All Implemented Interfaces:

FixedArityInstr, ResultInstr

public class ReceivePostReqdArgInstr
extends ReceiveArgBase
implements FixedArityInstr

This represents a required arg that shows up after optional/rest args in a method/block parameter list. This instruction gets to pick an argument based on how many arguments have already been accounted for by parameters present earlier in the list.

Field Summary

Fields

Modifier and Type	Field	Description
final int	optArgsCount	The method/block parameter list has a maximum of this many optional arguments
final int	postReqdArgsCount	The method/block parameter list has these many required parameters after opt+rest args
final int	preReqdArgsCount	The method/block parameter list has these many required parameters before opt+rest args
final boolean	restArg	Does this method/block accept a rest argument

optArgsCount

public final int optArgsCount

The method/block parameter list has a maximum of this many optional arguments

restArg

public final boolean restArg

Does this method/block accept a rest argument

postReqdArgsCount

Method Details

toStringNonOperandArgs

public String[] toStringNonOperandArgs()

Overrides:

toStringNonOperandArgs in class ReceiveArgBase

clone

public Instr clone(CloneInfo info)

Description copied from class: Instr

Clone the instruction for use in an inlining context (either when a scope is inlined into another scope, or when a block has to be cloned because its associated call belongs to an inlined scope). This might renaming variables and labels to eliminate naming conflicts. The implementation might vary on the cloning mode.

Specified by:

clone in class Instr

Parameters:

info - This object manages renaming of variables and labels, handles args and return values.

Returns:

a new instruction that can be used in the target scope.

encode

public void encode(IRWriterEncoder e)

Overrides:

encode in class ResultBaseInstr

decode

public static ReceivePostReqdArgInstr decode(IRReaderDecoder d)

receivePostReqdArg

public IRubyObject receivePostReqdArg(ThreadContext context,
 IRubyObject[] args,
 boolean acceptsKeywordArgument)

visit

public void visit(IRVisitor visitor)

Overrides:

visit in class Instr
