◆ _checkHashFunction()

void Arcane::VariableIOReaderMng::_checkHashFunction ( const VariableMetaDataList & vmd_list )

private

Checks hash function values.

Checks for each variable that its value is correct by calculating its hash function and comparing it to the value in the protection. If a variable has a different value, it is written to the listing directory at the same level as the logs.

◆ _readMetaData()

void Arcane::VariableIOReaderMng::_readMetaData	(	VariableMetaDataList &	vmd_list,
		Span< const Byte >	bytes )

private

Reading metadata.

Assuming that meta_data is a valid XML file, it iterates through all the variables it contains and creates a reference to each one if they do not already exist.

If necessary, for each variable present in the metadata, it creates it if it does not already exist. Furthermore, it saves the name to ensure that the value of this variable will be read correctly.
