Detailed Description

Base class for body classes. Each time an RWHandleBase instance is bound to an instance of this class, the handle instance increments the reference count inherited by the body instance. Each time a handle instance detaches from an instance of this class, the handle decrements the reference count. If the reference count reaches zero, the handle deletes the body instance. The reference counting relieves clients of the burden of having to keep track of when it is safe to delete a body instance.

Example

See HandlebodyEx1.cpp and HandlebodyEx2.cpp, located in the examples directory.

Constructor & Destructor Documentation

RWBodyBase() [1/3]

RWBodyBase::RWBodyBase ( void )

inlineprotected

Default constructor. Constructs a default body instance where the reference count starts at zero.

RWBodyBase() [2/3]

RWBodyBase::RWBodyBase ( RWStaticCtor )

inlineprotected

Constructs a static body instance where the reference count starts at one, to prevent deletion by handles.

RWBodyBase() [3/3]

RWBodyBase::RWBodyBase ( const RWBodyBase & second )

inlineprotected

Copy constructor.

~RWBodyBase()

virtual RWBodyBase::~RWBodyBase ( void )

protectedvirtual

Destructor. Throws no exceptions.

Member Function Documentation

operator=()

RWBodyBase & RWBodyBase::operator= ( const RWBodyBase & second )

inlineprotected

Assignment operator. Throws no exceptions.
