protected boolean isReferenceType ( byte type ) { return type == Const . T_OBJECT || type == Const . T_ARRAY || type == T_NULL || type == T_EXCEPTION ; }
Determine if the given typecode refers to a reference type . This implementation just checks that the type code is T_OBJECT T_ARRAY T_NULL or T_EXCEPTION . Subclasses should override this if they have defined new object types with different type codes .
