jsonrpc_client_error_quark ()

GQuark
jsonrpc_client_error_quark (void);

jsonrpc_client_new ()

JsonrpcClient *
jsonrpc_client_new (GIOStream *io_stream);

Creates a new JsonrpcClient instance.

If you want to communicate with a process using stdin/stdout, consider using GSubprocess to launch the process and create a GSimpleIOStream using the g_subprocess_get_stdin_pipe() and g_subprocess_get_stdout_pipe().

jsonrpc_client_get_use_gvariant ()

gboolean
jsonrpc_client_get_use_gvariant (JsonrpcClient *self);

Gets the “use-gvariant” property.

Indicates if GVariant is being used to communicate with the peer.

Since: 3.26

jsonrpc_client_set_use_gvariant ()

void
jsonrpc_client_set_use_gvariant (JsonrpcClient *self,
                                 gboolean use_gvariant);

Sets the “use-gvariant” property.

This function sets if GVariant should be used to communicate with the peer. Doing so can allow for more efficient communication by avoiding expensive parsing overhead and memory allocations. However, it requires that the peer also supports GVariant encoding.

jsonrpc_client_close ()

gboolean
jsonrpc_client_close (JsonrpcClient *self,
                      GCancellable *cancellable,
                      GError **error);

Closes the underlying streams and cancels any inflight operations of the JsonrpcClient. This is important to call when you are done with the client so that any outstanding operations that have caused self to hold additional references are cancelled.

Failure to call this method results in a leak of JsonrpcClient.

Since: 3.26

jsonrpc_client_close_async ()

void
jsonrpc_client_close_async (JsonrpcClient *self,

gboolean
jsonrpc_client_call (JsonrpcClient *self,
                     const gchar *method,

                     GVariant **return_value,
                     GError **error);

Synchronously calls method with params on the remote peer.

once a reply has been received, or failure, this function will return. If successful, return_value will be set with the reslut field of the response.

If params is floating then this function consumes the reference.

                                   gpointer user_data);

Asynchronously calls method with params on the remote peer.

Upon completion or failure, callback is executed and it should call jsonrpc_client_call_finish() to complete the request and release any memory held.

This function is similar to jsonrpc_client_call_async() except that it allows the caller to get the id of the command which might be useful in systems where you can cancel the operation (such as the Language Server Protocol).

If params is floating, the floating reference is consumed.

                                gpointer user_data);

Asynchronously calls method with params on the remote peer. This function will not wait or expect a reply from the peer.

This function is useful when the caller wants to be notified that the bytes have been delivered to the underlying stream. This does not indicate that the peer has received them.

If params is floating then the reference is consumed.

The “io-stream” property

  “io-stream”                GIOStream *

The "io-stream" property is the GIOStream to use for communicating with a JSON-RPC peer.

Owner: JsonrpcClient

Flags: Write / Construct Only

Since: 3.26

The “use-gvariant” property

  “use-gvariant”             gboolean

The "use-gvariant" property denotes if GVariant should be used to communicate with the peer instead of JSON. You should only set this if you know the peer is also a Jsonrpc-GLib based client.

Setting this property allows the peers to communicate using GVariant instead of JSON. This means that we can access the messages without expensive memory allocations and parsing costs associated with JSON. GVariant is much more optimal for memory-bassed message passing.

Owner: JsonrpcClient

Flags: Read / Write

Default value: FALSE

The “failed” signal

void
user_function (JsonrpcClient *jsonrpcclient,
               gpointer       user_data)

The "failed" signal is called when the client has failed communication or the connection has been knowingly closed.

Flags: Run Last

Since: 3.28

The “handle-call” signal

gboolean
user_function (JsonrpcClient *self,
               gchar         *method,
               GVariant      *id,
               GVariant      *params,
               gpointer       user_data)

This signal is emitted when an RPC has been received from the peer we are connected to. Return TRUE if you have handled this message, even asynchronously. If no handler has returned TRUE an error will be synthesized.

If you handle the message, you are responsible for replying to the peer in a timely manner using jsonrpc_client_reply() or jsonrpc_client_reply_async().

Additionally, since 3.28 you may connect to the "detail" of this signal to handle a specific method call. Use the method name as the detail of the signal.

Flags: Has Details

The “notification” signal

void
user_function (JsonrpcClient *self,

               GVariant      *params,
               gpointer       user_data)

This signal is emitted when a notification has been received from a peer. Unlike “handle-call”, this does not have an "id" parameter because notifications do not have ids. They do not round trip.

Flags: Has Details
