IDL_Object::_overloadOR

The IDL_Object::_overloadOR function method defines the behavior of the bitwise OR operator for instances of objects that inherit from the IDL_Object class.

This method is designed to replicate the default behavior of objects that do not use operator overloading. As a result, object classes that do inherit from the IDL_Object class but that do not override this particular method will behave in the same manner as object classes that do not inherit from the IDL_Object class.

Tip: If you write an object class that inherits from IDL_Object and overloads this method, you can call the superclass method directly to achieve the default behavior for specific cases.

Syntax

In most cases, this method is called indirectly by specifying an object reference as an argument on either the left or right side of the OR operator. When called explicitly, the syntax is:

Result = Obj->[IDL_Object::]_overloadOR( Left, Right )

Return Value

This method is called when an operand to the OR operator is an instance of a class that inherits from the IDL_Object class, but that does not implement its own _overloadOR method. The return value replicates the behavior of the OR operator with an object that does not inherit from the IDL_Object class.

Arguments

Left

The argument that appears on the left side of the operator. If the argument on the left side is the first instance of the overloaded object class, Left will be the same as the implicit self argument.

Right

The argument that appears on the right side of the operator. If the argument on the right side is the first instance of the overloaded object class, Right will be the same as the implicit self argument.

Keywords

None

Routine Signature

To overload the OR operator for an object class, implement a method with the following signature:

FUNCTION class::_overloadOR, Left, Right

The return value of this function should be the result of the overloaded OR operation.
