The IDLitOperation::Init function method initializes the IDLitOperation object and sets properties that define the behavior the operation provides.
| Note An operation based on the IDLitOperation class must implement this method. See Creating an Operation for details. |
| Note Init methods are special life cycle methods, and as such cannot be called outside the context of object creation. This means that in most cases, you cannot call the Init method directly. There is one exception to this rule: if you write your own subclass of this class, you can call the Init method from within the Init method of the subclass. |
Obj = OBJ_NEW('IDLitOperation' [, PROPERTY=variable] )
or
Result = Obj->[IDLitOperation::]Init( [, PROPERTY=variable]) (In a lifecycle method only.)
When this method is called indirectly, as part of the call to the OBJ_NEW function, the return value is an object reference to the newly-created object.
When called directly within a subclass Init method, the return value is 1 if initialization was successful, or zero otherwise.
None
Any property listed under IDLitOperation Properties that contains the word "Yes" in the "Init" column of the properties table can be initialized during object creation using this method. To initialize the value of a property, specify the property name as a keyword set equal to the appropriate property value.
