Detailed Description

A simple ATI to store aribtrary "blobs" of data in an attribute.

The blob attribute type stores arbitrary blobs (GA_Blob) of data for each element in the attribute array. The blobs are stored as reference counted shared objects, meaning the blobs may be shared between multiple elements of the array. Each blob is referenced by a unique integer handle.

It's also possible to get a list of all the blobs stored by the attribute

By default, the array is filled with NULL pointers.

This class is very simple and only provides a minimal interface. Blob attributes are not saved/loaded, and there is minimal access to the blobs.

Users may sub-class from this ATI to create more complicated classes which provide alternate interfaces.

This attribute looks for options (GA_Attribute::getOptions())

bool blob:stringset (default: true)
This option is queried when merging detail attributes. When true, the unique blobs from both details will be merged into the resulting detail. When false, the resulting detail will only have the blobs from the first detail in the merge.

void GA_ATIBlob::countMemory	(	UT_MemoryCounter &	counter,

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).

bool GA_ATIBlob::matchesStorage ( const GA_Attribute * that ) const

inlineoverridevirtual

Returns true iff that is an attribute whose content can be copied from this without any type conversions. This is important to avoid reallocation of an attribute if its storage type, including tuple size, matches the source attribute exactly.

Reimplemented from GA_Attribute.

bool GA_ATIBlob::needDestruction ( ) const

Blob attributes need each element to properly destruct for accurate reference counting.

Reimplemented from GA_Attribute.

void GA_ATIBlob::reconstructElementBlock	(	GA_Offset	offset,
		GA_Offset	nelements
	)

overridevirtual

When the array size is grown, attributes should initialize the value appropriately. When elements are reused, however, reconstructElementBlock is called. This happens if an element is deleted and then a new element is allocated (using the existing slot)

Implements GA_Attribute.

void GA_ATIBlob::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. 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.

bool GA_ATIBlob::replaceBlob	(	GA_BlobIndex	handle,

Replace a blob in the blob container with a new blob value.

Grow or shrink the array size.

Implements GA_Attribute.

Store a new blob at the given offset.

bool GA_ATIBlob::setBlobIndex	(	GA_BlobIndex	blob_index,
		GA_Offset	offset,

Store a new blob_index at the given offset.

bool GA_ATIBlob::setBlobIndex	(	GA_BlobIndex	blob_i,
		const GA_Range &	di,
		int	tuple_index = `0`

Store a new blob_index at the given range of offsets.
