public class ArgsNode

extends AbstractNode

arguments for a function. this is used both in the function definition and in actual function calls

• u1 ==> optNode (BlockNode) Optional argument description
• u2 ==> rest (int) index of the rest argument (the array arg with a * in front
• u3 ==> count (int) number of arguments

Constructor Detail

ArgsNode

public ArgsNode(ISourcePosition iPosition,
                int argsCount,
                IListNode optArgs,
                int restArg,
                BlockArgNode blockArgNode)

Parameters:

optArgs - Node describing the optional arguments This Block will contain assignments to locals (LAsgnNode)

restArg - index of the rest argument in the local table (the array argument prefixed by a * which collects all additional params) or -1 if there is none.

argsCount - number of regular arguments

blockArgNode - An optional block argument (&arg).
