Examples of UserFunction

client.net.sf.saxon.ce.expr.instruct.UserFunction
This object represents the compiled form of a user-written function (the source can be either an XSLT stylesheet function or an XQuery function).
It is assumed that type-checking, of both the arguments and the results, has been handled at compile time. That is, the expression supplied as the body of the function must be wrapped in code to check or convert the result to the required type, and calls on the function must be wrapped at compile time to check or convert the supplied arguments.
