System.Variants | TInvokeableVariantType |
Description
Implements all the methods that do not return values.
Override DoProcedure to provide the implementation for methods calls that do not return values. When the application invokes a Variant member procedure (Delphi) or calls the Variant's Exec method (C++), a call that allows the TInvokeableVariant descendant to implement the call is automatically generated to DoProcedure.
The following table lists the parameters expected by this method.
| Value | Meaning |
|---|---|
|
V |
The TVarData record from the Variant instance that was used to call the procedure. |
|
Name |
The name of the procedure. |
|
Arguments |
Dynamic array of TVarData records, where each one represents the value of an argument passed to the procedure. |
DoProcedure returns True if it executes the procedure call, and False if it does not implement the specified procedure.
As implemented in TInvokeableVariant, DoProcedure always returns False, because it does not implement any procedure calls.
