Detailed Description

A component to contain the x-by-y-by-f dimensions of a HyPerConn's or PoolingConn's patch size. The dimensions are read from the parameters nxp, nyp, and nfp. They are retrieved using the getPatchSizeX(), getPatchSizeY(), and getPatchSizeF() methods.

Member Function Documentation

int PV::PatchSize::calcPostPatchSize ( int  prePatchSize,
int  numNeuronsPre,
int  numNeuronsPost 
)
static

Calculates the patch size from the postsynaptic perspective, given the patch size from the presynaptic perspective and the PVLayerLoc structs for the pre- and post-synaptic layers.

If numNeuronsPre == numNeuronsPost, the return value is prePatchSize.

If numNeuronsPre > numNeuronsPost, numNeuronsPre must be an integer multiple of numNeuronsPost. The return value is prePatchSize * (numNeuronsPre / numNeuronsPost);

If numNeuronsPre < numNeuronsPost, numNeuronsPost must be an integer multiple of numNeuronsPre, and prePatchSize must be in integer multiple of their quotient. The return value is the prePatchSize / (numNeuronsPost / numNeuronsPre).

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

If nfp was set to a negative number in params, set it here to the postsynaptic layer's nf.

If nfp is positive in params, it is a fatal error for nfp and post->nf to have different values. It is also a fatal error if there is no ConnectionData component, or more than one, in the CommunicateInitInfo message.

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::PatchSize::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.

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.

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.

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.

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::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.
