Method Detail

log

public void log(Severity severity,
                Object... data)

Description copied from interface: Logger

Logs message with a provide Severity. Useful for dynamically determined Severity messages.

Specified by:

log in interface Logger

Specified by:

log in class AbstractLogger

getLogMetaProvider

public LogMetaProvider getLogMetaProvider()

getArgumentFormatterContainer

public ArgumentFormatterContainer getArgumentFormatterContainer()

getListenerContainer

public ListenerContainer getListenerContainer()

getSignatureFormatterContainer

public SignatureFormatterContainer getSignatureFormatterContainer()

broadcast

protected void broadcast(Severity severity,
                         Object... data)

This will broadcast the log message to all the Listener instances registered with this object. The epoch for the log messages will be set to the start of this method, and will be used for all calls to Listener.log().

format

protected String format(Object... data)

This will use the installed "SignatureFormatter" and "ArgumentFormatter" objects to format the provided arguments into a log-able string. This will call the static "format" method with the required data.

format

protected String format(List<Object> arguments)

This will use the provided SignatureFormatters and ArgumentFormatters objects to format the provided arguments into a log-able string. This will return null if there are no arguments provided. This will not catch any Exceptions encountered. If any of the formatters thrown an exception, this will fall back on a default formatting that is minimal but still useful.
