Method Detail

getFeedMaker

public FeedMaker getFeedMaker(int streamedArg)

Description copied from class: StreamingAdjunct

Get a FeedMaker, a factory class that creates a Feed to evaluate this expression in streaming mode. In many cases the StreamingAdjunct is itself a FeedMaker, in which case it returns itself. But where an expression has several operands, it will typically create different feeds depending on which argument is the streamed input, and in such cases the individual StreamingAdjunct makes the decision which feed to use, by returning an appropriate FeedMaker.

Overrides:

getFeedMaker in class StreamingAdjunct

Parameters:

streamedArg - 0 if the LHS operand is streamed, 1 if the RHS operand is streamed

Returns:

a feed factory
