Method Detail

processAction

public void processAction(ContainerInstance ci,
                          Component component,
                          org.w3c.dom.Element actionElement)

Description copied from interface: ActionProcessor

Notifies the ComponentSynchronizePeer that a client action has occurred.

Specified by:

processAction in interface ActionProcessor

Parameters:

ci - the relevant ContainerInstance

component - the target Component

actionElement - the XML element describing the action (the name and value of the action may be obtained by querying the ACTION_NAME and ACTION_VALUE attribute values.

See Also:

ActionProcessor.processAction(nextapp.echo2.webcontainer.ContainerInstance, nextapp.echo2.app.Component, org.w3c.dom.Element)

processPropertyUpdate

public void processPropertyUpdate(ContainerInstance ci,
                                  Component component,
                                  org.w3c.dom.Element propertyElement)

Description copied from interface: PropertyUpdateProcessor

Notifies the ComponentSynchronizePeer that a client property update has occurred.

Specified by:

processPropertyUpdate in interface PropertyUpdateProcessor

Parameters:

ci - the relevant ContainerInstance

component - the target Component

propertyElement - the XML element describing the property update (the name and value of the changed property may be obtained by querying the PROPERTY_NAME and PROPERTY_VALUE attribute values.

See Also:

PropertyUpdateProcessor.processPropertyUpdate(nextapp.echo2.webcontainer.ContainerInstance, nextapp.echo2.app.Component, org.w3c.dom.Element)

renderHtml

public void renderHtml(RenderingContext rc,
                       org.w3c.dom.Node parent,
                       Component component)

Description copied from class: AbstractEchoPointPeer

This is the rendering method you must implement if you are to use AbstractEchoPointPeer.

Its a simpler wrapper for the standard one but provides some neato setup services that would otherwise be repeated over and over again.

Note the use of RenderingContext object instead of the standard Echo RenderContext as this provides more rich code facilities.

Specified by:

renderHtml in class AbstractEchoPointPeer

Parameters:

rc - - the RenderingContext to use

parent - - the parent Node to put content into

component - - the component in question

See Also:

AbstractEchoPointPeer.renderHtml(echopointng.ui.util.RenderingContext, Node, nextapp.echo2.app.Component)

createInitDirective

protected void createInitDirective(RenderingContext rc,
                                   Component component,
                                   org.w3c.dom.Element itemXML)

renderUpdate

public boolean renderUpdate(RenderContext rc,
                            ServerComponentUpdate update,
                            java.lang.String targetId)

Description copied from class: AbstractEchoPointPeer

This method ends up calling renderUpdateBaseImpl(rc, update, targetId, fullReplace) method with fullReplace as true. In other words by default it does coarse grain replacement of children.

Specified by:

renderUpdate in interface ComponentSynchronizePeer

Overrides:

renderUpdate in class AbstractEchoPointPeer

Parameters:

rc - the relevant RenderContext

update - the ServerComponentUpdate for which this operation is being performed

targetId - the id of the HTML element inside of which the components HTML code should be rendered.

Returns:

true if updates to descendants should NOT be performed

See Also:

AbstractEchoPointPeer.renderUpdate(nextapp.echo2.webcontainer.RenderContext, nextapp.echo2.app.update.ServerComponentUpdate, java.lang.String)

renderDispose

public void renderDispose(RenderContext rc,
                          ServerComponentUpdate update,
                          Component component)

Description copied from class: AbstractEchoPointPeer

Removes any render state that is associated with the component.

Remember to call super.renderDispose() if you overrride this method.

Specified by:

renderDispose in interface ComponentSynchronizePeer

Overrides:

renderDispose in class AbstractEchoPointPeer

Parameters:

rc - the relevant RenderContext

update - the ServerComponentUpdate for which this operation is being performed

See Also:

AbstractEchoPointPeer.renderDispose(nextapp.echo2.webcontainer.RenderContext, nextapp.echo2.app.update.ServerComponentUpdate, nextapp.echo2.app.Component)

createDisposeDirective

protected void createDisposeDirective(ServerMessage serverMessage,
                                      Component component)

createInitDirectiveItem

protected org.w3c.dom.Element createInitDirectiveItem(RenderingContext rc,
                                                      Component component,
                                                      Style fallbackStyle)

getDisplayedDate

protected java.util.Calendar getDisplayedDate(DateChooser dateChooser)

Returns a copy/clone of the selected date using standard semantics.
