Example 1 with PbfWriter

use of de.topobyte.osm4j.pbf.seq.PbfWriter in project osm4j-pbf by topobyte.

the class CopyElementwise method main.

public static void main(String[] args) throws IOException, OsmInputException {
    if (args.length != 2) {
        System.out.println("usage: " + CopyElementwise.class.getSimpleName() + " <input> <output>");
        System.exit(1);
    }
    InputStream input = new FileInputStream(args[0]);
    OutputStream output = new FileOutputStream(args[1]);
    final PbfWriter writer = new PbfWriter(output, true);
    PbfParser parser = new PbfParser(new OsmHandler() {

        @Override
        public void handle(OsmBounds bounds) throws IOException {
            writer.write(bounds);
        }

        @Override
        public void handle(OsmNode node) throws IOException {
            writer.write(node);
        }

        @Override
        public void handle(OsmWay way) throws IOException {
            writer.write(way);
        }

        @Override
        public void handle(OsmRelation relation) throws IOException {
            writer.write(relation);
        }

        @Override
        public void complete() throws IOException {
            writer.complete();

Example 2 with PbfWriter

use of de.topobyte.osm4j.pbf.seq.PbfWriter in project osm4j-pbf by topobyte.

the class Util method copyAndRead.

public static void copyAndRead(String resource, boolean readMetadata, boolean writeMetadata) throws IOException {
    InputStream input = Thread.currentThread().getContextClassLoader().getResourceAsStream(resource);
    OsmIterator iterator = new PbfIterator(input, readMetadata);
    File file = File.createTempFile("osm4j-test", "pbf");
    OutputStream output = new FileOutputStream(file);
    OsmOutputStream osmOutput = new PbfWriter(output, writeMetadata);
    for (EntityContainer container : iterator) {
        switch(container.getType()) {
            default:
            case Node:

                break;
        }
    }
