org.das2.util.LoggerManager

Central place that keeps track of loggers. Note that both org.das.datum and org.das2.datum have this same class, which is there to avoid coupling between the packages.

LoggerManager( )

addHandlerToAll

addHandlerToAll( java.util.logging.Handler handler ) → void

Add the handler to all loggers created by this manager, and all future. Only call this once! I would think that adding a handler to the root would essentially add the handler to all loggers, but it doesn't seem to.

Parameters

handler - e.g. GraphicalLogHandler

Returns:

void (returns nothing)

clearTimer

clearTimer( ) → void

explicitly remove this timer.

Returns:

void (returns nothing)

getLogger

getLogger( String id ) → java.util.logging.Logger

return the requested logger, but add it to the list of known loggers.

Parameters

id - the name

Returns:

the Logger

getLoggers

getLoggers( ) → java.util.Set

return the list of known loggers.

Returns:

the list of known loggers.

isEnableTimers

isEnableTimers( ) → boolean

return enableTimers property.

Returns:

enableTimers property.

isUseTimeTaggingLoggers

isUseTimeTaggingLoggers( ) → boolean

are we keeping track of log message times, so we can sort loggers by how recently messages were posted?

Returns:

true if we are keeping track of log message times.

logExitGuiEvent

logExitGuiEvent( java.awt.event.ActionEvent e ) → void

call this at the end of the GUI event to measure time to respond.

Parameters

e - the focus event.

Returns:

void (returns nothing)

logExitGuiEvent( javax.swing.event.ChangeEvent e ) → void
logExitGuiEvent( java.awt.event.ItemEvent e ) → void
logExitGuiEvent( java.awt.event.FocusEvent e ) → void

logGuiEvent

logGuiEvent( java.awt.event.ActionEvent e ) → void

provide easy way to log all GUI events.

Parameters

e - an ActionEvent

Returns:

void (returns nothing)

logGuiEvent( javax.swing.event.ChangeEvent e ) → void
logGuiEvent( java.awt.event.ItemEvent e ) → void
logGuiEvent( java.awt.event.FocusEvent e ) → void

logPropertyChangeEvent

logPropertyChangeEvent( java.beans.PropertyChangeEvent e ) → void

log property change events. (I realized I spend a lot of time debugging walking through the property change fire event code, and I should just add a log message to all propertyChange codes.)

Parameters

e - a PropertyChangeEvent

Returns:

void (returns nothing)

logPropertyChangeEvent( java.beans.PropertyChangeEvent e, String source ) → void

markTime

markTime( ) → void

mark the time using the thread name.

Returns:

void (returns nothing)

[search for examples] [view on GitHub] [view on old javadoc] [view source]

markTime( String message ) → void

readConfiguration

readConfiguration( ) → void

A slightly more transparent logging configuration would provide feedback about what configuration file it's loading. This will echo when the configuration file would be. The idea is when you are completely frustrated with not getting the logger to behave, you can add: org.das2.util.LoggerManager.readConfiguration() to your code.

Returns:

void (returns nothing)

readConfiguration( String configfile ) → void

resetTimer

resetTimer( ) → void

reset the timer. The lifecycle is like so:

Note the timers are stored with weak references to the threads, so clearTimer needn't be called.

Returns:

void (returns nothing)

resetTimer( String task ) → void

setEnableTimers

setEnableTimers( boolean enableTimers ) → void

if enableTimers is true, then resetTimer and markTime have an effect. Each thread can have a timer to measure the execution time for a process.

Parameters

enableTimers - true to enable timers

Returns:

void (returns nothing)

setTimerLogfile

setTimerLogfile( String f ) → void

channel the logging information to here, setEnableTimers(false) to close.

Parameters

f - a String

Returns:

void (returns nothing)

setUseTimeTaggingLoggers

setUseTimeTaggingLoggers( boolean t ) → void

Parameters

t - a boolean

Returns:

void (returns nothing)
