Class AbstractOperationHandler

java.lang.Object
org.eclipse.rap.rwt.remote.AbstractOperationHandler
All Implemented Interfaces:
Serializable, OperationHandler
public abstract class AbstractOperationHandler extends Object implements OperationHandler, Serializable
This class provides an empty implementation of the OperationHandler interface, to minimize the effort required to implement this interface.

Subclasses only need to override those methods that are needed to handle the expected operations for the corresponding remote type. Methods that are not overridden will throw an UnsupportedOperationException.

It is recommended to extend this base class rather than to implement the OperationHandler interface itself.

    • handleSet

      public void handleSet(JsonObject properties)
      Description copied from interface: OperationHandler
      Handles a set operation from the remote object. With a set operation, the remote object informs the receiver that one or more properties have changed their values. The implementation of this method must apply the new property values to the target object in a suitable order.
      Specified by:
      handleSet in interface OperationHandler
      Parameters:
      properties - a map with the properties

    • handleCall

      public void handleCall(String method, JsonObject parameters)
      Description copied from interface: OperationHandler
      Handles a call operation from the remote object. With a call operation, the remote object instructs the receiver to call a method on the target object. The method call may be parameterized with the given properties.
      Specified by:
      handleCall in interface OperationHandler
      Parameters:
      method - the name of the method to call
      parameters - the parameters for the method call, may be empty but never null

    • handleNotify

      public void handleNotify(String event, JsonObject properties)
      Description copied from interface: OperationHandler
      Handles a notify operation from the remote object. With a notify operation, the remote object notifies the receiver that an event has occurred. An implementation of this method must notify the corresponding listeners attached to the target object.
      Specified by:
      handleNotify in interface OperationHandler
      Parameters:
      event - the name of the event that occurred
      properties - the event properties, may be empty but never null
