Constructor Detail

GetFieldInstr

public GetFieldInstr(Variable dest,
                     Operand obj,
                     RubySymbol fieldName)

Method Detail

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 GetFieldInstr decode(IRReaderDecoder d)

getAccessor

public VariableAccessor getAccessor(IRubyObject o)

interpret

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