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 and QMailMessages on the message store.

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

See also QMailMessage, QMailFolder, QMailMessageKey, QMailFolderKey, and QMailAccountKey.
