Method Detail

receiveLogEvent

public boolean receiveLogEvent(LogEvent le)

Receive a log event. Override in subclasses with something useful. The default implementation does nothing and just tests whether the passed LogEvent would have been eccepted.

Specified by:

receiveLogEvent in interface LogListener

Parameters:

le -

Returns:

See Also:

LogListener.receiveLogEvent(de.infinityloop.util.log.LogEvent)

addedTo

public void addedTo(LogBroadcaster le)

Called when this object is successfully attached to a LogPublisher.

Specified by:

addedTo in interface LogListener

Parameters:

le -

See Also:

LogListener.addedTo(de.infinityloop.util.log.LogBroadcaster)

removedFrom

public void removedFrom(LogBroadcaster le)

Gets called when we were removed from a LogBroadcaster successfully.

Specified by:

removedFrom in interface LogListener

Parameters:

le -

See Also:

LogListener.removedFrom(de.infinityloop.util.log.LogBroadcaster)

unregisterFromAll

public void unregisterFromAll(LogListener self)

This method unregisters this LogListener from all LogBroadcasters it is registered with. Use this to break any links and make this object disposable to the GC.

getFilter

public final de.infinityloop.util.log.helpers.LogEventFilter getFilter()

Returns:

the filter

getFilterspec

public final java.lang.String getFilterspec()

Returns:

the filterspec String

setFilter

public final void setFilter(de.infinityloop.util.log.helpers.LogEventFilter filter)

Parameters:

filter - the filter to set

toString

public java.lang.String toString()

instance info for debugging

Overrides:

toString in class java.lang.Object

Returns:

See Also:

Object.toString()

setName

public final void setName(java.lang.String name)

Parameters:

name - the name to set
