplemented in PV::FirmThresholdCostFnLCAProbe, PV::L0NormLCAProbe, and PV::L1NormLCAProbe.

Definition at line 106 of file BaseProbe.cpp.

void PV::BaseObject::ioParams	(	enum ParamsIOFlag	ioFlag,
		bool	printHeader,
		bool	printFooter
	)

inherited

Method for reading or writing the params from group in the parent HyPerCol's parameters. The group from params is selected using the name of the connection.

If ioFlag is set to write, the printHeader and printFooter flags control whether a header and footer for the parameter group is produces. These flags are set to true for layers, connections, and probes; and set to false for weight initializers and normalizers. If ioFlag is set to read, the printHeader and printFooter flags are ignored.

Note that ioParams is not virtual. To add parameters in a derived class, override ioParamFillGroup.

Definition at line 74 of file BaseObject.cpp.

int PV::RequireAllZeroActivityProbe::ioParamsFillGroup ( enum ParamsIOFlag ioFlag )

overrideprotectedvirtual

The virtual method for reading parameters from the parent HyPerCol's parameters, and writing to the output params file.

Derived classes with additional parameters typically override ioParamsFillGroup to call the base class's ioParamsFillGroup method and then call ioParam_[parametername] for each of their parameters. The ioParam_[parametername] methods should call the parent HyPerCol's ioParamValue() and related methods, to ensure that all parameters that get read also get written to the outputParams-generated file.

Reimplemented from PV::StatsProbe.

Definition at line 26 of file RequireAllZeroActivityProbe.cpp.

bool PV::BaseObject::isUsingGPU ( ) const

inlineinherited

Returns true if the object requires the GPU; false otherwise. HyPerCol will not initialize the GPU unless one of the objects in its hierarchy returns true

Definition at line 116 of file BaseObject.hpp.

bool PV::BaseProbe::isWritingToFile ( ) const

inlineprotectedinherited

Returns true if a probeOutputFile is being used. Otherwise, returns false (indicating output is going to getOutputStream().

Definition at line 330 of file BaseProbe.hpp.

char const * PV::BaseObject::lookupKeyword ( ) const

inherited

Look up the keyword of the params group with the same name as the object.

Definition at line 42 of file BaseObject.cpp.

virtual bool PV::StatsProbe::needRecalc ( double timevalue )

inlineoverrideprotectedvirtualinherited

Implements needRecalc() for StatsProbe to always return false (getValues and getValue methods should not be used).

Reimplemented from PV::LayerProbe.

Definition at line 48 of file StatsProbe.hpp.

bool PV::BaseProbe::needUpdate	(	double	time,
		double	dt
	)

protectedvirtualinherited

If there is a triggering layer, needUpdate returns true when the triggering layer's nextUpdateTime, modified by the probe's triggerOffset parameter, occurs; otherwise false. If there is not a triggering layer, needUpdate always returns true. This behavior can be overridden if a probe uses some criterion other than triggering to choose when output its state.

Reimplemented in PV::AdaptiveTimeScaleProbe.

Definition at line 313 of file BaseProbe.cpp.

PrintStream& PV::BaseProbe::output ( int b )

inlineprotectedinherited

Returns a reference to the PrintStream for the given batch element

Definition at line 291 of file BaseProbe.hpp.

Response::Status PV::RequireAllZeroActivityProbe::outputState ( double timef )

overridevirtual

A pure virtual method for writing output to the output file.

Reimplemented from PV::StatsProbe.

Definition at line 56 of file RequireAllZeroActivityProbe.cpp.

Response::Status PV::BaseProbe::outputStateWrapper	(	double	timef,
		double	dt
	)

virtualinherited

The public interface for calling the outputState method. BaseConnection::outputStateWrapper calls outputState() if needUpdate() returns true. This behavior is intended to be general, but the method can be overridden if needed.

Definition at line 358 of file BaseProbe.cpp.

void PV::BaseObject::readParams ( )

inlineinherited

A method that reads the parameters for the group whose name matches the name of the object. It, along with writeParams(), is a wrapper around ioParams, so that readParams and writeParams automatically run through the same parameters in the same order.

Definition at line 62 of file BaseObject.hpp.

double PV::LayerProbe::referenceUpdateTime ( ) const

overrideprotectedvirtualinherited

Implements the referenceUpdateTime method. Returns the last update time of the target layer.

Implements PV::BaseProbe.

Definition at line 81 of file LayerProbe.cpp.

Response::Status PV::StatsProbe::registerData ( Checkpointer * checkpointer )

overrideprotectedvirtualinherited

Called during HyPerCol::run, during the allocateDataStructures stage. BaseProbe::allocateDataStructures sets up the output stream. Derived classes that override this method should make sure to call this method in their own allocateDataStructures methods.

Reimplemented from PV::BaseProbe.

Definition at line 169 of file StatsProbe.cpp.

void PV::BaseObject::setDataStructuresAllocatedFlag ( )

inlineprotectedinherited

This method sets mDataStructuresAllocatedFlag to true.

Definition at line 175 of file BaseObject.hpp.

void PV::BaseObject::setInitialValuesSetFlag ( )

inlineprotectedinherited

This method sets the flag returned by getInitialValuesSetFlag to true.

Definition at line 180 of file BaseObject.hpp.

void PV::BaseObject::setInitInfoCommunicatedFlag ( )

inlineprotectedinherited

This method sets mInitInfoCommunicatedFlag to true.

Definition at line 170 of file BaseObject.hpp.

void PV::BaseProbe::setNumValues ( int n )

protectedinherited

Sets the numValues member variable (returned by getNumValues()) and reallocates the probeValues member variable to hold numValues double-precision values. If the reallocation fails, the probeValues buffer is left unchanged, errno is set (by a realloc() call), and PV_FAILURE is returned. Otherwise, PV_SUCCESS is returned.

Definition at line 221 of file BaseProbe.cpp.

void PV::BaseObject::writeParams ( )

inlineinherited

A method that writes the parameters for the group whose name matches the name of the object. It, along with readParams(), is a wrapper around ioParams, so that readParams and writeParams automatically run through the same parameters in the same order.
