Property Detail

LogLogger

()

Constructor

public function LogLogger(category:String)

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Constructor.

Parameters

category:String — The category for which this log sends messages.

Method Detail

debug

()

method

public function debug(msg:String, ... rest):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Logs the specified data using the LogEventLevel.DEBUG level. LogEventLevel.DEBUG designates informational level messages that are fine grained and most helpful when debugging an application.

The string specified for logging can contain braces with an index indicating which additional parameter should be inserted into the string before it is logged. For example "the first additional parameter was {0} the second was {1}" will be translated into "the first additional parameter was 10 the second was 15" when called with 10 and 15 as parameters.

Parameters

	`msg:String` — The information to log. This string can contain special marker characters of the form {x}, where x is a zero based index that will be replaced with the additional parameters found at that index if specified.

	`... rest` — Additional parameters that can be subsituted in the str parameter at each "{`x`}" location, where `x` is an integer (zero based) index value into the Array of values specified.

error

()

method

public function error(msg:String, ... rest):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Logs the specified data using the LogEventLevel.ERROR level. LogEventLevel.ERROR designates error events that might still allow the application to continue running.

Parameters

	`msg:String` — The information to log. This String can contain special marker characters of the form {x}, where x is a zero based index that will be replaced with the additional parameters found at that index if specified.

	`... rest` — Additional parameters that can be subsituted in the str parameter at each "{`x`}" location, where `x` is an integer (zero based) index value into the Array of values specified.

fatal

()

method

public function fatal(msg:String, ... rest):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Logs the specified data using the LogEventLevel.FATAL level. LogEventLevel.FATAL designates events that are very harmful and will eventually lead to application failure

Parameters

	`msg:String` — The information to log. This String can contain special marker characters of the form {x}, where x is a zero based index that will be replaced with the additional parameters found at that index if specified.

	`... rest` — Additional parameters that can be subsituted in the str parameter at each "{`x`}" location, where `x` is an integer (zero based) index value into the Array of values specified.

info

()

method

public function info(msg:String, ... rest):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Logs the specified data using the LogEvent.INFO level. LogEventLevel.INFO designates informational messages that highlight the progress of the application at coarse-grained level.

Parameters

	`msg:String` — The information to log. This String can contain special marker characters of the form {x}, where x is a zero based index that will be replaced with the additional parameters found at that index if specified.

	`... rest` — Additional parameters that can be subsituted in the str parameter at each "{`x`}" location, where `x` is an integer (zero based) index value into the Array of values specified.

log

()

method

public function log(level:int, msg:String, ... rest):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Logs the specified data at the given level.

The String specified for logging can contain braces with an index indicating which additional parameter should be inserted into the String before it is logged. For example "the first additional parameter was {0} the second was {1}" is translated into "the first additional parameter was 10 the second was 15" when called with 10 and 15 as parameters.

Parameters

	`level:int` — The level this information should be logged at. Valid values are: `LogEventLevel.FATAL` designates events that are very harmful and will eventually lead to application failure `LogEventLevel.ERROR` designates error events that might still allow the application to continue running. `LogEventLevel.WARN` designates events that could be harmful to the application operation `LogEventLevel.INFO` designates informational messages that highlight the progress of the application at coarse-grained level. `LogEventLevel.DEBUG` designates informational level messages that are fine grained and most helpful when debugging an application.

	`msg:String` — The information to log. This String can contain special marker characters of the form {x}, where x is a zero based index that will be replaced with the additional parameters found at that index if specified.

	`... rest` — Additional parameters that can be subsituted in the str parameter at each "{`x`}" location, where `x` is an integer (zero based) index value into the Array of values specified.

warn

()

method

public function warn(msg:String, ... rest):void

Language Version:

ActionScript 3.0

Product Version:

Flex 3

Runtime Versions:

Flash Player 9, AIR 1.1

Logs the specified data using the LogEventLevel.WARN level. LogEventLevel.WARN designates events that could be harmful to the application operation.

Parameters

	`msg:String` — The information to log. This String can contain special marker characters of the form {x}, where x is a zero based index that will be replaced with the additional parameters found at that index if specified.

	`... rest` — Aadditional parameters that can be subsituted in the str parameter at each "{`x`}" location, where `x` is an integer (zero based) index value into the Array of values specified.
