Luna::query_interface

template <typename _Ity>
_Ity * query_interface(object_t object)

Gets one interface pointer from one pointer to one boxed object that implements the interface.

Parameters

• in object

  The pointer to the boxed object to query interface from.

Return value

Returns the specified interface pointer for the boxed object. Returns nullptr if the specified interface is not implemented by the specified boxed object.

Remark

The template version of query_interface provides a more convenient way to fetch one interface pointer from one boxed object pointer like so:

[object_t](group___runtime_object_1ga4d287a1c3bd0821c2391f4613686e35a.md) object = ...;
Interface1* i = query_interface<Interface1>(object);
