Interface Looper

All Known Implementing Classes:

AbstractLooper

public interface Looper

A looper is one that makes loops. A loop is a processing unit that is executed repetitively. Processing duration is not restricted. Anyway, loop() implementation should consider that thread checks for interruption state between loops - for this reason blocking IO read operations are not allowed.

This interface is designed to work with LooperThread, see sample code below.

 class DemoLooper implements Looper {
        private LooperThread thread;
 
        DemoLooper() {
                tread = new LooperThread(this);
                thread.start();
        }
 
        void stop() {
                thread.stop();
        }
 
        void loop() throws Exception {
                ...
        }
 }

void	loop() Execute a single processing loop.

Method Detail

loop

void loop()
   throws Exception

Execute a single processing loop. Implementation has no formal restriction on processing duration but should consider thread interruption state is checked between loops.

Throws:

Exception - every exception on loop processing is bubbled up.
