burlap.visualizer.StateActionRenderLayer

All Implemented Interfaces:

RenderLayer

public abstract class StateActionRenderLayer
extends java.lang.Object
implements RenderLayer

A class for rendering state-action events. This class will maintain the current State and Action to render. Subclasses need to implement the renderStateAction(java.awt.Graphics2D, State, Action, float, float) method.

Method Summary

Modifier and Type	Method and Description
void	clearRenderedStateAction() Sets the State and Action to render to null, which will prevent calls to the method renderStateAction(java.awt.Graphics2D, State, Action, float, float) to be made.
Action	getRenderAction() Returns the Action that is/will be rendered
State	getRenderState() Returns the State that is/will be rendered
void	render(java.awt.Graphics2D g2, float width, float height)
abstract void	renderStateAction(java.awt.Graphics2D g2, State s, Action a, float width, float height) Method to be implemented by subclasses that will render the input state-action to the given graphics context.
void	updateRenderedStateAction(State s, Action a) Updates the State and Action that will be rendered the next time this class draws

Method Detail

getRenderState

public State getRenderState()

Returns the State that is/will be rendered

Returns:

a State

getRenderAction

public Action getRenderAction()

Returns the Action that is/will be rendered

Returns:

a Action

updateRenderedStateAction

public void updateRenderedStateAction(State s,
                                      Action a)

Updates the State and Action that will be rendered the next time this class draws

Parameters:

s - a State to render

a - a Action to render

clearRenderedStateAction

public void clearRenderedStateAction()

Sets the State and Action to render to null, which will prevent calls to the method renderStateAction(java.awt.Graphics2D, State, Action, float, float) to be made.

render

public void render(java.awt.Graphics2D g2,
                   float width,
                   float height)

Specified by:

render in interface RenderLayer

renderStateAction

public abstract void renderStateAction(java.awt.Graphics2D g2,
                                       State s,
                                       Action a,
                                       float width,
                                       float height)

Method to be implemented by subclasses that will render the input state-action to the given graphics context.

Parameters:

g2 - the Graphics2D to which to render

s - the State to render

a - the Action to render

width - the width of the graphics context

height - the height of hte graphics context
