Class life.Life 

java.lang.Object

   +----life.Life
public class Life
extends Object
implements Runnable
A Life object generates life. Essentially, a Life object encapsulates a grid of cells, and changes the state of the grid in successive generations according to the rules of the game of Life. To display the life generated by a Life object, use a LifeDisplay object.

See Also:
Grid, LifeDisplay

Variable Index

o CONTINUOUS
Generate life until the user aborts.
o STEP
Generate one generation of life.

Constructor Index

o Life(LifeDisplay)
Creates a new Life with the given LifeDisplay.

Method Index

o generate(int)
Start generating life.
o getAge(int, int)
Get the age of the cell at the specified x-y coordinate.
o getDelay()
Get the delay between frames.
o getDirtyCells()
Return the cells in the grid that have changed since the last generation and therefore need to be repainted.

o setCell(int, int, Grid. Cell)
Copy the age and life status (i.e., living or dead) from the specified cell into the cell at the specified x-y coordinate of the grid.
o setDelay(long)
Set the delay between frames.
o setGeneration(int)
Set the current generation number.
o setGridSize(int, int)
Set the width and height of the grid.
o setMaxAge(int)

o setWraparound(boolean)
Instruct the Life to either use or not use wraparound when counting neighbors.
o stop()
Stop generating life.

Variables
