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.
