Detailed Description

Implements RTTI (run-time type information) for objects.

This is a simple, fast, and lightweight implementation of the RTTI feature. It provides the ability to check whether an object is of a given type and to cast it to the type specified as a template parameter.

It is extensively used to implement components (ksComponent) and to easily manage components within the application (ksApplication).

◆ as() [1/2]

template<typename TType >

TType * ksf::ksRtti::as ( )

inline

Tries to cast object to the type provided as a template parameter.

Template Parameters

TType Target type.
