| bool add_listener (XrlPFListener* listener)
| add_listener |
Add a protocol family listener. When XRLs are registered through XrlRouter::finalize() they will register support for each protocol family listener added.
| void finalize ()
| finalize |
Start registration of XRLs that have been registered via add_handler with the Finder.
Reimplemented from XrlCmdMap.
| bool finalized ()
| finalized |
[const]
Returns: true when XRLs
| bool connected ()
| connected |
[const]
Returns: true if instance has established a connection to the Finder.
| bool connect_failed ()
| connect_failed |
[const]
Returns: true if instance has encountered a connection error to the Finder.
| bool ready ()
| ready |
[const]
Returns: true if instance has established a connection to the Finder, registered own XRLs, and should be considered operational.
| bool failed ()
| failed |
[const]
Returns: true if instance has experienced an unrecoverable error.
| bool send (const Xrl& xrl, const XrlCallback& cb)
| send |
Send XRL.
Parameters:
| xrl | XRL to be sent. |
| cb | callback to be dispatched with XRL result and return values. |
Returns: true if XRL accepted for sending, false if insufficient resources are available.
Reimplemented from XrlSender.
| bool pending ()
| pending |
[const]
Returns: true if at least one XrlRouter::send() call is still pending a result.
Reimplemented from XrlSender.
| bool add_handler (const string& cmd, const XrlRecvCallback& rcb)
| add_handler |
Add an XRL method handler.
Parameters:
| cmd | XRL method path name. |
| rcb | callback to be dispatched when XRL method is received for invocation. |
Reimplemented from XrlCmdMap.
| EventLoop& eventloop ()
| eventloop |
Returns: EventLoop used by XrlRouter instance.

| void finder_connect_event ()
| finder_connect_event |
[protected virtual]
Called when Finder connection is established.
Reimplemented from FinderClientObserver.
| void finder_disconnect_event ()
| finder_disconnect_event |
[protected virtual]
Called when Finder disconnect occurs.
Reimplemented from FinderClientObserver.
| void finder_ready_event (const string& tgt_name)
| finder_ready_event |
[protected virtual]
Called when an Xrl Target becomes visible to other processes. Implementers of this method should check tgt_name corresponds to the XrlRouter::instance_name as other targets within same process may cause this method to be invoked.
Default implementation is a no-op.
Parameters:
| tgt_name | name of Xrl Target becoming ready. |
Reimplemented from FinderClientObserver.

const XrlArgs& inputs,
XrlArgs& outputs)
| dispatch_xrl |
[protected const]
Reimplemented from XrlDispatcher.
| void resolve_callback (const XrlError& e,
const FinderDBEntry* dbe,
XrlRouterDispatchState* ds)
| resolve_callback |
[protected]
Resolve callback (slow path).
Called with results from asynchronous FinderClient Xrl queries.
| void send_callback (const XrlError& e,
XrlArgs* reply,
XrlPFSender* sender,
XrlCallback user_callback)
| send_callback |
[protected]
| bool send_resolved (const Xrl& xrl,
const FinderDBEntry* dbe,
const XrlCallback& dispatch_cb,
bool direct_call)
| send_resolved |
[protected]
Choose appropriate XrlPFSender and execute Xrl dispatch.
Returns: true on success, false otherwise.
