Constructor Detail

JMemoryStateBar

public JMemoryStateBar()

Construct a new default memory monitor

Method Detail

initGUI

protected void initGUI()

Init the GUI component of the memory monitor

startMonitor

public void startMonitor()

Parameters:

delay - the delay of time.

See Also:

getRefreshDelay()

getRefreshDelay

public long getRefreshDelay()

Set the delay of time in milliseconds between two refreshes of the memory state bar.

Returns:

the delay of time.
