Abstract
Lazy evaluation is used for resolving references to recreatable external objects. A recreatable external object is an object whose state can easily be deallocated and later reconstituted or “activated” based on a much smaller sized descriptor. In one embodiment, a run-time external reference is used that specifies an index into a value array that holds the actual reference and a descriptor array. If the value array entry at the index is null, then the corresponding entry in the descriptor array is used to activate the external object and a reference to the activated external object is cached in the value array.
