init
protected void init()Description copied from class:
AbstractConnectorCalled when the connector has been initialized. Override this method to perform initialization of the connector.
Overrides:
initin classAbstractConnector
-
getState
public JavaScriptExtensionState getState()Description copied from class:
AbstractConnectorReturns the shared state object for this connector. Override this method to define the shared state type for your connector.
Specified by:
getStatein interfaceServerConnectorOverrides:
getStatein classAbstractRendererConnector<Object>Returns:
the current shared state (never null)
-
createRenderer
protected Renderer<Object> createRenderer()Description copied from class:
AbstractRendererConnectorCreates a new Renderer instance associated with this renderer connector.
You should typically not override this method since the framework by default generates an implementation that uses
GWT.create(Class)to create a renderer of the same type as returned by the most specific override ofAbstractRendererConnector.getRenderer(). If you do override the method, you can't callsuper.createRenderer()since the metadata needed for that implementation is not generated if there's an override of the method.Overrides:
createRendererin classAbstractRendererConnector<Object>Returns:
a new renderer to be used with this connector

decode
public Object decode(elemental.json.JsonValue value)Description copied from class:
AbstractRendererConnectorDecodes the given JSON value into a value of type T so it can be passed to the
renderer.Overrides:
