Examples of com.google.appengine.api.log.LogQuery

com.google.appengine.api.log.LogQuery
opers.google.com/appengine/docs/java/runtime#The_Environment}"> the Java Servlet Environment documentation for how to retrieve these IDs at runtime. Malformed request IDs will cause an exception, while unrecognized request IDs be ignored. This option may not be combined with any filtering options such as startTime, endTime, offset, or minLogLevel. majorVersionIds and moduleVersions is ignored. IDs that do not correspond to a request log will be ignored. Logs will be returned in the order requested.
{@code batchSize} specifies the internal batching strategy of the returned{@link java.lang.Iterable Iterable<RequestLogs>}. Has no impact on the result of the query.
Notes on usage:
The recommended way to instantiate a {@code LogQuery} object is tostatically import {@link Builder}.* and invoke a static creation method followed by an instance mutator (if needed):
```
 import static com.google.appengine.api.log.LogQuery.Builder.*; ... // All requests, including application logs. iter = logService.fetch(withIncludeAppLogs(true)); // All requests ending in the past day (or still running) with an info log or higher. Calendar cal = Calendar.getInstance(); cal.add(Calendar.DAY_OF_MONTH, -1); iter = logService.fetch(withEndTimeMillis(cal.time()) .includeIncomplete(true).minimumLogLevel(LogService.INFO)); 
```

    super.tearDown();
  }


  private static void runTest(
      long timeOffset, long startTimeUsec, long endTimeUsec, int numShards, long[] startTimes) {
    LogQuery logQuery = LogQuery.Builder.withDefaults();
    logQuery.startTimeUsec(timeOffset + startTimeUsec);
    logQuery.endTimeUsec(timeOffset + endTimeUsec);
    LogInput input = new LogInput(logQuery, numShards);
    List<? extends InputReader<RequestLogs>> readers = input.createReaders();
    assertEquals("Incorrect number of readers", startTimes.length, readers.size());
    for (int i = 0; i < startTimes.length; i++) {
      LogInputReader reader = (LogInputReader) readers.get(i);
