org.jruby.ir.instructions.ruby19.ReceivePostReqdArgInstr

All Implemented Interfaces:

ResultInstr

public class ReceivePostReqdArgInstr
extends ReceiveArgBase

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 and Description
int	postReqdArgsCount The method/block parameter list has these many required parameters after opt+rest args
int	preReqdArgsCount The method/block parameter list has these many required parameters before opt+rest args

Method Summary

Modifier and Type	Method and Description
Instr	cloneForBlockCloning(InlinerInfo ii) Clone the instruction so it can be used in a cloned block which is present in a scope that itself or an ancestor scope (in the case of nested blocks) is being inlined.
Instr	cloneForInlinedScope(InlinerInfo ii) Clone the instruction (present in a method/closure) so it can be inlined into another scope.
IRubyObject	receivePostReqdArg(IRubyObject[] args, int kwArgHashCount)
java.lang.String	toString()
void	visit(IRVisitor visitor)

Field Detail

preReqdArgsCount

postReqdArgsCount

public final int postReqdArgsCount

The method/block parameter list has these many required parameters after opt+rest args

Constructor Detail

ReceivePostReqdArgInstr

public ReceivePostReqdArgInstr(Variable result,
                               int index,
                               int preReqdArgsCount,
                               int postReqdArgsCount)

Method Detail

toString

public java.lang.String toString()

Overrides:

toString in class ReceiveArgBase

cloneForInlinedScope

public Instr cloneForInlinedScope(InlinerInfo ii)

Description copied from class: Instr

Clone the instruction (present in a method/closure) so it can be inlined into another scope. This requires renaming variables and labels to eliminate naming conflicts.

Overrides:

cloneForInlinedScope in class Instr

Returns:

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

cloneForBlockCloning

public Instr cloneForBlockCloning(InlinerInfo ii)

Description copied from class: Instr

Clone the instruction so it can be used in a cloned block which is present in a scope that itself or an ancestor scope (in the case of nested blocks) is being inlined. This requires renaming variables to eliminate naming conflicts. Labels need not be renamed.

Overrides:

cloneForBlockCloning in class Instr

Returns:

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

receivePostReqdArg

public IRubyObject receivePostReqdArg(IRubyObject[] args,
                                      int kwArgHashCount)

visit

public void visit(IRVisitor visitor)

Overrides:

visit in class Instr
