Public Delegate Function CanProcessItemFunctionSignature ( 
	item As T
) As Boolean

)

type CanProcessItemFunctionSignature = 
    delegate of 
        item : 'T -> bool

function(item);

Parameters

item  T

Item to be checked for processing availability.

Return Value

Implementation of this function is optional. It is assumed that an item can be processed if this function is not defined

Items must eventually get to a state where they can be processed, or they will remain in the ProcessQueueT indefinitely.

Note that when this function is implemented and ProcessingStyle = ManyAtOnce (i.e., ProcessItemsFunction is defined), then each item presented for processing must evaluate as "CanProcessItem = True" before any items are processed.
