Examples with OutputBuffer org.bson.io.OutputBuffer used on opensource projects

Example 6 with OutputBuffer

use of org.bson.io.OutputBuffer in project mongo-java-driver by mongodb.

the class MessageHelper method encodeJson.

private static ByteBuf encodeJson(final String json) {
    OutputBuffer outputBuffer = new BasicOutputBuffer();
    JsonReader jsonReader = new JsonReader(json);
    BsonDocumentCodec codec = new BsonDocumentCodec();
    BsonDocument document = codec.decode(jsonReader, DecoderContext.builder().build());
    BsonBinaryWriter writer = new BsonBinaryWriter(outputBuffer);
    codec.encode(writer, document, EncoderContext.builder().build());
    ByteBuffer documentByteBuffer = ByteBuffer.allocate(outputBuffer.size());
    documentByteBuffer.put(outputBuffer.toByteArray());
    return new ByteBufNIO(documentByteBuffer);
}

Example 7 with OutputBuffer

use of org.bson.io.OutputBuffer in project mongo-java-driver by mongodb.

the class BasicDBObject method toBson.

/**
 * Convert the object to its BSON representation, using the {@code STANDARD} representation for UUID.  This is safe to do in the context
 * of this class because currently this method is only used for equality and hash code, and is not passed to any other parts of the
 * library.

private static byte[] toBson(final BasicDBObject dbObject) {
    OutputBuffer outputBuffer = new BasicOutputBuffer();
    DEFAULT_CODEC.encode(new BsonBinaryWriter(outputBuffer), dbObject, EncoderContext.builder().build());
    return outputBuffer.toByteArray();
}
