Constructor Detail

JULLogger

public JULLogger(java.util.logging.Logger logger)

Parameters:

logger - The java.util.logging.Logger to output to.

Method Detail

getLevel

public Level getLevel()

Specified by:

getLevel in interface Logger

Returns:

The Level that logging is set to.

isEnabled

public boolean isEnabled(Level level)

Description copied from interface: Logger

Check if a logging level is enabled.

Specified by:

isEnabled in interface Logger

Parameters:

level - The Level to check.

Returns:

true if logging is enabled for that level.

isErrorEnabled

public boolean isErrorEnabled()

Specified by:

isErrorEnabled in interface Logger

Returns:

true if the log level Level.ERROR is enabled.

errorWriter

public LogWriter errorWriter()

Specified by:

errorWriter in interface Logger

Returns:

A LogWriter that writes logs at level ERROR.

isWarnEnabled

public boolean isWarnEnabled()

Specified by:

isWarnEnabled in interface Logger

Returns:

true if the log level Level.WARN is enabled.

warnWriter

public LogWriter warnWriter()

Specified by:

warnWriter in interface Logger

Returns:

A LogWriter that writes logs at level WARN.

isInfoEnabled

public boolean isInfoEnabled()

Specified by:

isInfoEnabled in interface Logger

Returns:

true if the log level Level.INFO is enabled.

infoWriter

public LogWriter infoWriter()

Specified by:

infoWriter in interface Logger

Returns:

A LogWriter that writes logs at level INFO.

isDebugEnabled

public boolean isDebugEnabled()

Specified by:

isDebugEnabled in interface Logger

Returns:

true if the log level Level.DEBUG is enabled.

debugWriter

public LogWriter debugWriter()

Specified by:

debugWriter in interface Logger

Returns:

A LogWriter that writes logs at level DEBUG.

batch

public void batch(java.util.function.Consumer<Logger> fn)

Description copied from interface: Logger

Write a set of log messages in a batch.

The specified Consumer will be invoked with a Logger that collects all log output and then writes them all consecutively when the consumer invocation returns. Use this when a set of log lines must appear consecutively in the log, regardless of time ordering.

Note: most implementations do not guarantee log ordering, so log lines may not always be ordered correctly by timestamp. This is especially true when logs are written in batch.

Specified by:

batch in interface Logger

Parameters:

fn - A Consumer that will be invoked with the batching Logger.
