Constructor Detail

OptArgMultipleAsgnInstr

public OptArgMultipleAsgnInstr(Variable result,
                               Operand array,
                               int index,
                               int minArgsLength)

Method Detail

toString

public java.lang.String toString()

Overrides:

toString in class Instr

cloneForInlining

public Instr cloneForInlining(InlinerInfo ii)

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 requires renaming variables and labels to eliminate naming conflicts.

Overrides:

cloneForInlining in class Instr

Parameters:

ii - 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.

interpret

public java.lang.Object interpret(ThreadContext context,
                                  DynamicScope currDynScope,
                                  IRubyObject self,
                                  java.lang.Object[] temp,
                                  Block block)

Overrides:

interpret in class Instr

visit

public void visit(IRVisitor visitor)

Overrides:

visit in class Instr
