	TValue value
)

Public Delegate Function CanProcessItemFunctionSignature ( 
	key As TKey,
	value As TValue
) As Boolean

public delegate bool CanProcessItemFunctionSignature(
	TKey key, 
	TValue value
)

type CanProcessItemFunctionSignature = 
    delegate of 
        key : 'TKey * 
        value : 'TValue -> bool

function(key, value);

Parameters

key  TKey

key to be checked for processing availability.

value  TValue

value to be checked for processing availability.

Return Value

Implementation of this function is optional. It will be 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 ProcessDictionaryTKey, TValue indefinitely.

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