org.jikesrvm.compilers.opt.ir.operand
Class ObjectConstantOperand

java.lang.Object
  org.jikesrvm.compilers.opt.ir.operand.Operand
      org.jikesrvm.compilers.opt.ir.operand.ConstantOperand
          org.jikesrvm.compilers.opt.ir.operand.ObjectConstantOperand

Direct Known Subclasses:: ClassConstantOperand, StringConstantOperand

public class ObjectConstantOperand
extends ConstantOperand
extends ConstantOperand

Represents a constant object operand (for example, from an initialized static final).

See Also:: Operand

Field Summary
`private boolean`	`movable` Can this object be moved in memory?
`Offset`	`offset` Offset in JTOC where this object constant lives.
`Object`	`value` The non-`null` object value

Fields inherited from class org.jikesrvm.compilers.opt.ir.operand.Operand
`instruction`

Constructor Summary
`ObjectConstantOperand(Object v, Offset i)` Construct a new object constant operand

Method Summary
`Operand`	`copy()` Return a new operand that is semantically equivalent to `this`.
`TypeReference`	`getType()` Return the `TypeReference` of the value represented by the operand.
`boolean`	`isMovableObjectConstant()` Is the operand a movable `ObjectConstantOperand`?
`boolean`	`isRef()` Does the operand represent a value of the reference data type?
`boolean`	`similar(Operand op)` Are two operands semantically equivalent?
`String`	`toString()` Returns the string representation of this operand.
