public class ValuesMap extends MethodProc implements Inlineable
Map a function over a value sequence, yielding a new sequence. Normally, the function takes one argument, the item in the sequence. If startCounter is non-negative, a position index is also passed. Used to implement XQuery's 'for' form.

numArgs
public int numArgs()
Description copied from class:Procedure
ReturnminArgs()|(maxArgs<<12)
. We use a single virtual function to reduce the number of methods in the system, as well as the number of virtual method table entries. We shift by 12 so the number can normally be represented using a sipush instruction, without requiring a constant pool entry.
