Detailed Description

Generic buffer container.

Function Documentation

◆ make_identity()

pfs_identity make_identity	(	pfs_container_id	container_id,
		pfs_page_id	page_id,
		pfs_object_id	object_id,
		pfs_dirty_state *	dirty_state
	)

Build an artificial object identity, for OBJECT_INSTANCE_BEGIN columns.

To be globally unique, identity consists of:

the container id, so objects A and B from different containers (instrument classes) will not collide. Note that partitioned containers get a container id per partition.
the page id within the container
the object index within the page
the version number from the pfs_lock dirty_state, to resolve ABA problems
