org.jruby.ast.ArgsNode

All Implemented Interfaces:

ISourcePositionHolder, ParseResult

public class ArgsNode
extends Node

Represents the argument declarations of a method. The fields: foo(p1, ..., pn, o1 = v1, ..., on = v2, *r, q1, ..., qn, k1:, ..., kn:, **K, &b) p1...pn = pre arguments o1...on = optional arguments r = rest argument q1...qn = post arguments (only in 1.9) k1...kn = keyword arguments K = keyword rest argument b = block arg
