Example 1 with CoordinateSequence

use of com.vividsolutions.jts.geom.CoordinateSequence in project GeoGig by boundlessgeo.

the class PointCacheTest method testLargeSequences.

private void testLargeSequences(final int numNodes) {
    List<Long> nodeIds = new ArrayList<Long>(numNodes / 6);
    Stopwatch sw = Stopwatch.createStarted();
    for (int n = 0; n < numNodes; n++) {
        if (n % 20 == 0) {
            nodeIds.add(Long.valueOf(n));
        }
        cache.put((long) n, coord(n, n));
    }
    System.err.printf("%,d nodes added in %s\n", numNodes, sw.stop());
    Collections.shuffle(nodeIds);
    sw.reset().start();
    CoordinateSequence sequence = cache.get(nodeIds);
    System.err.printf("requested %,d coordinates in %s\n", nodeIds.size(), sw.stop());
    assertNotNull(sequence);
    assertEquals(nodeIds.size(), sequence.size());
    long approxDbSize = caclDbSize();
    System.err.printf("Approx db size: %,f MB\n\n", ((double) approxDbSize / 1024D / 1024D));
}
