Member Function Documentation

◆ compressAndClear()

virtual bool Arcane::IDataInternal::compressAndClear ( DataCompressionBuffer & buf )

inlinevirtual

Compresses the data and frees the associated memory.

Compresses the data and fills buf with the compressed information. Then it frees the associated memory. The instance will no longer be usable until decompressAndFill() has been called.

Return values

true	if compression occurred.
false	if the instance does not support compression. In this case it remains usable.

Warning: Calling this method modifies the underlying container. If this data is associated with a variable, IVariable::syncReferences() must be called.

Reimplemented in Arcane::Array2DataT< DataType >::Impl, and Arcane::ArrayDataT< DataType >::Impl.

Definition at line 101 of file IDataInternal.h.

◆ computeHash()

virtual void Arcane::IDataInternal::computeHash ( DataHashInfo & hash_info )

pure virtual

Calculates the hash of the data.

Outputs the version and value into hash_info.m_version and hash_info.m_value.

Implemented in Arcane::Array2DataT< DataType >::Impl, Arcane::ArrayDataT< DataType >::Impl, Arcane::NumArrayDataT< DataType, RankValue >::Internal, Arcane::ScalarDataT< DataType >::Internal, Arcane::StringArrayData::Impl, and Arcane::StringScalarData::Internal.

◆ decompressAndFill()

virtual bool Arcane::IDataInternal::decompressAndFill ( DataCompressionBuffer & buf )

inlinevirtual

Decompresses the data and fills the data values.

Decompresses the data from buf and fills the values of this instance with the decompressed information.

Return values

true	if decompression occurred.
false	if no decompression occurred because the instance does not support it.

Warning: Calling this method modifies the underlying container. If this data is associated with a variable, IVariable::syncReferences() must be called.

Reimplemented in Arcane::Array2DataT< DataType >::Impl, and Arcane::ArrayDataT< DataType >::Impl.
