In addition to the level setting, filters are used to provide a psuedo-hierarchical mapping for processing only those events for a given category.

Each logger belongs to a category. By convention these categories map to the fully-qualified class name in which the logger is used. For example, a logger that is logging messages for the mx.rpc.soap.WebService class, uses "mx.rpc.soap.WebService" as the parameter to the Log.getLogger() method call. When messages are sent under this category only those targets that have a filter which matches that category receive notification of those events. Filter expressions can include a wildcard match, indicated with an asterisk. The wildcard must be the right-most character in the expression. For example: rpc*, mx.*, or *. If an invalid expression is specified, a InvalidFilterError is thrown. If null or [] is specified, the filters are set to the default of ["*"].

For example:

               var traceLogger:ILoggingTarget = new TraceTarget();
               traceLogger.filters = ["mx.rpc.*", "mx.messaging.*"];
               Log.addTarget(traceLogger);

id

proprietà

id:String [sola lettura]

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

Provides access to the id of this target. The id is assigned at runtime by the mxml compiler if used as an mxml tag, or internally if used within a script block

public function get id():String

level

proprietà

level:int

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

Provides access to the level this target is currently set at. Value values are:

LogEventLevel.FATAL (1000) designates events that are very harmful and will eventually lead to application failure
LogEventLevel.ERROR (8) designates error events that might still allow the application to continue running.
LogEventLevel.WARN (6) designates events that could be harmful to the application operation
LogEventLevel.INFO (4) designates informational messages that highlight the progress of the application at coarse-grained level.
LogEventLevel.DEBUG (2) designates informational level messages that are fine grained and most helpful when debugging an application.
LogEventLevel.ALL (0) intended to force a target to process all messages.

Constructor.

Descrizione dei metodi

addLogger

()

metodo

public function addLogger(logger:ILogger):void

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

Sets up this target with the specified logger. This allows this target to receive log events from the specified logger.

Parametri

logger:ILogger — The ILogger that this target should listen to.

initialized

()

metodo

public function initialized(document:Object, id:String):void

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

Called after the implementing object has been created and all properties specified on the tag have been assigned.

Parametri

	`document:Object` — MXML document that created this object.

	`id:String` — Used by the document to refer to this object. If the object is a deep property on the document, id is null.

logEvent

()

metodo

public function logEvent(event:LogEvent):void

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

This method handles a LogEvent from an associated logger. A target uses this method to translate the event into the appropriate format for transmission, storage, or display. This method will be called only if the event's level is in range of the target's level.

NOTE: Descendants must override this method to make it useful.

Parametri

event:LogEvent — An event from an associated logger.

removeLogger

()

metodo

public function removeLogger(logger:ILogger):void

Versione linguaggio:

ActionScript 3.0

Versione prodotto:

Flex 3

Versioni runtime:

Flash Player 9, AIR 1.1

Stops this target from receiving events from the specified logger.

Parametri

logger:ILogger — The ILogger that this target should ignore.
