Notes:	This is an ABL specific abstraction that uses only dynamic
	constructs to access temp-tables and buffers in order to
	allow it to be reused by subclasses that have different
	temp-tables.
	- The most important behavioral encapsulation/reuse provided by
	this is the management of the size().
	Purpose: Abstract collection class
	Notes: All temp-table operations are dynamic
	Subclasses should define internal temp-table and pass the
	handle to super the constructor. They must override
	findBufferUseObject (see below) and could also override other
	methods with static code for performance.

Clear ()

Progress.Lang.Object Clone ()

/* Deep clone. or rather deep enough since we don't know what the elements' Clone() operations do, so this may end up being a memberwise clone */

CloneElements (ICollection)

LOGICAL Contains (Object)

LOGICAL ContainsAll (ICollection)

FindBufferUseObject (Object)

/* override this in subclass - used by remove(obj) and others */

LOGICAL IsEmpty ()

OpenEdge.Core.Collections.IIterator Iterator ()

/* Returns a new IIterator over the collection. */

LOGICAL Remove (Object)

LOGICAL RemoveAll (ICollection)

Resize ()

/** Recalculates the Size of this collections. Used particularly by Lists since there are operations like Remove() that are index-based and not item-based. */

LOGICAL RetainAll (ICollection)

Progress.Lang.Object ToArray ()

/* ToArray should not be used with large collections If there is too much data the ABL will throw: Attempt to update data exceeding 32000. (12371) */
