- - ### Method Detail

    - #### getType

          public Type getType(ConstantPoolGen cp)

      Specified by:
        `getType` in interface `TypedInstruction`
      Returns:
        return address type

    - #### physicalSuccessor

          public InstructionHandle physicalSuccessor()

      Returns an InstructionHandle to the physical successor of this JsrInstruction. For this method to work, this JsrInstruction object must not be shared between multiple InstructionHandle objects! Formally, there must not be InstructionHandle objects i, j where i != j and i.getInstruction() == this == j.getInstruction().
      Returns:
        an InstructionHandle to the "next" instruction that will be executed when RETurned from a subroutine.
