JavaScriptRendererConnector

public JavaScriptRendererConnector()

Method Detail

init

protected void init()

Description copied from class: AbstractConnector

Called when the connector has been initialized. Override this method to perform initialization of the connector.

Overrides:

init in class AbstractConnector

getState

public JavaScriptExtensionState getState()

Description copied from class: AbstractConnector

Returns the shared state object for this connector. Override this method to define the shared state type for your connector.

Specified by:

getState in interface ServerConnector

Overrides:

getState in class AbstractRendererConnector<Object>

Returns:

the current shared state (never null)

createRenderer

protected Renderer<Object> createRenderer()

Description copied from class: AbstractRendererConnector

Creates 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 of AbstractRendererConnector.getRenderer(). If you do override the method, you can't call super.createRenderer() since the metadata needed for that implementation is not generated if there's an override of the method.

Overrides:

createRenderer in class AbstractRendererConnector<Object>

Returns:

a new renderer to be used with this connector

decode

public Object decode(JsonValue value)

Description copied from class: AbstractRendererConnector

Decodes the given JSON value into a value of type T so it can be passed to the renderer.

Overrides:

decode in class AbstractRendererConnector<Object>

Parameters:

value - the value to decode

Returns:

the decoded value of value

onUnregister

public void onUnregister()

Description copied from interface: ServerConnector

Event called when connector has been unregistered.

Specified by:

onUnregister in interface ServerConnector

Overrides:

onUnregister in class AbstractConnector

getJavascriptConnectorHelper

public JavaScriptConnectorHelper getJavascriptConnectorHelper()

Specified by:

getJavascriptConnectorHelper in interface HasJavaScriptConnectorHelper
