public FeedMaker getFeedMaker(int arg) throws XPathExceptionDescription copied from class:
StreamingAdjunctGet 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.
arg- identifies the argument with respect to which the expression is to be inverted: usually 0 to indicate the first argument is the value that is streamed. Argument numbering is the same as the sequence of arguments/operands returned by the method
- a FeedMaker to evaluate the expression, or null if it is not streamable with respect to the specificed argument.
XPathException- in the event of a failure
