Class JsonNamedBeanSocketService<T extends NamedBean,H extends JsonNamedBeanHttpService<T>>

java.lang.Object

jmri.server.json.JsonSocketService<H>

jmri.server.json.JsonNamedBeanSocketService<T,H>

Type Parameters:

T - the NamedBean class supported by this service

H - the supporting JsonNamedBeanHttpService class

Direct Known Subclasses:

JsonBlockSocketService, JsonIdTagSocketService, JsonLightSocketService, JsonMemorySocketService, JsonOblockSocketService, JsonReporterSocketService, JsonRouteSocketService, JsonSensorSocketService, JsonSignalMastSocketService, JsonTurnoutSocketService

public class JsonNamedBeanSocketService<T extends NamedBean,H extends JsonNamedBeanHttpService<T>>
extends JsonSocketService<H>

Abstract implementation of JsonSocketService with specific support for NamedBean objects. Note that services requiring support for multiple classes of NamedBean cannot extend this class.

JsonNamedBeanSocketService

public JsonNamedBeanSocketService(JsonConnection connection, H service)

Method Details

onMessage

public void onMessage(String type, com.fasterxml.jackson.databind.JsonNode data, JsonRequest request) throws IOException, JmriException, JsonException

Description copied from class: JsonSocketService

Handle an inbound message.

Specified by:

onMessage in class JsonSocketService<H extends JsonNamedBeanHttpService<T>>

Parameters:

type - The service type; if the implementing service responds to multiple types, it will need to use this to handle data correctly

data - JSON data; the contents of this will depend on the implementing service

request - The JSON request

Throws:

IOException - Thrown if the service cannot send a response; this will cause the JSON Server to close its connection to the client if open

JmriException - Thrown if the request cannot be handled; throwing this will cause the JSON Server to pass a 500 UnsupportedOperation message to the client

JsonException - Thrown if the service needs to pass an error message back to the client

onList

public void onList(String type, com.fasterxml.jackson.databind.JsonNode data, JsonRequest request) throws IOException, JmriException, JsonException

Description copied from class: JsonSocketService

Handle a request for a list of objects. Note that this should not create listeners for items in the list, but should only create listeners for the object providing the list, if applicable.

Specified by:

onList in class JsonSocketService<H extends JsonNamedBeanHttpService<T>>

Parameters:

type - The service type; if the implementing service responds to multiple types, it will need to use this to handle data correctly

data - JSON data; the contents of this will depend on the implementing service

request - The JSON request

Throws:

IOException - Thrown if the service cannot send a response; this will cause the JSON Server to close its connection to the client if open

JmriException - Thrown if the request cannot be handled; throwing this will cause the JSON Server to pass a 500 UnsupportedOperation message to the client

JsonException - If the service needs to pass an error message back to the client; implementing services may throw a JsonException with code 400 and the localized message "UnlistableService" to indicate that type should not be listed

onClose

public void onClose()

Description copied from class: JsonSocketService

Perform any teardown required when closing a connection.

Specified by:

onClose in class JsonSocketService<H extends JsonNamedBeanHttpService<T>>
