Detailed Description

The QMailStore class represents the main interface for storage and retrieval of messages and folders on the message store.

The QMailStore class is accessed through a singleton interface and provides functions for adding, updating and deleting of QMailAccounts, QMailFolders, QMailThreads and QMailMessages on the message store.

QMailStore also provides functions for querying and counting of QMailFolders, QMailAccounts, QMailThreads and QMailMessages when used in conjunction with QMailFolderKey and QMailAccountKey, QMailThreadKey and QMailMessageKey classes.

If a QMailStore operation fails, the lastError() function will return an error code value indicating the failure mode encountered. A successful operation will set the lastError() result to QMailStore::NoError.

Messaging accounts are represented by QMailAccountId objects. The data associated with accounts is separated into two components: QMailAccount objects hold account properties exported to mail store client applications, and QMailAccountConfiguration objects hold data used only by the messageserver and the protocol plugins it loads.

Account objects are accessed via the account(), accountConfiguration(), countAccounts() and queryAccounts() functions. Accounts in the mail store can be manipulated via the addAccount(), updateAccount() and removeAccount() functions. Mail store manipulations affecting accounts are reported via the accountsAdded(), accountsUpdated(), accountContentsModified() and accountsRemoved() signals.

Thread (a.k.a. conversation) objects are accessed via the thread(), countThreads() and queryThreads() functions. Accounts in the mail store can be manipulated via the addThread(), updateThread() and removeThread() functions. Mail store manipulations affecting accounts are reported via the threadsAdded(), threadsUpdated(), threadsContentsModified() and threadsRemoved() signals.

Fixed logical groupings of message are modelled as folders, represented by QMailFolderId objects. The data associated with folders is held by instances of the QMailFolder class.

Folder objects are accessed via the folder(), countFolders() and queryFolders() functions. Folders in the mail store can be manipulated via the addFolder(), updateFolder() and removeFolder() functions. Mail store manipulations affecting folders are reported via the foldersAdded(), foldersUpdated(), folderContentsModified() and foldersRemoved() signals.

Messages in the mail store are represented by QMailMessageId objects. The data associated with a message can be retrieved in two forms: QMailMessageMetaData objects contain only the meta data fields associated with a message, and QMailMessage objects contain both the meta data fields and the message content proper.

Message objects are accessed via the message(), messageMetaData(), countMessages() and queryMessages() functions. Additionally, the messagesMetaData() function can be used to retrieve subsets of meta data pertaining to a set of messages. Messages in the mail store can be manipulated via the addMessage(), updateMessage() and removeMessage() functions. Multiple messages can have their meta data fields updated together via the updateMessagesMetaData() function. Mail store manipulations affecting messages are reported via the messagesAdded(), messagesUpdated(), messageContentsModified() and messagesRemoved() signals.

Messages that have been removed can be represented by removal records, which persist only to assist in keeping mail store content synchronized with the content of an external message source. QMailMessageRemovalRecord objects can be accessed via the messageRemovalRecords() function.
