#include <weakrawptr.h>

Detailed Description

template<typename TYPE>
class maxon::WeakRawPtr< TYPE >

WeakRawPtr allows to create weak references to all memory blocks and objects created with NewObj() or NewMem().

Note: : in multithreaded use it might happen that the destructor of the object is already called but the memory block is still linked.
Int* rawPtr = NewObj(Int) iferr_return;

WeakRawPtr<Int> link;

link.Set(rawPtr);

Int* get01 = link.Get();

DebugAssert(get01 != nullptr);

DeleteObj(rawPtr);

Int* get02 = link.Get();

DebugAssert(get02 == nullptr);

WeakRawPtr ( )

default

Default constructor.

◆ WeakRawPtr() [2/4]

Explicit constructor to create the weak link with the connected target.

◆ WeakRawPtr() [3/4]

WeakRawPtr ( const WeakRawPtr< TYPE > & c )

Copy constructor.

◆ WeakRawPtr() [4/4]

WeakRawPtr ( WeakRawPtr< TYPE > && src )

◆ Get()

TYPE* Get ( ) const

Returns the target that is linked to the weak link.

Returns: Target pointer, otherwise nullptr if the object was freed in the meanwhile.

◆ GetProxy()

WeakRawPtrProxy GetProxy ( ) const

Returns the target that is linked to the weak link.

Returns: Proxy for the target pointer, otherwise nullptr if the object was freed in the meanwhile.

◆ Set()

void Set ( TYPE * target )

Sets a new target to the weak link.

Parameters

[in] target Object to be linked.
