Class LoadImplicitClosureInstr

java.lang.Object

org.jruby.ir.instructions.Instr

org.jruby.ir.instructions.ResultBaseInstr

org.jruby.ir.instructions.NoOperandResultBaseInstr

org.jruby.ir.instructions.LoadImplicitClosureInstr

All Implemented Interfaces:

FixedArityInstr, ResultInstr

public class LoadImplicitClosureInstr
extends NoOperandResultBaseInstr
implements FixedArityInstr

Load the "implicit" closure for this scope. Currently this is always the "block" passed to a body of code on the JVM stack.

Method Details

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.

decode

public static LoadImplicitClosureInstr decode(IRReaderDecoder d)

visit

public void visit(IRVisitor visitor)

Overrides:

visit in class Instr
