HideOperation

public HideOperation(NodeContentPart node,
                     boolean isHidden)

Constructs a new HideOperation that will show or hide the given NodeContentPart depending on the isHidden flag. If the node is currently hidden (as indicated by the flag being set to true), then the node will be shown, otherwise it will be hidden upon execution.

Parameters:

node - The NodeContentPart to show/hide.

isHidden - true if the NodeContentPart should be shown, otherwise false.

Method Detail

hide

public static HideOperation hide(NodeContentPart toHide)

Constructs a new HideOperation that will hide the given NodeContentPart upon execution.

Parameters:

toHide - The NodeContentPart to hide.

Returns:

The new HideOperation that will hide the given NodeContentPart upon execution.

show

public static HideOperation show(NodeContentPart toShow)

Constructs a new HideOperation that will show the given NodeContentPart upon execution.

Parameters:

toShow - The NodeContentPart to show.

Returns:

The new HideOperation that will show the given NodeContentPart upon execution.
