org.eclipse.paho.client.mqttv3.logging.package.html Maven / Gradle / Ivy
Provides facilities to write and format log and trace to help debug problems.
The default log and trace facility uses Java's build in log facility:-
java.util.logging. For systems where this is not available or where
an alternative logging framework is required the logging facility can be
replaced using {@link org.eclipse.paho.client.mqttv3.logging.LoggerFactory#setLogger(String)}
which takes an implementation of the {@link org.eclipse.paho.client.mqttv3.logging.Logger}
interface.
A sample java.util.logging properties file - jsr47min.properties is provided that demonstrates
how to run with a memory based trace facility that runs with minimal performance
overhead. The memory buffer can be dumped when a log/trace record is written matching
the MemoryHandlers trigger level or when the push method is invoked on the MemoryHandler.
{@link org.eclipse.paho.client.mqttv3.util.Debug Debug} provides method to make it easy
to dump the memory buffer as well as other useful debug info.
