Package uk.ac.starlink.ttools.cone
Class ConeMatcher.ConeWorker
java.lang.Object
uk.ac.starlink.ttools.cone.ConeMatcher.ConeWorker
- All Implemented Interfaces:
Runnable
,TableProducer
- Enclosing class:
ConeMatcher
Object which produces the result table.
It performs the individual cone searches and writes the results
down a pipe from which it will be read asynchronously for output.
To use an instance of this class, it is necessary to
call its run
method in a separate thread.
The getTable
method may be called before
the run
method has completed (or even started),
and will return a table whose rows may be streamed.
The run method checks for interruptions, so interrupting the thread in which it runs will cause it to stop consuming resources.
This code was originally written for J2SE1.4.
There may be less baroque ways of achieving the same effect using
the J2SE5 java.util.concurrent classes (BlockingQueue
).
