Detailed Description

Attribute Interface for accessing generic blob data.

This attribute interface allows access to blob data on an attribute. This is provided automatically if you inherit from GA_ATIBlob.

Methods used by the BlobBuffer methods to add an unreferenced blob to the attribute.

virtual void GA_AIFBlobArray::compactStorage ( GA_Attribute * attrib ) const

pure virtual

Compact the storage by removing empty indexes.

virtual void GA_AIFBlobArray::delBlobReference	(	GA_Attribute *	attrib,
		GA_BlobIndex	handle
	)		const

protectedpure virtual

virtual void GA_AIFBlobArray::getBlob	(	const GA_Attribute *	attrib,
		UT_Array< GA_BlobRef > &	blobs,
		GA_Offset	offset
	)		const

pure virtual

Get the blob data associated with the tuple index of the given element.

virtual GA_Size GA_AIFBlobArray::getBlobCount ( const GA_Attribute * attrib ) const

pure virtual

Return the total number of unique blobs stored in the attribute.

virtual void GA_AIFBlobArray::getBlobIndex	(	const GA_Attribute *	atr,
		UT_Array< GA_BlobIndex > &	indices,
		GA_Offset	offset
	)		const

pure virtual

Get the integer identifier for the blob associated with the tuple index of the given element. An element with no blob data will have an index less than 0.

virtual GA_BlobRef GA_AIFBlobArray::lookupBlob	(	const GA_Attribute *	attrib,
		GA_BlobIndex	handle
	)		const

pure virtual

Given a blob integer identifier, return a handle to the actual blob data.

virtual GA_BlobRef GA_AIFBlobArray::lookupOrderedBlob	(	const GA_Attribute *	attrib,
		exint	index
	)		const

pure virtual

Blob handles (GA_BlobIndex) may not be contiguous. This may be an expensive operation.

virtual bool GA_AIFBlobArray::replaceBlob	(	GA_Attribute *	attrib,
		GA_BlobIndex	handle,
		const GA_BlobRef &	new_blob
	)		const

pure virtual

Replace the value of the blob at the given index with a new value. Implementors should be careful to check whether the new_blob exists (i.e. renaming an existing blob to another existing blob). All blobs which reference the original handle will now reference the new blob.

virtual bool GA_AIFBlobArray::setBlob	(	GA_Attribute *	attrib,
		const UT_Array< GA_BlobRef > &	blobs,
		GA_Offset	offset
	)		const

pure virtual

Store a blob on the given element.
