CMsvServerEntry Class Reference

class CMsvServerEntry : public CActive

Accesses and acts upon a particular Message Server entry.

It provides similar functionality to that which CMsvEntry gives to client-side programs. The current entry that a CMsvServerEntry object relates is similarly referred to as its context.

A difference to note is that CMsvEntry functions, when used on a remote context, can result in requests to Server-side MTMs to change data on a remote server, as well as the local Message Server index. Naturally, as CMsvServerEntry is designed to be used by Server-side MTMs themselves, its comparable functions only alter the Message Server index.

A CBaseServerMTM-derived object gets an initial CMsvServerEntry on construction. It can get further CMsvServerEntry objects by calling NewEntryL(). The context can be changed by SetEntry().

The context is locked, preventing it being accessed by other MTMs. The lock is released when the object is deleted, or the context changes.

As with CMsvEntry, CBaseServerMTM functions can be divided into two broad groups. The first provides means to access the various types of storage associated with an entry. The second provides a means to discover and access other entries that the entry owns (its children).

)

Moves a selection of children of the context to another entry that belongs to a different service. All descendants will be moved as well.

If the function leaves, no changes are made.

In pre-Unicode versions an asynchronous move can be cancelled through CancelMoveEntry(); in other releases, use Cancel().

leave
KErrInUse The store or a file associated with the entry is open
leave
KErrNoMemory A memory allocation failed
leave

NewEntryL(TMsvId)

IMPORT_C CMsvServerEntry *NewEntryL(TMsvIdaId)

Gets a new CMsvServerEntry object for the specified entry ID.

The call locks the entry, preventing it being accessed by other clients.

The object must be deleted when it is no longer required. The lock is released when the object is deleted or the context is changed with SetEntry().

leave
KErrLocked Entry is locked
leave
KErrNoMemory A memory allocation failed
leave
KErrNotFound The entry does not exist

Parameters

TMsvId aIdID of the entry to access

NewL(CMsvServer &, TMsvId)

IMPORT_C CMsvServerEntry *NewL(CMsvServer &aServer,
TMsvIdaId
)[static]

Parameters

CMsvServer & aServer
TMsvId aId

OwningService()

IMPORT_C TMsvIdOwningService()const

Gets the ID of the service that owns the context.

Local entries are considered as being members of the local service.

If the entry is the root, then the root ID (KMsvRootIndexEntryId) is returned.

ReadStoreL()

IMPORT_C CMsvStore *ReadStoreL()

Obtains the message store for the current context with read-only access.

Multiple clients can read from a store simultaneously. If another client is already writing to the store, the function leaves with KErrAccessDenied.

The returned CMsvStore must be deleted when it is no longer required.

leave
KErrAccessDenied Store is locked by another process
leave
KErrNoMemory Not enough memory to open store
leave
KErrNotFound There is no store associated with this entry

RunL()

voidRunL()[protected, virtual]

Handles an active object's request completion event.

A derived class must provide an implementation to handle the completed request. If appropriate, it may issue another request.

The function is called by the active scheduler when a request completion event occurs, i.e. after the active scheduler's WaitForAnyRequest() function completes.

Before calling this active object's RunL() function, the active scheduler has:

1. decided that this is the highest priority active object with a completed request

2. marked this active object's request as complete (i.e. the request is no longer outstanding)

RunL() runs under a trap harness in the active scheduler. If it leaves, then the active scheduler calls RunError() to handle the leave.

Note that once the active scheduler's Start() function has been called, all user code is run under one of the program's active object's RunL() or RunError() functions.

CActiveScheduler::Start CActiveScheduler::Error CActiveScheduler::WaitForAnyRequest TRAPD

SetEntry(TMsvId)

IMPORT_C TIntSetEntry(TMsvIdaId)

Changes the context of the specified entry.

The call locks the entry, preventing it from being accessed by other clients. The lock is released when the object is deleted or the context is changed.

Note that you can change the context to KMsvNullIndexEntryId to unlock an entry without locking another.

Parameters

TMsvId aIdID of the entry to access

SetMtm(TUid)

voidSetMtm(TUidaMtm)[inline]

Sets this MTM sorting type to specified UID. When children of an entry are sorted, entries belonging to the same MTM type can be grouped together.

Parameters

TUid aMtmUID of MTM for sort

SetSort(TMsvSelectionOrdering &)

voidSetSort(TMsvSelectionOrdering &aOrdering)[inline]

Sets the sort order that is used when listing children, for example with GetChildren().

Parameters

TMsvSelectionOrdering & aOrderingSort order to use

Sort()

const TMsvSelectionOrdering &Sort()[inline]

Gets the current sort order of children of the entry.
