Static methods:

• public static void set_name_by_id (uint tag, string? name)
  Sets the name of a source using its ID.
• public static bool remove (uint id)
  Removes the source with the given id from the default main context.
• public static bool remove_by_funcs_user_data (void* user_data)
  Removes a source from the default main loop context given the source functions and user data.
• public static bool remove_by_user_data (void* user_data)
  Removes a source from the default main loop context given the user data for the callback.

Creation methods:

• protected Source ()
  Creates a new SocketSource structure.

Methods:

• public void set_funcs (SourceFuncs funcs)
  Sets the source functions (can be used to override default implementations) of an unattached source.
• public uint attach (MainContext? context)
  Adds a SocketSource to a context so that it will be executed within that context.
• public void destroy ()
  Removes a source from its MainContext, if any, and mark it as destroyed.
• public bool is_destroyed ()
  Returns whether this has been destroyed.
• public void set_priority (int priority)
  Sets the priority of a source.
• public int get_priority ()
  Gets the priority of a source.
• public void set_can_recurse (bool can_recurse)
  Sets whether a source can be called recursively.
• public bool get_can_recurse ()
  Checks whether a source is allowed to be called recursively.
• public uint get_id ()
  Returns the numeric ID for a particular source.
• public unowned string? get_name ()
  Gets a name for the source, used in debugging and profiling.
• public void set_name (string? name)
  Sets a name for the source, used in debugging and profiling.
• public weak MainContext get_context ()
  Gets the MainContext with which the source is associated.
• public void set_callback (owned SourceFunc func)
• public void set_callback_indirect (void* callback_data, SourceCallbackFuncs callback_funcs)
  Sets the callback function storing the data as a refcounted callback "object".
• public void* add_unix_fd (int fd, IOCondition events)
  Monitors fd for the IO events in events.
• public void remove_unix_fd (void* tag)
  Reverses the effect of a previous call to add_unix_fd.
• public void modify_unix_fd (void* tag, IOCondition new_events)
  Updates the event mask to watch for the fd identified by tag .
• public IOCondition query_unix_fd (void* tag)
  Queries the events reported for the fd corresponding to tag on this during the last poll.
• public void add_poll (ref PollFD fd)
  Adds a file descriptor to the set of file descriptors polled for this source.
• public void remove_poll (ref PollFD fd)
  Removes a file descriptor from the set of file descriptors polled for this source.
• public void add_child_source (Source child_source)
  Adds child_source to this as a "polled" source; when this is added to a MainContext, child_source will be automatically added with the same priority, when child_source is triggered, it will cause this to dispatch (in addition to calling its own callback), and when this is destroyed, it will destroy child_source as well.
• public void remove_child_source (Source child_source)
  Detaches child_source from this and destroys it.
• public int64 get_time ()
  Gets the time to be used when checking this source.
• public void get_current_time (out TimeVal timeval)
  This function ignores this and is otherwise the same as TimeVal.
• public void set_ready_time (int64 ready_time)
  Sets a SocketSource to be dispatched when the given monotonic time is reached (or passed).
• public int64 get_ready_time ()
  Gets the "ready time" of this, as set by set_ready_time.
• protected abstract bool prepare (out int timeout_)
• protected abstract bool check ()
• protected abstract bool dispatch (SourceFunc _callback)
