Detailed Description

template<class T>
class RRef< T >

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.

API status: Published to all clients. Released API.

Definition at line 4801 of file e32std.h.

Constructor & Destructor Documentation

◆ RRef() [1/2]

template<class T >

RRef< T >::RRef ( )

inline

Default constructor.

(generated from Symbian Developer Library)

◆ RRef() [2/2]

template<class T >

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

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 Function Documentation

◆ Alloc() [1/2]

template<class T >

void RRef< T >::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

anObject The object to be packaged up by this reference object.

(generated from Symbian Developer Library)

◆ Alloc() [2/2]

template<class T >

void RRef< T >::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

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

◆ AllocL() [1/2]

template<class T >

void RRef< T >::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

anObject The object to be packaged up by this reference object.

(generated from Symbian Developer Library)

◆ AllocL() [2/2]

template<class T >

void RRef< T >::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

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

◆ operator T*()

template<class T >

RRef< T >::operator T* ( )

inline

Gets a pointer to the contained object.

(generated from Symbian Developer Library)

◆ operator->()

template<class T >

T * RRef< T >::operator-> ( )

inline

Gets a pointer to the contained object.

(generated from Symbian Developer Library)

◆ operator=()

template<class T >

void RRef< T >::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

anObject A reference to another 'reference' object. On return from this constructor, anObject may be safely orphaned if it lives on the program stack.
