Detailed Description

A simple applet class to demonstrate a sort algorithm. You can specify a sorting algorithm using the "alg" attribute. When you click on the applet, a thread is forked which animates the sorting algorithm.

package

Fill the array with random numbers from 0..n-1.

start()

void SortItem.start

Definition at line 157 of file SortItem.java.

startSort()

synchronized void SortItem.startSort ( )

private

For a Thread to actually do the sorting. This routine makes sure we do not simultaneously start several sorts if the user repeatedly clicks on the sort item. It needs to be synchronized with the stop() method because they both manipulate the common kicker variable.

Definition at line 285 of file SortItem.java.

stop()

synchronized void SortItem.stop

(

)

Stop the applet. Kill any sorting algorithm that is still sorting.

Definition at line 267 of file SortItem.java.

Here is the call graph for this function:

update()

void SortItem.update

(
