Detailed Description

Deferred creation of MemBase objects from an HDF5 file.

Constructor & Destructor Documentation

HDF5CreatorBase()

Fiber::HDF5CreatorBase::HDF5CreatorBase	(	const RefPtr< LoaderProgress > &	BLP,
		const F5Fragment &	HC,
		const DynamicSize &	theSize,
		const RefPtr< MemBase > &	Data,

Construct a HDF5 creator for reading.

Indicate that the data managed here are already saved, and their "last saved" time is identical to the construction time of this Creator.
