Method Detail

cancel

public void cancel()

Since compare() connects to the server, the comparison is time consuming. Once called, Arrays.sort() invokes compare() for every array entry, even if the user cancelled the SwingWorker which called Arrays.sort(). To reduce resource consumption this method sets a flag which tells the comparator to abort the comparison. This is done by returning a default value for every unsorted entry.

compare

public int compare(Sirius.server.middleware.types.Node o1,
                   Sirius.server.middleware.types.Node o2)

Specified by:

compare in interface Comparator<Sirius.server.middleware.types.Node>

getConnectionContext

public final de.cismet.connectioncontext.ConnectionContext getConnectionContext()

Specified by:

getConnectionContext in interface de.cismet.connectioncontext.ConnectionContextProvider
