Enables tracing for all instances of this class. If the argument is true then all log messages are recorded, otherwise only the informative, warning and error messages are recorded.

Parameters:

aClassTraceOn - if true then all log messages are recorded, otherwise only the informative, warning and error messages are recorded.

setTraceOn

public void setTraceOn(boolean aTraceOn)

Deprecated. This method has been deprecated. It is recommended to use the standard Java logging framework directly.

Enables tracing for this class instance. Calling this method with either true or false as argument automatically turns off tracing for all other class instances for which setTraceOn has not been called. If the argument is false then only the informative, warning and error log messages are recorded.

Parameters:

aTraceOn - if true then all log messages are recorded for this instance. If false, then only the informative, warning and error log messages are recorded.

isTraceOn

public boolean isTraceOn()

Deprecated. This method has been deprecated. It is recommended to use the standard Java logging framework directly.

Returns true if tracing is enabled for this class.

Returns:

true if tracing is enabled for this class, false otherwise.

addStatusListener

public void addStatusListener(ILcdStatusListener<T> aStatusListener)

Adds a status listener that will listen to the events fired using fireStatusEvent(com.luciad.util.TLcdStatusEvent<T>).

Parameters:

aStatusListener - a listener for all events fired by this instance. The listener must not be null.

Throws:

NullPointerException - when the listener passed is null.

removeStatusListener

public void removeStatusListener(ILcdStatusListener<T> aStatusListener)

Removes a status listener that listened to the events fired using this instances fireStatusEvent(com.luciad.util.TLcdStatusEvent<T>).

Parameters:

aStatusListener - a listener for all events fired by this instance.

fireStatusEvent

public void fireStatusEvent(TLcdStatusEvent<T> aStatusEvent)

Fires a status event, thus notifying all listeners that were added using addStatusListener(com.luciad.util.ILcdStatusListener<T>).

Parameters:

aStatusEvent - the status event to pass to all listeners.

getStatusListeners

public ILcdStatusListener<T>[] getStatusListeners()

Returns an array containing all listeners that were added using addStatusListener(com.luciad.util.ILcdStatusListener<T>). If no listeners were added, an empty array will be returned.

Returns:

an array containing all listeners that were added using addStatusListener(com.luciad.util.ILcdStatusListener<T>).
