Detailed Description

Normally when RTTI is used compiler will generate type information for every possible type in program - this can introduce huge binary bloat. TypeId class in oposition allow you to compare types in runtime only with marginal overhead and only for types which are really needed. This technique is well known and used in many serious projects - for example in LLVM. Most important trick is create() method, rest is just syntactic sugar.

Constructor & Destructor Documentation

rili::TypeId::TypeId ( TypeId const &  other )

default

copy constructor

Parameters

other

TypeId object

rili::TypeId::TypeId ( )

inline

TypeId default constructor constructs invalid TypeId (no real type can have equal TypeId)

Member Function Documentation

template<typename T >

static TypeId rili::TypeId::create ( )

inlinestaticnoexcept

create rili::TypeId instance for given, known in compile time type.

Returns

TypeId object instance for given in template Parameter type.

bool rili::TypeId::operator!= ( TypeId const &  other ) const

inline

compare operator

Parameters

other

TypeId object

Returns

false if other was created for the same type, otherwise true

other

TypeId object

Returns

reference pointing to current TypeId instance

bool rili::TypeId::operator== ( TypeId const &  other ) const

inline

compare operator

Parameters

other

TypeId object

Returns

true if other was created for the same type, otherwise false
