Parameters

TMemberFunction
Typename parameter for an ArgTraits structure that cannot match any Invoke method signature.
TDelegateInterface
A delegate interface.
TArg1
The type of the first argument of the Invoke method.
TArg2
The type of the second argument of the Invoke method.
TArg3
The type of the third argument of the Invoke method.
TArg4
The type of the fourth argument of the Invoke method.
TArg5
The type of the fifth argument of the Invoke method.
TArg6
The type of the sixth argument of the Invoke method.
TArg7
The type of the seventh argument of the Invoke method.
TArg8
The type of the eigth argument of the Invoke method.
TArg9
The type of the ninth argument of the Invoke method.

Remarks

The ArgTraits structure declares a specified delegate interface and an anonymous member function that has a specified number of parameters.
