public class Behavior

extends java.lang.Object

An image generator with state entirely parameterized by time and a pixel function.

Constructor Summary

Behavior(ELExpression e, int width, int height, int numGenerations)

Behavior(GeneticParameters gp, int width, int height)

Method Summary

void	environmentChanged() Invoke to tell the behavior that its environment has been mutated and it should redraw if necessary.
void	evaluate()
void	evaluate(ELEnvironment environment) Evaluates the expression.
Behavior	free() Deallocates resources consumed by this behavior.
boolean	isBoring() Returns true if this behavior is boring.
boolean	sameExpression(Behavior b) Returns true if both behaviors share an expression.

Field Detail

expression

ELExpression expression

currentValue

ELMatrix currentValue

java.lang.String expressionCode

Constructor Detail

Behavior

public Behavior(GeneticParameters gp,
                int width,
                int height)

Parameters:

gp - The parameters that should be used to generate the initial expression.

Behavior

public Behavior(ELExpression e,
                int width,
                int height,
                int numGenerations)

Method Detail

setRandomExpression

public void setRandomExpression(GeneticParameters gp)

Sets this behavior to a new, non-boring expression.

setExpression

public void setExpression(ELExpression e)

isBoring

public boolean isBoring()

Returns true if this behavior is boring.

free

public Behavior free()

Deallocates resources consumed by this behavior.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

evaluate

public void evaluate()

evaluate

public void evaluate(ELEnvironment environment)

Evaluates the expression.

sameExpression

public boolean sameExpression(Behavior b)

Returns true if both behaviors share an expression.

environmentChanged

public void environmentChanged()

Invoke to tell the behavior that its environment has been mutated and it should redraw if necessary. This will automatically trigger re-evaluation and redraw on the invoking thread.
