Member Function Documentation

int PV::NormalizeBase::addConnToList ( HyPerConn newConn)

Appends the indicated connection to the list of connections for this normalizer

Definition at line 237 of file NormalizeBase.cpp.

int PV::NormalizeBase::communicateInitInfo ( CommunicateInitInfoMessage const *  message)

Called by HyPerConn::communicateInitInfo this virtual method is where settings that depend on other objects take place. In particular, NormalizeGroup calls its group head's addConnToList method from NormalizeGroup::communicateInitInfo method.

Reimplemented from PV::BaseObject.

Reimplemented in PV::NormalizeGroup.

Definition at line 88 of file NormalizeBase.cpp.

bool PV::BaseObject::getDataStructuresAllocatedFlag ( )

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

Definition at line 65 of file BaseObject.hpp.

bool PV::BaseObject::getInitialValuesSetFlag ( )

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

Definition at line 71 of file BaseObject.hpp.

bool PV::BaseObject::getInitInfoCommunicatedFlag ( )

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

Definition at line 58 of file BaseObject.hpp.

bool PV::BaseObject::isUsingGPU ( ) const

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 79 of file BaseObject.hpp.

int PV::NormalizeBase::normalizeWeightsWrapper ( )

The public interface for normalizing weights. If normalizeOnInitialize is true and the simulation time is startTime(), or if normalizeOnWeightUpdate is true and the simulation time is the conn's lastUpdateTime, it calls the (virtual protected) method normalizeWeights

Definition at line 95 of file NormalizeBase.cpp.

void PV::BaseObject::setDataStructuresAllocatedFlag ( )

This method sets mDataStructuresAllocatedFlag to true.

Definition at line 111 of file BaseObject.hpp.

void PV::BaseObject::setInitialValuesSetFlag ( )

This method sets the flag returned by getInitialValuesSetFlag to true.

Definition at line 116 of file BaseObject.hpp.

void PV::BaseObject::setInitInfoCommunicatedFlag ( )

This method sets mInitInfoCommunicatedFlag to true.

Definition at line 106 of file BaseObject.hpp.
