}

Example 3 with BSONEncoder

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

the class BsonParserTest method parseAsText.

/**
 * Checks if the parser returns a textual representation of arbitrary
 * tokens. See issue #23.
 * @throws Exception if something went wrong
 */
@Test
public void parseAsText() throws Exception {
    BSONObject o = new BasicBSONObject();
    o.put("Float", 5.0f);
    o.put("Int32", 1234);
    BSONEncoder enc = new BasicBSONEncoder();
    byte[] b = enc.encode(o);
    ByteArrayInputStream bais = new ByteArrayInputStream(b);

Example 4 with BSONEncoder

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

the class BsonDeserializersTest method generateAndParse.

private static <T> T generateAndParse(Object o, Class<T> cls) throws Exception {
    BSONObject bo = new BasicBSONObject();
    // that's why all properties of classes in TC must be named 'obj'
    bo.put("obj", o);
    BSONEncoder encoder = new BasicBSONEncoder();
    byte[] barr = encoder.encode(bo);
    ByteArrayInputStream bais = new ByteArrayInputStream(barr);

    om.registerModule(new BsonModule());
    T r = om.readValue(bais, cls);
    return r;
}
