Detailed Description

Attribute type implementation to store blind data per element.

This attribute type allocates a chunk of data per element (point, vertex or detail). The data is typeless. Users can write any data to this

Creation options may contain: "blinddata:size" - The initial size of the attribute (default 0) "blinddata:align" - The initial alignment (default sizeof(void *)) "blinddata:copy" - Copy data from element to element (default false)

void GA_ATIBlindData::copyNonStorageMetadata ( const GA_Attribute * that )

inlineoverridevirtual

In the case that we're copying from an attribute whose storage type matches this exactly, this function copies the metadata not associated with the storage, e.g. myOptions, excluding the name and the data ID.

Reimplemented from GA_Attribute.

Definition at line 211 of file GA_ATIBlindData.h.

void GA_ATIBlindData::countMemory	(	UT_MemoryCounter &	counter,
		bool	inclusive
	)		const

overridevirtual

Count memory usage using a UT_MemoryCounter in order to count shared memory correctly. If inclusive is true, the size of this object is counted, else only memory owned by this object is counted. If this is pointed to by the calling object, inclusive should be true. If this is contained in the calling object, inclusive should be false. (Its memory was already counted in the size of the calling object.)

NOTE: If you're implementing this in a direct subclass of GA_Attribute, call getBaseMemoryUsage() to get the amount of memory in the base class. If in a more distant descendant class, call Base::countMemory(counter, false) to count the memory in Base and above, excluding sizeof(Base).

void GA_ATIBlindData::replace ( const GA_Attribute & src )

overridevirtual

This replaces the entirety of this attribute's content and non- storage metadata (except the name) with that of the src attribute. The matchesStorage(src) should already return true. This is primarily for use by GA_AttributeSet::replace(). NOTE: The internal content sizes may not match exactly if the attribute type may overallocate, but the sizes should be such that any real data will fit in the destination, so be careful and deal with the myTailInitialize flag appropriately if any extra elements aren't equal to the default.

Implements GA_Attribute.
