public class TransducerLog

extends ALog

Provides logging via ITransducer instances.

There are two ways to log using an this ILog instance. The first is to use the log(INode aNode) method. This requires that the INode instance contains INode instances that have the correct ID and data types. The second way is to use the log(ILogDatum aDatum) method. This is the preferred way to log data. Create a ILogDatum instance using the LogFactory.createLogDatum() method, then pass that ILogDatum instance to this ILog instance.

To create an instance of this ILog, see LogFactory.getLog().

Examples:

    TransducerLog log = new TransducerLog();
    log.setTransducer(new DefaultTransducer());
    ILogDatum datum = LogFactory.createLogDatum(new Date(),             // when
                                                "Machine Named George", // where
                                                5,                      // importance
                                                "A bad thing happened", // simple what
                                                myNode,                 // complex what
                                                "My App");              // who
    log.log( datum );
