Method Detail

init

public void init(java.io.PrintWriter out,
                 java.lang.String tag,
                 Logger.LEVEL level)
          throws SystemException

Initialize the LoggerWriter with a Writer and a prefix ID. The prefix ID will be overridden by a conduit ID, if a PushDrain tries to initialize this.
You cannot call this more than once.

Parameters:

out - A writer. The implementation doesn't care what kind. If the Logger type is set as reliable, then every write will be flushed.

tag - A tag for the line.

level - The logging level. Note that the debug methods will override any value passed here.

Throws:

SystemException

init

public void init(Logger logger,
                 java.lang.String tag,
                 Logger.LEVEL level)
          throws SystemException

Initialize the LoggerWriter with a Writer and a prefix ID. The prefix ID will be overridden by a conduit ID, if a PushDrain tries to initialize this.
You cannot call this more than once.

Parameters:

logger - A logger where to post. The implementation doesn't care what kind. If the Logger type is set as reliable, then every write will be flushed.

tag - A tag for the line.

level - The logging level. Note that the debug methods will override any value passed here.

Throws:

SystemException

clone

public CommandLogger clone(java.lang.String tag)
                    throws SystemException

Create a clone of this logger, but with a new tag. It'll log to the same place as the original, but the tag will be different. All the methods (like level) will be independent. It must be init'd already..

Parameters:

tag - A tag for the line.

Returns:

the clone.

Throws:

SystemException

post

public void post(java.lang.String message)
          throws ThingsException

Post as a message.

Specified by:

post in interface StringPoster

Parameters:

message - String to post

Throws:

ThingsException

postit

public void postit(java.lang.String message)

Post as a message. Best effort. Ignore errors.

Specified by:

postit in interface StringPoster

Parameters:

message - String to post

setLevel

public void setLevel(Logger.LEVEL newLevel)

This will set the level of entries that will pass. It starts at whatever the implementation sets during construction.

Specified by:

setLevel in interface Logger

Parameters:

newLevel - the new level.

getLevel

public Logger.LEVEL getLevel()

This will get the level of entries that will pass. It starts at whatever the implementation sets during construction.

Specified by:

getLevel in interface Logger

Returns:

the level.

setPostLevel

public void setPostLevel(Logger.LEVEL newLevel)

This will set the default level of StringPoster posted entries. The default starts as DATA. That means, all posted strings will be treated as DATA level.

Specified by:

setPostLevel in interface Logger

Parameters:

newLevel - the new default level.

Throws:

SystemException

init

public void init(Logger.TYPE loggerType)
          throws SystemException

Initialized the logger. This will be done by the constructing system, typically the System or Kernel, so most users should not call this directly.

Specified by:

init in interface Logger

Parameters:

loggerType - The type of logger this should be. This is more a request than a demand.

Throws:

SystemException

debuggingOn

public void debuggingOn()

Turn debugging on. Logs with debug level priority will be passed.

Specified by:

debuggingOn in interface Debuggable

debuggingOff

public void debuggingOff()

Turn debugging off. Logs with debug level priority will not be passed.

Specified by:

debuggingOff in interface Debuggable

debuggingState

Get the current debugging state.

Specified by:

debuggingState in interface Debuggable

Returns:

debugging state
