CheckArgsArrayArityInstr

public CheckArgsArrayArityInstr(Operand argsArray,
                        int required,
                        int opt,
                        boolean rest)

Method Detail

getArgsArray

public Operand getArgsArray()

toStringNonOperandArgs

public String[] toStringNonOperandArgs()

Overrides:

toStringNonOperandArgs in class Instr

clone

public Instr clone(CloneInfo 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 might renaming variables and labels to eliminate naming conflicts. The implementation might vary on the cloning mode.

Specified by:

clone 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.

decode

public static CheckArgsArrayArityInstr decode(IRReaderDecoder d)

encode

public void encode(IRWriterEncoder e)

Overrides:

encode in class Instr

interpret

public Object interpret(ThreadContext context,
               StaticScope currScope,
               DynamicScope currDynScope,
               IRubyObject self,
               Object[] temp)

Overrides:

interpret in class Instr

visit

public void visit(IRVisitor visitor)

Overrides:

visit in class Instr
