Member Function Documentation

is()

template<typename T >

bool P4::RTTI::Base::is ( ) const

inlinenodiscardnoexcept

Checks if given object is of specified dynamic type. Same as isA, but typeid to check with is derived from template argument.

isA()

virtual bool P4::RTTI::Base::isA ( TypeId typeId ) const

nodiscardpure virtualnoexcept

Checks if given object is of specified dynamic type.

Parameters

typeid

to check with

to()

template<typename T >

T * P4::RTTI::Base::to ( )

inlinenodiscardnoexcept

Casts current object to a given type T. Overall the semantics is similar to that of dynamic_cast, however, relies on custom RTTI metadata and intrusive annotation.

Returns

nullptr if object is not compatible with T (e.g. if T is not among its base classes), casted pointer to object of T* type otherwise.

typeId()

virtual TypeId P4::RTTI::Base::typeId ( ) const

nodiscardpure virtualnoexcept

Queries information about dynamic type of an object.

Returns

typeid of current object.
