Examples with ByteBuf org.bson.ByteBuf used on opensource projects

Example 1 with ByteBuf

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

the class ByteBufferBsonOutput method getByteBuffers.

@Override
public List<ByteBuf> getByteBuffers() {
    ensureOpen();
    List<ByteBuf> buffers = new ArrayList<ByteBuf>(bufferList.size());
    for (final ByteBuf cur : bufferList) {
        buffers.add(cur.duplicate().flip());
    }
    return buffers;
}

Example 2 with ByteBuf

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

the class ByteBufBsonDocument method create.

static List<ByteBufBsonDocument> create(final ResponseBuffers responseBuffers) {
    int numDocuments = responseBuffers.getReplyHeader().getNumberReturned();
    ByteBuf documentsBuffer = responseBuffers.getBodyByteBuffer();
    documentsBuffer.order(ByteOrder.LITTLE_ENDIAN);
    List<ByteBufBsonDocument> documents = new ArrayList<ByteBufBsonDocument>(numDocuments);
    while (documents.size() < numDocuments) {
        int documentSizeInBytes = documentsBuffer.getInt();
        documentsBuffer.position(documentsBuffer.position() - 4);
        ByteBuf documentBuffer = documentsBuffer.duplicate();
        documentBuffer.limit(documentBuffer.position() + documentSizeInBytes);
        documents.add(new ByteBufBsonDocument(documentBuffer));
        documentsBuffer.position(documentsBuffer.position() + documentSizeInBytes);
    }
    return documents;
}

Example 3 with ByteBuf

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

the class ByteBufBsonDocument method toJson.

@Override
public String toJson(final JsonWriterSettings settings) {
    StringWriter stringWriter = new StringWriter();
    JsonWriter jsonWriter = new JsonWriter(stringWriter, settings);
    ByteBuf duplicate = byteBuf.duplicate();
    BsonBinaryReader reader = new BsonBinaryReader(new ByteBufferBsonInput(duplicate));
    try {
        jsonWriter.pipe(reader);
        return stringWriter.toString();
    } finally {
        duplicate.release();
        reader.close();
    }
}

Example 4 with ByteBuf

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

the class ByteBufBsonDocument method create.

static List<ByteBufBsonDocument> create(final ByteBufferBsonOutput bsonOutput, final int startPosition) {
    CompositeByteBuf outputByteBuf = new CompositeByteBuf(bsonOutput.getByteBuffers());
    outputByteBuf.position(startPosition);
    List<ByteBufBsonDocument> documents = new ArrayList<ByteBufBsonDocument>();
    int curDocumentStartPosition = startPosition;
    while (outputByteBuf.hasRemaining()) {
        int documentSizeInBytes = outputByteBuf.getInt();
        ByteBuf slice = outputByteBuf.duplicate();
        slice.position(curDocumentStartPosition);
        slice.limit(curDocumentStartPosition + documentSizeInBytes);
        documents.add(new ByteBufBsonDocument(slice));
        curDocumentStartPosition += documentSizeInBytes;
        outputByteBuf.position(outputByteBuf.position() + documentSizeInBytes - 4);
    }
    return documents;
}

Example 5 with ByteBuf

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

the class ByteBufferBsonOutput method write.

protected void write(final int absolutePosition, final int value) {
    ensureOpen();
    if (absolutePosition < 0) {
        throw new IllegalArgumentException(String.format("position must be >= 0 but was %d", absolutePosition));
    }
    if (absolutePosition > position - 1) {
        throw new IllegalArgumentException(String.format("position must be <= %d but was %d", position - 1, absolutePosition));
    }
    BufferPositionPair bufferPositionPair = getBufferPositionPair(absolutePosition);
    ByteBuf byteBuffer = getByteBufferAtIndex(bufferPositionPair.bufferIndex);
    byteBuffer.put(bufferPositionPair.position++, (byte) value);
}
