Method Detail

isLogEnabled

public boolean isLogEnabled(TracingLogger.Event event)

Description copied from class: TracingLogger

Test if a tracing support is enabled (according to propertiesDelegate setting) and if event can be logged (according to event.level and threshold level set).

Specified by:

isLogEnabled in class TracingLogger

Parameters:

event - event type to be tested

Returns:

true if event can be logged

log

public void log(TracingLogger.Event event,
                java.lang.Object... args)

Description copied from class: TracingLogger

Try to log event according to event level and request context threshold level setting.

Specified by:

log in class TracingLogger

Parameters:

event - event type to be logged

args - message arguments (in relation to .Event#messageFormat()

logDuration

public void logDuration(TracingLogger.Event event,
                        long fromTimestamp,
                        java.lang.Object... args)

Description copied from class: TracingLogger

Try to log event according to event level and request context threshold level setting. If logging support is switched on for current request and event setting the method computes duration of event and log message. If fromTimestamp is not set (i.e. -1) then duration of event is 0.

Specified by:

logDuration in class TracingLogger

Parameters:

event - event type to be logged

fromTimestamp - logged event is running from the timestamp in nanos. -1 in case event has no duration

args - message arguments (in relation to .Event#messageFormat()

timestamp

public long timestamp(TracingLogger.Event event)

Description copied from class: TracingLogger

If logging support is switched on for current request and event setting the method returns current timestamp in nanos.

Specified by:

timestamp in class TracingLogger

Parameters:

event - event type to be logged

Returns:

Current timestamp in nanos or -1 if tracing is not enabled

flush

public void flush(javax.ws.rs.core.MultivaluedMap<java.lang.String,java.lang.Object> headers)

Description copied from class: TracingLogger

Stores collected tracing messages to response HTTP header.

Specified by:

flush in class TracingLogger

Parameters:

headers - message headers.

logImpl

private void logImpl(TracingLogger.Event event,
                     long duration,
                     java.lang.Object... messageArgs)

Log message for specified event type. The event contains name, category, level and also message format. Message format will be formatted by parameter messageArgs is used to format event. If there is no message format then each message arg is separated by space. Final message also contains event name (JDK Log) or category (HTTP header) and time stamp.

Parameters:

event - Event type of log

duration - Time duration of logged event. Can be 0.

messageArgs - message arguments

isEnabled

private boolean isEnabled(TracingLogger.Level level)

Parameters:

instance - instance to be formatted

textSB - Formatted info will be appended to StringBuilder

formatResponse

private static void formatResponse(javax.ws.rs.core.Response response,
                                   java.lang.StringBuilder textSB)
