System.Rtti | TVirtualInterface |
Description
Creates and initializes a TVirtualInterface instance.
TVirtualInterface creates an implementation of a specific interface at run time (the interface is specified by the PIID parameter.)
The parameters of Create are listed in the following table:
| Parameter | Description |
|---|---|
PIID
|
Type information for the target interface. You can get it with the help of TypeInfo. |
InvokeEvent
|
The event that is raised when a specific interface method is called. You can specify it in the constructor (optionally), or using the OnInvoke property. |
You should create a TVirtualInterface instance and immediately get the corresponding interface instance. You should never create a TVirtualInterface as a local variable. A TVirtualInterface instance has an associated reference counter and automatically frees itself.
