◆ findHandlerForCommandAlwaysAllowed()

std::unique_ptr< Handler > Handler::findHandlerForCommandAlwaysAllowed ( Protocol::Command::Type cmd,
AkonadiServer & akonadi )
static

Find a handler for a command that is always allowed, like LOGOUT.

Parameters
cmdthe command string
Returns
an instance to the handler. The handler is deleted after
See also
handelLine is executed. The caller needs to delete the handler in case an exception is thrown from handelLine.

◆ findHandlerForCommandAuthenticated()

std::unique_ptr< Handler > Handler::findHandlerForCommandAuthenticated ( Protocol::Command::Type cmd,

static

Find a handler for a command that is allowed when the client is authenticated, like LIST, FETCH, etc.

Parameters
cmdthe command string
Returns
an instance to the handler. The handler is deleted after
See also
handelLine is executed. The caller needs to delete the handler in case an exception is thrown from handelLine.

◆ findHandlerForCommandNonAuthenticated()

std::unique_ptr< Handler > Handler::findHandlerForCommandNonAuthenticated ( Protocol::Command::Type cmd,
AkonadiServer & akonadi )
static

Find a handler for a command that is allowed when the client is not yet authenticated, like LOGIN.

Parameters
cmdthe command string
Returns
an instance to the handler. The handler is deleted after
See also
handelLine is executed. The caller needs to delete the handler in case an exception is thrown from handelLine.

Definition at line 40 of file handler.cpp.

◆ parseStream()

virtual bool Akonadi::Server::Handler::parseStream ( )
pure virtual

Parse and handle the IMAP message using the streaming parser.

The implementation MUST leave the trailing newline character(s) in the stream!

Returns
true if parsed successfully, false in case of parse failure
