Smart Pointers

Module Description

The Smart Pointer package includes a generic singleton template class, a simple pointer wrapper, and two varieties of thread-safe reference-counted pointers. The Smart Pointer package also provides the Threads Module with the base classes for handle-body implementation.

See the Threads Module User's Guide for complete information on how to use the Smart Pointer package.

Classes
class	RWAtomicCounter
	Maintains a reference count safely in a multithreaded environment. More...
class	RWBodyBase
	Base class for body classes. More...
class	RWHandleBase
	Base class for all handle classes. Increments a reference count for each class instance that is bound to an instance of the RWBodyBase class. More...
class	RWTCountedPointer< Body >
	A smart pointer handle to a reference-counting body. More...
class	RWTCounter< Mutex >
	Deprecated. Maintains a reference count. More...
class	RWTCountingBody< Mutex >
	Base class for classes that must maintain a reference count. More...
class	RWTCountingPointer< Body, Counter >
	Defines a reference-counted pointer that provides reference counting semantics for types that do not directly support reference counting. More...
class	RWTOnlyPointer< Body >
	Simplifies the use of pointers that refer to objects on the heap, automatically destroying the object when the pointer object is itself destroyed. More...
class	RWTPointer< Body >
	Base class for smart-pointer classes. More...
class	RWTSingleton< T >
	Ensures that a class has only one instance and provides a global point of access to it. More...

Typedef Documentation

typedef RWTCounter<RWMutexLock> RWSafeCounter

Deprecated:

As of SourcePro 11.1, use RWAtomicCounter instead.

Header File

#include <rw/pointer/RWSafeCounter.h>

The typedef RWSafeCounter implements the multithread-safe reference counter, which can be used as the Counter template parameter for RWTCountingPointer.

Example

RWTCountingPointer<int, RWSafeCounter> pointer = new int(10);

typedef RWTCounter<RWNullMutexLock> RWUnsafeCounter

Deprecated:

As of SourcePro 11.1, use RWAtomicCounter.

Header File

#include <rw/pointer/RWUnsafeCounter.h>

A typedef that implements an unsafe counter that can be used for greater efficiency in reference counting in situations where multithread safety is not required. This typedef can be used as the Counter template parameter for RWTCountingPointer.

Example

RWTCountingPointer<int, RWUnsafeCounter> pointer = new int(10);
