Method Detail

init

protected void init(boolean pushed)

Initializes the Node. It needs to be invoked from the constructor

updateState

public abstract void updateState(boolean initial)

Updates the state of the Node. The children should be removed and recreated.

Parameters:

initial - - If this is the first update

getUpdaterId

public abstract java.lang.String getUpdaterId(java.lang.String requestId)

Returns the id, that identifies the element. It can depend on the request, but it might not use it. It should not change e.g. when we follow a redirect as it is used in internal structures to identify the element.

getUpdaterType

public abstract java.lang.String getUpdaterType()

Returns the type of the client-side updater.

dispose

public abstract void dispose()

Disposes the Node
