RRef Class Reference

class RRef : public RRefBase

Contains, or packages, a copy of an instance of another class.

The template parameter defines the type of the contained object.

The contained object is held in allocated memory, and can be accessed through the member selection and dereference operators.

Constructor & Destructor Documentation

RRef()

RRef ( ) [inline]

Default constructor.

RRef(const RRef< T > &)

RRef ( const RRef < T > & anObject ) [inline]

Copy constructor.

The constructor frees any existing contained object, and takes ownership of the object owned by anObject.

Parameters

const RRef < T > & anObject A reference to another 'reference' object. On return from this constructor, anObject may be safely orphaned if it lives on the program stack.

Member Functions Documentation

Alloc(const T &)

void Alloc ( const T & anObject ) [inline]

Creates a copy of the specified object, which is to be contained by this reference object.

The amount of memory set aside to contain the object is defined by the size of the object

Parameters

const T & anObject The object to be packaged up by this reference object.

Alloc(const T &, TInt)

void Alloc ( const T & anObject,
TInt aSize
) [inline]

Creates a copy of the specified object, which is to be contained by this reference object.

The amount of memory set aside to contain the object is defined by aSize.

Parameters

const T & anObject The object to be packaged up by this reference object.
TInt aSize The amount of memory to be set aside to contain the object. You must make sure that this is big enough.

AllocL(const T &)

void AllocL ( const T & anObject ) [inline]

Creates a copy of the specified object, which is to be contained by this reference object, and leaves on failure.

The amount of memory set aside to contain the object is defined by the size of the object

Parameters

const T & anObject The object to be packaged up by this reference object.

AllocL(const T &, TInt)

void AllocL ( const T & anObject,
TInt aSize
) [inline]

Creates a copy of the specified object, which is to be contained by this reference object, and leaves on failure.

The amount of memory set aside to contain the object is defined by aSize.

Parameters

const T & anObject The object to be packaged up by this reference object.
TInt aSize The amount of memory to be set aside to contain the object. You must make sure that this is big enough.

operator T *()

operator T * ( ) [inline]

Gets a pointer to the contained object.

operator->()

T * operator-> ( ) [inline]

Gets a pointer to the contained object.

operator=(const RRef< T > &)

void operator= ( const RRef < T > & anObject ) [inline]

Assignment operator.

The constructor frees any existing contained object, and takes ownership of the object owned by anObject.

Parameters

const RRef < T > & anObject A reference to another 'reference' object. On return from this constructor, anObject may be safely orphaned if it lives on the program stack.
