Example 8 with BsonBinaryReader

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

the class DBEncoderAdapter method encode.

// TODO: this can be optimized to reduce copying of buffers.  For that we'd need an InputBuffer that could iterate
//       over an array of ByteBuffer instances from a PooledByteBufferOutputBuffer
@Override
public void encode(final BsonWriter writer, final DBObject document, final EncoderContext encoderContext) {
    BasicOutputBuffer buffer = new BasicOutputBuffer();
    try {

        } finally {
            reader.close();
        }
    } finally {
        buffer.close();
    }
