Additional Inherited Members
Static Public Member Functions inherited from Fiber::FiberIO::HDF5::PrecisionTransformation
static bool	readPossiblyConvertedData (RefPtr< MemBase > &NewData, CreativeArrayBase &theCreator)
	Function is similar to CreativeArrayBase::create() but more efficient than raw HDF5 in case data need to be converted from float to double precision upon reading.
static bool	possiblyShiftData (RefPtr< MemBase > &NewData, CreativeArrayBase &theCreator)
static std::pair< bool, hid_t >	getFileType (const StorageTransformations::FilterSettings &FS, hid_t Mem_type_hid, const Fiber::Field &theField, F5Path *myPath)
	Determine whether that specific field thing shall be written in single precision.
static void	adjustFileWriteInformation (const StorageTransformations::FilterSettings &FS, CreativeArrayBase &FieldFragmentAttributes, Attributes &OverrideStorageAttributes, AttributeSet_t &DontSaveAttributeSet, RefPtr< ChunkBase > &Mb, bool WriteDoubleTypeInSinglePrecision, bool Write_Shifted_Single_Precision_Range)
	Modify the information that will be written to the file.
