AutoFree< TYPE > Class Template Reference

#include <ge_autoptr.h>

Detailed Description

template<class TYPE>
class AutoFree< TYPE >

This class handles automatic deallocation of objects with TYPE::Free(). It is similar in function to AutoAlloc, but the object has to have been previously allocated.

Constructor & Destructor Documentation

◆ AutoFree() [1/4]

AutoFree ( const AutoFree< TYPE > &  p)
private

◆ AutoFree() [2/4]

AutoFree ( )

Default constructor.

◆ AutoFree() [3/4]

AutoFree ( AutoFree< TYPE > &&  src)

◆ AutoFree() [4/4]

AutoFree ( TYPE *  p)
explicit

Stores the pointer p internally.

Parameters
[in]pA pointer to an object to be freed with TYPE::Free(p). The AutoFree instance takes over the ownership of the pointed object.

◆ ~AutoFree()

~AutoFree ( )

Calls TYPE::Free(ptr), where ptr is the internally stored pointer.

Member Function Documentation

◆ operator=()

const AutoFree<TYPE>& operator= ( const AutoFree< TYPE > &  p)
private

◆ MAXON_OPERATOR_MOVE_ASSIGNMENT()

MAXON_OPERATOR_MOVE_ASSIGNMENT ( AutoFree< TYPE >  )

◆ Set()

void Set ( TYPE *  p)

Sets p as the internal pointer.

Parameters
[in]pA pointer to an object to be freed with TYPE::Free(p). The AutoFree instance takes over the ownership of the pointed object.

◆ operator TYPE *()

operator TYPE * ( ) const

Conversion to a raw pointer to TYPE. Makes it possible to pass the object directly to functions like Function(TYPE* t).

Returns
The internal pointer. The AutoFree instance owns the pointed object.

◆ operator TYPE &()

operator TYPE & ( ) const

Conversion to a reference to TYPE. Makes it possible to pass the object directly to functions like Function(TYPE& t).

Note
This dereferences the internal pointer. Hence, it must not be nullptr.
Returns
A reference to the pointed object.

◆ operator->()

TYPE* operator-> ( ) const

Used for calls like myauto->Function().

Note
This dereferences the internal pointer. Hence, it must not be nullptr.
Returns
The internal pointer. The AutoFree instance owns the pointed object.

◆ operator&()

TYPE* const* operator& ( ) const

Used for expressions like &myauto. Extracts a pointer to the internal pointer.

Note
This means that it is impossible to get the address of the actual AutoFree instance.
Returns
A pointer to the internal pointer. The AutoFree instance owns the pointed object.

◆ Release()

TYPE* Release ( )

Retrieves the internal pointer and then sets it to nullptr. Thus the ownership is transfered to the caller.

Returns
The internal pointer. The caller takes over the ownership of the pointed object.

◆ Free()

void Free ( )

Calls TYPE::Free(ptr) with the internal pointer and sets it to nullptr.

◆ Assign()

void Assign ( TYPE *  p)

Assigns p as the internal pointer.

Parameters
[in]pA pointer to an object to be freed with TYPE::Free(p). The AutoFree instance takes over the ownership of the pointed object.
