Constructor Details

JMemoryStateBar

public JMemoryStateBar()

Construct a new default memory monitor

Method Details

initGUI

protected void initGUI()

Init the GUI component of the memory monitor

startMonitor

public void startMonitor()

Start the monitoring of the Java Runtime memory. The components of the state bar are updated by a thread at the frequency given by the refresh delay.

See Also:

• stopMonitor()
• setRefreshDelay(long)
• getRefreshDelay()

stopMonitor

public void stopMonitor()

Stop the monitoring of the Java Runtime memory. The monitoring thread is sopped and the components are no more updated.

See Also:

• startMonitor()

setRefreshDelay

public void setRefreshDelay(long delay)

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

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.

See Also:

• getRefreshDelay()

public Icon getGarbageIcon()

Get the icon displayed on the garbage button.

Returns:

the icon used on the garbage button.

setGarbageIcon

public void setGarbageIcon(Icon icon)

Set the icon displayed on the garbage button.

Parameters:

icon - the icon used on the garbage button.

getActiveIcon
