Member Function Documentation

◆ _setHashId()

void Arcane::VariablePrivate::_setHashId ( )

inlineprivate

Definition at line 180 of file Variable.cc.

◆ changeAllocator()

void Arcane::VariablePrivate::changeAllocator ( const MemoryAllocationOptions & alloc_info )

overridevirtual

Changes the variable's allocator.

Currently valid only for 1D variables. Does nothing for others.

Warning: For experimental use only.

Implements Arcane::IVariableInternal.

Definition at line 1486 of file Variable.cc.

References Arcane::INumericDataInternal::changeAllocator(), m_data, and m_variable.

Here is the call graph for this function:

◆ compareVariable()

VariableComparerResults Arcane::VariablePrivate::compareVariable ( const VariableComparerArgs & compare_args )

overridevirtual

Applies the comparison method specified by compare_args.

Implements Arcane::IVariableInternal.

Definition at line 1508 of file Variable.cc.

References m_variable.

◆ computeComparisonHashCollective()

String Arcane::VariablePrivate::computeComparisonHashCollective	(	IHashAlgorithm *	hash_algo,
		IData *	sorted_data )

overridevirtual

Calculates the comparison hash for the variable.

sorted_data must be sorted according to uniqueId() and also by rank of the IParallelMng associated with the variable.

This method is collective, but only the master rank (the one for which IParallelMng::isMasterIO() is true) returns a valid hash. The others return a null string.

It also returns a null string if the data is not numeric (if sorted_data->_commonInternal()->numericData()==nullptr) or if the variable is not associated with a mesh entity.

Implements Arcane::IVariableInternal.

Here is the call graph for this function:

◆ replicaParallelMng()

IParallelMng * Arcane::VariablePrivate::replicaParallelMng ( ) const

virtual

Returns the IParallelMng of the mesh replica associated with the variable.

Returns nullptr if there is no replication.

Implements Arcane::IVariableInternal.

Definition at line 1517 of file Variable.cc.

References Arcane::IParallelReplication::hasReplication(), m_variable, Arcane::IParallelReplication::replicaParallelMng(), and Arcane::IParallelMng::replication().

Here is the call graph for this function:

◆ resize()

void Arcane::VariablePrivate::resize ( const VariableResizeArgs & resize_args )

overridevirtual

Resizes the variable by adding additional capacity.

Implements Arcane::IVariableInternal.

Definition at line 1499 of file Variable.cc.

References m_variable.

◆ serializeHashId()

void Arcane::VariablePrivate::serializeHashId ( ISerializer * sbuf )

inline

Serializes the hashid.

During deserialization, verifies that the hashid is correct and throws an exception if not.
