Method Detail

getStateIndex

public StateIndex getStateIndex()

Description copied from class: Element

All concrete element subclasses must register themselves with the State in order to reserve a slot, or index, in the state. This method must be overridden to return this slot.

Specified by:

getStateIndex in class Element

newInstance

public Element newInstance()

Description copied from class: Element

Creates a new instance initialized to the default values for the state element. All concrete Element subclasses must implement this operation.

Specified by:

newInstance in class Element

getInstance

public static ColorElement getInstance(State state)

Returns the instance of this element in the passed State.

enable

public static void enable(State defaultState)

Enables this element in the passed state, which should be the default for a given action.

isEnabled

public static boolean isEnabled(State state)

Indicates whether this element is enabled in the given default state for a particular action.

set

public static void set(State state,
                       FloatBuffer colors)

Sets the color data in the passed state.

get

public static FloatBuffer get(State state)

Returns the color data in the passed state.

push

public void push(State state)

Description copied from class: Element

Pushes the element, allowing for side effects to occur. Default method does nothing.

Overrides:
