=============
|
||||
|
||||
Since plugins are running within internal libtorrent threads, one convenient
|
||||
way to communicate with the client is to post custom alerts.
|
||||
|
||||
The expected interface of any alert, apart from deriving from the ``alert``
|
||||
base class, looks like this:
|
||||
|
||||
.. parsed-literal::
|
||||
|
||||
const static int alert_type = *<unique alert ID>*;
|
||||
virtual int type() const { return alert_type; }
|
||||
|
||||
virtual std::string message() const;
|
||||
|
||||
virtual std::auto_ptr<alert> clone() const
|
||||
{ return std::auto_ptr<alert>(new name(\*this)); }
|
||||
|
||||
const static int static_category = *<bitmask of alert::category_t flags>*;
|
||||
virtual int category() const { return static_category; }
|
||||
|
||||
virtual char const* what() const { return *<string literal of the name of this alert>*; }
|
||||
|
||||
The ``alert_type`` is used for the type-checking in ``alert_cast``. It must not collide with
|
||||
any other alert. The built-in alerts in libtorrent will not use alert type IDs greater than
|
||||
``user_alert_id``. When defining your own alert, make sure it's greater than this constant.
|
||||
|
||||
``type()`` is the run-time equivalence of the ``alert_type``.
|
||||
|
||||
The ``message()`` virtual function is expected to construct a useful string representation
|
||||
of the alert and the event or data it represents. Something convenient to put in a log file
|
||||
for instance.
|
||||
|
||||
``clone()`` is used internally to copy alerts. The suggested implementation of simply
|
||||
allocating a new instance as a copy of ``*this`` is all that's expected.
|
||||
|
||||
The static category is required for checking wether or not the category for a specific alert
|
||||
is enabled or not, without instantiating the alert. The ``category`` virtual function is
|
||||
the run-time equivalence.
|
||||
|
||||
The ``what()`` virtual function may simply be a string literal of the class name of
|
||||
your alert.
