    • J9_CP_TYPE

      public static long J9_CP_TYPE(U32Pointer cpShapeDescription, int index) throws CorruptDataException
      This method is Java implementation of the define J9_CP_TYPE in j9cp.h in VM. It basically find out the type of the constant pool entry at the given index. #define J9_CP_TYPE(cpShapeDescription, index) \ (((cpShapeDescription)[(index) / J9_CP_DESCRIPTIONS_PER_U32] >> \ (((index) % J9_CP_DESCRIPTIONS_PER_U32) * J9_CP_BITS_PER_DESCRIPTION)) & J9_CP_DESCRIPTION_MASK)
      Parameters:
      cpShapeDescription - Description of the constantPool
      index - Type index
      Returns:
      Type
      Throws:
      CorruptDataException
