Examples with State com.baremaps.osm.domain.State used on opensource projects

Example 1 with State

use of com.baremaps.osm.domain.State in project baremaps by baremaps.

the class OpenStreetMapTest method monacoStateTxt.

@Test
void monacoStateTxt() throws URISyntaxException, IOException {
    try (InputStream inputStream = MONACO_STATE_TXT.openStream()) {
        State state = new OsmStateParser().state(inputStream);
        assertEquals(2788, state.getSequenceNumber());
        assertEquals(LocalDateTime.parse("2020-11-10T21:42:03"), state.getTimestamp());
    }
}

Example 2 with State

use of com.baremaps.osm.domain.State in project baremaps by baremaps.

the class UpdateService method call.

@Override
public Void call() throws Exception {
    Header header = headerRepository.selectLatest();
    String replicationUrl = header.getReplicationUrl();
    Long sequenceNumber = header.getReplicationSequenceNumber() + 1;
    Consumer<Entity> createGeometry = new CreateGeometryConsumer(coordinates, references);
    Consumer<Entity> reprojectGeometry = new ReprojectEntityConsumer(4326, srid);
    Consumer<Change> prepareGeometries = new ChangeEntityConsumer(createGeometry.andThen(reprojectGeometry));
    Function<Change, Change> prepareChange = consumeThenReturn(prepareGeometries);
    Consumer<Change> saveChange = new SaveChangeConsumer(nodeRepository, wayRepository, relationRepository);
    URI changeUri = resolve(replicationUrl, sequenceNumber, "osc.gz");
    Blob changeBlob = blobStore.get(changeUri);
    ProgressLogger progressLogger = new ProgressLogger(changeBlob.getContentLength(), 5000);
    try (InputStream blobInputStream = changeBlob.getInputStream();
        InputStream progressInputStream = new InputStreamProgress(blobInputStream, progressLogger);
        InputStream gzipInputStream = new GZIPInputStream(progressInputStream)) {
        new OsmChangeParser().changes(gzipInputStream).map(prepareChange).forEach(saveChange);
    }
    URI stateUri = resolve(replicationUrl, sequenceNumber, "state.txt");
    Blob stateBlob = blobStore.get(stateUri);
    try (InputStream stateInputStream = stateBlob.getInputStream()) {
        State state = new OsmStateParser().state(stateInputStream);
        headerRepository.put(new Header(state.getSequenceNumber(), state.getTimestamp(), header.getReplicationUrl(), header.getSource(), header.getWritingProgram()));
    }
    return null;
}

Example 3 with State

use of com.baremaps.osm.domain.State in project baremaps by baremaps.

the class OsmStateParser method state.

        String[] array = line.split("=");
        if (array.length == 2) {
            map.put(array[0], array[1]);
        }
    }
