◆ changeAllocator()

virtual void Arcane::IVariableInternal::changeAllocator ( const MemoryAllocationOptions & alloc_info )

pure virtual

Changes the variable's allocator.

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

Warning: For experimental use only.

Implemented in Arcane::VariablePrivate.

◆ compareVariable()

virtual VariableComparerResults Arcane::IVariableInternal::compareVariable ( const VariableComparerArgs & compare_args )

pure virtual

Applies the comparison method specified by compare_args.

Implemented in Arcane::VariablePrivate.

Referenced by Arcane::VariableComparer::apply().

Here is the caller graph for this function:

◆ computeComparisonHashCollective()

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

pure virtual

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.

Implemented in Arcane::VariablePrivate.
