Description
Instantiates a custom scope associated with either the type of the passed object or with the passed class reference.
The CreateScope method instantiates a custom scope associated with either the type of the passed object or with the passed class reference. There are four overloaded CreateScope methods, with their parameters described below.
Call the first overloaded CreateScope method with the parameters described below. This overloaded CreateScope method returns the custom scope instance.
| Parameter | Meaning |
AObject
|
The object that the custom scope will be able to use to create custom wrappers. |
MetaClass
|
The class reference to be used in the case the object is nil. MetaClass cannot be nil if the passed object is nil.
|
Call the second overloaded CreateScope method with the parameters described below. This overloaded CreateScope method returns True if it succeeds, False otherwise.
| Parameter | Meaning |
AObject
|
The object that the custom scope will be able to use to create custom wrappers. |
MetaClass
|
The class reference to be used in the case the object is nil. MetaClass cannot be nil if the passed object is nil.
|
CustomScope
|
If the function succeeds, it contains a reference to the custom scope instance. If no association is found for the passed class reference, then this parameter contains nil. |
Call the third overloaded CreateScope method with the parameters described below. It instantiates a custom scope associated with the type of the passed object. This overloaded CreateScope method returns the custom scope instance.
| Parameter | Meaning |
