Constructor & Destructor Documentation

Primer

(

)

[inline]

Reverse lookup for locating a tag for a given UL.

Member Function Documentation

UInt32 ReadValue	(	const UInt8 *	Buffer,
		UInt32	Size
	)

Read the primer from a buffer.

Returns:

Number of bytes read

UInt32 WritePrimer

(

DataChunkPtr &

Buffer

)

Write this primer to a memory buffer.

The primer will be appended to the DataChunk

Tag Lookup	(	ULPtr	ItemUL,
		Tag	TryTag = 0
	)

Determine the tag to use for a given UL.

If the UL has not yet been used the correct static or dynamic tag will be determined and added to the primer

Returns:

The tag to use, or 0 if no more dynamic tags available

Out of dynamic tags!

Tag StaticLookup	(	ULPtr	ItemUL,
		Tag	TryTag = 0
	)			[static]

Determine the tag to use for a given UL - when no primer is availabe.

std::pair<iterator, bool> insert

(

value_type

Val

)

[inline]

Insert a new child type.
