Detailed Description

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

This is a simple, but fast and lightweight implementation of RTTI feature. Provides the ability to check whether object is of given type and cast it to the type provided as a template parameter.

Extensively used to implement components - ksComponent and easily manage components in the application (ksApplication).

Member Function Documentation

◆ 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.

Returns: Pointer to object of given type or nullptr if object is not of given type.

◆ as() [2/2]

template<typename TType >

const TType * ksf::ksRtti::as ( ) const

inline

Tries to cast object to the type provided as a template parameter (const version).

Template Parameters

TType Target type.

Returns: Const pointer to object of given type or nullptr if object is not of given type.

◆ getInstanceType()

virtual const size_t ksf::ksRtti::getInstanceType ( ) const

pure virtual

Retrieves type ID of the object.

Returns: Object type ID.

Implemented in ksf::comps::ksConfigProvider, ksf::comps::ksDevicePortal, ksf::comps::ksDevStatMqttReporter, ksf::comps::ksLed, ksf::comps::ksMqttConfigProvider, ksf::comps::ksMqttConnector, ksf::comps::ksResetButton, ksf::comps::ksWifiConfigurator, ksf::comps::ksWifiConnector, and ksf::ksComponent.

◆ isA()

virtual bool ksf::ksRtti::isA ( const size_t id ) const

inlinevirtual

Checks whether object is of given type.

Parameters

id	Type ID to check against.

Returns: True if object is of given type, otherwise false.
