Method Detail

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.

Overrides:

newInstance in class CoordinateElement

getInstance

public static GLCoordinateElement getInstance(State state)

enable

public static void enable(State defaultState)

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:

push in class CoordinateElement

pop

public void pop(State state,
                Element previousTopElement)

Description copied from class: Element

Pops the element, allowing for side effects to occur. Default method does nothing. NOTE that it is not legal to call State.getElement() in the implementation of this method, which is why the previous top element is provided as an argument.

Overrides:

pop in class Element

setElt

public void setElt(FloatBuffer coords)

Description copied from class: CoordinateElement

Sets the coordinate data in this element.

Overrides:

setElt in class CoordinateElement
