FolderStorage Class Reference

#include <folderstorage.h>

Inheritance diagram for FolderStorage:

KMFolderIndex

List of all members.


Detailed Description

The FolderStorage class is the bass class for the storage related aspects of a collection of mail (a folder).

Accounts

The accounts (of KMail) that are fed into the folder are represented as the children of the folder. They are only stored here during runtime to have a reference for which accounts point to a specific folder.

Constructor & Destructor Documentation

FolderStorage::FolderStorage ( KMFolder folder,
const char *  name = 0 
)

Usually a parent is given.

But in some cases there is no fitting parent object available. Then the name of the folder is used as the absolute path to the folder file.

Definition at line 63 of file folderstorage.cpp.


Member Function Documentation

Definition at line 127 of file folderstorage.h.

void FolderStorage::updateChildrenState (  )  [virtual]

Updates the hasChildren() state.

Definition at line 1096 of file folderstorage.cpp.

KMMessage * FolderStorage::getMsg ( int  idx  )  [virtual]

Read message at given index.

Indexing starts at zero

Definition at line 477 of file folderstorage.cpp.

KMMsgInfo * FolderStorage::unGetMsg ( int  idx  )  [virtual]

Replace KMMessage with KMMsgInfo and delete KMMessage.

Definition at line 566 of file folderstorage.cpp.

bool FolderStorage::isMessage ( int  idx  )  [virtual]

Checks if the message is already "gotten" with getMsg.

Definition at line 591 of file folderstorage.cpp.

KMMessage * FolderStorage::readTemporaryMsg ( int  idx  )  [virtual]

Load message from file and do NOT store it, only return it.

This is equivalent to, but faster than, getMsg+unGetMsg WARNING: the caller has to delete the returned value!

Definition at line 527 of file folderstorage.cpp.

virtual DwString FolderStorage::getDwString ( int  idx  )  [pure virtual]

Read a message and returns a DwString.

FolderJob::JobType  jt = FolderJob::tGetMessage,
KMFolder folder = 0,
QString  partSpecifier = QString::null,
const AttachmentStrategy *  as = 0 
) const [virtual]

These methods create respective FolderJob (You should derive FolderJob for each derived KMFolder).

virtual const KMMsgBase* FolderStorage::getMsgBase ( int  idx  )  const [pure virtual]

Provides access to the basic message fields that are also stored in the index.

Whenever you only need subject, from, date, status you should use this method instead of getMsg() because getMsg() will load the message if necessary and this method does not.

Implemented in KMFolderIndex.

virtual const KMMsgBase* FolderStorage::operator[] ( int  idx  )  const [inline, virtual]

Same as getMsgBase(int).

Definition at line 175 of file folderstorage.h.

virtual KMMsgBase* FolderStorage::operator[] ( int  idx  )  [inline, virtual]

Same as getMsgBase(int).

This time non-const.

Definition at line 178 of file folderstorage.h.

KMMessage * FolderStorage::take ( int  idx  )  [virtual]

Usable to call addMsg() afterwards. Loads the message if it is not loaded up to now.

Definition at line 423 of file folderstorage.cpp.

virtual int FolderStorage::addMsg ( KMMessage msg,
int *  index_return = 0 
) [pure virtual]

Add the given message to the folder.

Usually the message is added at the end of the folder. Returns zero on success and an errno error code on failure. The index of the new message is stored in index_return if given. Please note that the message is added as is to the folder and the folder takes ownership of the message (deleting it in the destructor).

virtual int FolderStorage::addMsgKeepUID ( KMMessage msg,
int *  index_return = 0 
) [inline, virtual]

(Note(bo): This needs to be fixed better at a later point.

) This is overridden by dIMAP because addMsg strips the X-UID header from the mail.

Definition at line 196 of file folderstorage.h.

int FolderStorage::addMsg ( QPtrList< KMMessage > &  msgList,
QValueList< int > &  index_return 
) [virtual]

int FolderStorage::moveMsg ( KMMessage msg,
int *  index_return = 0 
) [virtual]

Definition at line 621 of file folderstorage.cpp.

virtual int FolderStorage::find ( const KMMsgBase *  msg  )  const [pure virtual]

Returns the index of the given message or -1 if not found.

Implemented in KMFolderIndex.

Definition at line 102 of file folderstorage.cpp.

virtual void FolderStorage::tryReleasingFolder ( KMFolder  )  [inline, virtual]

See also:
KMFolder::removeContents

Definition at line 755 of file folderstorage.cpp.

int FolderStorage::expunge (  )  [virtual]

Definition at line 157 of file folderstorage.cpp.

bool FolderStorage::needsCompacting (  )  const [inline]

Returns TRUE if the folder contains deleted messages.

Definition at line 328 of file folderstorage.h.

void FolderStorage::quiet ( bool  beQuiet  )  [virtual]

If set to quiet the folder will not emit msgAdded(idx) signal.

This is necessary because adding the messages to the listview one by one as they come in ( as happens on msgAdded(idx) ) is very slow for large ( >10000 ) folders. For pop, where whole bodies are downloaded this is not an issue, but for imap, where we only download headers it becomes a bottleneck. We therefore set the folder quiet() and rebuild the listview completely once the complete folder has been checked.
