Class TimeoutQueueTupleIterTest

java.lang.Object
  junit.framework.Assert
      junit.framework.TestCase
          org.eigenbase.runtime.TimeoutQueueTupleIterTest

All Implemented Interfaces:

Test

public class TimeoutQueueTupleIterTest
extends TestCase

Test case for TimeoutQueueTupleIter.

Nested Class Summary

private static class

TimeoutQueueTupleIterTest.TickIterator Iterator which returns an element from an array on a regular basis.

Field Summary

private long	startTime Timestamp at which the test started.
private static int	tickMillis Multiplier which determines how long each logical clock tick lasts, and therefore how fast the test is run.

Constructor Summary

TimeoutQueueTupleIterTest(String s)

Method Summary

void	_testTimeoutTupleIter()
private void	assertFetchNext(TimeoutQueueTupleIter timeoutIter, Object expected, long timeoutMillis)
private void	assertFetchNextTimesOut(TimeoutQueueTupleIter timeoutIter, long timeoutMillis)
void	testDummy()
private long	toMillis(double tick)

Field Detail

tickMillis

private static final int tickMillis

Multiplier which determines how long each logical clock tick lasts, and therefore how fast the test is run. If you are getting sporadic problems, raise the value. 100 seems to be too low; 200 seems to be OK on my 1.8GHz laptop.

Constant Field Values

startTime

private long startTime

Timestamp at which the test started. All timeouts are relative to this.
