shader

Constructor Summary

ShaderElement()

Method Summary

static void	enable(State defaultState) Enables this element in the passed state, which should be the default for a given action.
static ShaderNode	get(State state) Returns the current shader in the state.
static ShaderElement	getInstance(State state) Returns the instance of this element in the passed State.
StateIndex	getStateIndex() All concrete element subclasses must register themselves with the State in order to reserve a slot, or index, in the state.
static boolean	isEnabled(State state) Indicates whether this element is enabled in the given default state for a particular action.
Element	newInstance() Creates a new instance initialized to the default values for the state element.
void	push(State state) Pushes the element, allowing for side effects to occur.
static void	set(State state, ShaderNode shader) Sets the shader in the given state.
void	setElt(ShaderNode shader) Sets the shader in this element.

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 ShaderElement 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,
                       ShaderNode shader)

Sets the shader in the given state.

get

public static ShaderNode get(State state)

Returns the current shader in the 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:

push in class Element

setElt

public void setElt(ShaderNode shader)

Sets the shader in this element.
