public void onMessage(java.lang.String type,
                      com.fasterxml.jackson.databind.JsonNode data,
                      JsonRequest request)

Description copied from class: JsonSocketService

Handle an inbound message.

Specified by:

onMessage in class JsonSocketService<JsonSchemaHttpService>

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:

java.io.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(java.lang.String type,
                   com.fasterxml.jackson.databind.JsonNode data,
                   JsonRequest request)
            throws java.io.IOException,
                   JmriException,
                   JsonException

Description copied from class: JsonSocketService

Specified by:

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:

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
