	The Type this handle is pointer at.

Public Member Functions

Public Attributes

	The ManagedPtr never access objects directly, so this is just an implementation detail.

Detailed Description

Sample implementation for a ManagedPtr.

This one is pretty useless, and serves as just an example. Any class that implements at least the member function this implements can be used with the ManagedPtr to get smart pointer semantics.

Member Function Documentation

void Mezzanine::IntHandle::Deconstruct ( )

inline

This can perform any cleanup, but should not fail if Pointer is NULL.

Copying or assigning a ManagedPtr just changes which instance of the ManagedPtr will cleanup Ptr. This movement of ownership allows passing or returning ManagedPtr by value or putting it in a standard container. Only the most recent copy will delete the target and none of the earlier copies will. This also stops the target from being deleted multiple times.

TargetPtrType Mezzanine::IntHandle::GetPointer ( )

inline

This is what the ManagedPtr with use for dereferencing.

Returns

The pointer to the managed data. This is expected to return a value that resolves to false when used as a condition when invalid.

Definition at line 86 of file managedptr.h.

void Mezzanine::IntHandle::SetPointer ( TargetPtrType  Value )

inline

This is what ManagedPtr will use in copy and assignment operations as well as invaliding handles.

Parameters

Value

The new value for the pointer. If NULL the only thing that the ManagedPtr will do to the handle is call its deconstruct method.
