ChainInterfaces::IidCount Constant

The total number of interface IDs contained in the interfaces specified by template parameters I0 through I9.

static const unsigned long IidCount = Details::InterfaceTraits<I0>::IidCount + Details::InterfaceTraits<I1>::IidCount + Details::InterfaceTraits<I2>::IidCount + Details::InterfaceTraits<I3>::IidCount + Details::InterfaceTraits<I4>::IidCount + Details::InterfaceTraits<I5>::IidCount + Details::InterfaceTraits<I6>::IidCount + Details::InterfaceTraits<I7>::IidCount + Details::InterfaceTraits<I8>::IidCount + Details::InterfaceTraits<I9>::IidCount;

Return Value

The total number of interface IDs.

Remarks

Template parameters I0 and I1 are required, and parameters I2 through I9 are optional.The IID count of each interface is typically 1.
