Constructor Detail

AttrAssignInstr

public AttrAssignInstr(Operand obj,
                       RubySymbol attr,
                       Operand[] args,
                       boolean isPotentiallyRefined)

Method Detail

create

public static AttrAssignInstr create(Operand obj,
                                     RubySymbol attr,
                                     Operand[] args,
                                     boolean isPotentiallyRefined)

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.

Overrides:

clone in class NoResultCallInstr

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.

encode

public void encode(IRWriterEncoder e)

Overrides:

encode in class CallBase

decode

public static AttrAssignInstr decode(IRReaderDecoder d)

interpret

public java.lang.Object interpret(ThreadContext context,
                                  StaticScope currScope,
                                  DynamicScope dynamicScope,
                                  IRubyObject self,
                                  java.lang.Object[] temp)

Overrides:

interpret in class CallBase

visit

public void visit(IRVisitor visitor)

Overrides:

visit in class NoResultCallInstr
