Class AbstractOperationHandler

java.lang.Object
  org.eclipse.rap.rwt.remote.AbstractOperationHandler

All Implemented Interfaces:

java.io.Serializable, OperationHandler

public abstract class AbstractOperationHandler
extends java.lang.Object
implements OperationHandler, java.io.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.

2.0

public AbstractOperationHandler()

Method Detail

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

Since:

2.1

handleCall

public void handleCall(java.lang.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

Since:

2.1

handleNotify

public void handleNotify(java.lang.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

Since:

2.1
