Example 6 with BasicBSONEncoder

use of org.bson.BasicBSONEncoder in project bson4jackson by michel-kraemer.

the class BsonParserTest method parseUndefined.

/**
 * Test if undefined values are deserialized correct (i.e. if they
 * are skipped if the object is deserialized into a {@link Map})
 * @throws Exception if something goes wrong
 */
@Test
public void parseUndefined() throws Exception {
    BSONObject o = new BasicBSONObject();
    o.put("Undefined", new Object());
    o.put("Int32", 5);
    BSONEncoder enc = new BasicBSONEncoder() {

        @Override
        protected boolean putSpecial(String name, Object o) {
            putUndefined(name);
