InheritanceDataGridAppender Inheritance mx.collections.ArrayCollection
ImplementsLoggerListener

The DataGridAppender is a simple LoggerListener implementation that extends the ArrayCollection class. It writes log lines received from the Logger to which it was added on its internal structure. As any ArrayCollection subclass it can be set as dataProvider property to any instance of ListBase or subclasses to show the log on a visual widget.
The following fields are generated on the model for each log line: A suitable widget to display the log lines has to be provided by application code.
Example usage:

     var gridAppender:DataGridAppender = new DataGridAppender(Logger.DEBUG,300);
     myLogView.dataProvider = gridAppender;
     var logger:Logger = Logger.getLogger("com.lightstreamer.as_client.LSClient");
     logger.addLoggerListener(gridAppender);

where "myLogView" is a DataGrid which defines a dataField for each model field.

public function DataGridAppender(level:uint = 0, maxLines:uint = 250)

Constructor for DataGridAppender.

Parameters
level:uint (default = 0) — the threshold level at which the DataGridAppender is created. It should be one of DEBUG INFO WARN ERROR.
 
maxLines:uint (default = 250) — the maximum number of log lines to be stored on the internal structure. Once this limit is reached, older lines are deleted.

getLevel()method 
public function getLevel():uint

Returns
uint — the level of the listener instance. It should be one of DEBUG INFO WARN ERROR.
log()method 
public function log(loggerName:String, level:String, mex:String):void

Receive log messages from the Logger instances to which it was added and from their sons.

Parameters
loggerName:String — the name of the Logger instance that has published the message.
 
level:String — the string version of the level of the message.
 
mex:String — the message.
setLevel()method 
public function setLevel(level:uint):void

Change the threshold level for the listener.

Parameters
level:uint — the new threshold level. It should be one of DEBUG INFO WARN ERROR.
