Detailed Description

Objects stored in GABC_IArchives

Since IArchives keep references to objects, holding onto a reference will prevent the archive from closing. When we try to close an archive (i.e. so that we can write over it), we can't have any references dangling. The GABC_IArchive maintains a set of all the items and can force them to purge their data.

virtual void GABC_NAMESPACE::GABC_IItem::purge ( )
pure virtual

Purge any references to objects in the Alembic archive. Once the object is purged, it should be considered to be an invalid object. The object does not have to re-resolve itself.

The purge() method should not alter the base class archive.


void GABC_NAMESPACE::GABC_IItem::setArchive ( const GABC_IArchivePtr a)
