Constructor & Destructor Documentation

~CObjectConIx()

IMPORT_C CObjectConIx::~CObjectConIx

(

)

Destructor.

Frees all resources owned by the container index, prior to its destruction.

In particular, it destroys all of its contained object containers.

CObjectConIx()

IMPORT_C CObjectConIx::CObjectConIx ( )

protected

Default constructor.

(generated from Symbian Developer Library)

Member Function Documentation

CreateContainerL()

IMPORT_C void CObjectConIx::CreateContainerL ( CObjectCon *&  anObject )

protected

Actually create the container.

(generated from Symbian Developer Library)

CreateL()

IMPORT_C CObjectCon * CObjectConIx::CreateL

(

)

Creates a new object container and adds it into this container index's collection.

In addition to creating the object container, the function assigns the next available unique ID to it.

(generated from Symbian Developer Library)

Lookup()

IMPORT_C CObjectCon * CObjectConIx::Lookup

(

TInt

aFindHandle

)

const

Gets a pointer to the object container with the unique ID from the specified find handle.

Parameters

aFindHandle

The find handle.

(generated from Symbian Developer Library)

NewL()

static IMPORT_C CObjectConIx * CObjectConIx::NewL ( )

static

Creates a new container index.

(generated from Symbian Developer Library)

Remove()

IMPORT_C void CObjectConIx::Remove

(

CObjectCon *

aCon

)

Removes the specified object container from this container index and deletes it.

Parameters

aCon	A pointer to the object container to be removed. If the pointer is NULL, the function just returns.

Panic condition: E32USER-CBASE 36 if the object container cannnot be found.
