Detailed Description

The destructor class provides a destructor for registered types.

A instance of a destructor class can only be obtained from the type class. See type::get_destructor().

Copying and Assignment

A destructor object is lightweight and can be copied by value. However, each copy will refer to the same underlying destructor.

Typical Usage

constructor string_ctor == type::get("std::string").get_constructor({type::get("const char*")});

variant my_string = string_ctor.invoke({"Hello World"}); // returns an ptr to the object on the heap

type::get("std::string").get_destructor().invoke(my_string);

my_string.is_valid(); // yield to false

Member Function Documentation

type rttr::destructor::get_destructed_type

(

)

const

Returns the rttr::type for which this destructor can delete objects.

Returns

The type of this destructor.

void rttr::destructor::invoke

(

variant &

obj

)

const

Destroys the given object obj.

Remarks

When the obj could be destroyed the given obj is invalid after calling this method; Otherwise it is still valid.

bool rttr::destructor::is_valid

(

)

const

Returns true whether this destructor object is valid; otherwise false.

Returns

Returns true when the destructor is valid; otherwise false.

rttr::destructor::operator bool

(

)

const

Convenience function to check if this destructor is valid or not.

Returns

True if this destructor is valid, otherwise false.

bool rttr::destructor::operator!=

(

const destructor &

other

)

const

Returns true if this destructor is the not the same like the other.

Returns

True if both destructors are different, otherwise false.

bool rttr::destructor::operator==

(

const destructor &

other

)

const

Returns true if this destructor is the same like the other.

Returns

True if both destructors are equal, otherwise false.
