Too slow to convert to java from cpp #213

Open aitazhixin opened 2 years ago

aitazhixin commented 2 years ago

There is a topic with type std_msgs/msg/Float32MultiArray. When the msg was received in APP, convert from cpp to java will spend 100ms. Because of array elements being convert to Float Object in java from c++ float. Why not generate Float32MultiArray with data type float[]?

@esteve can you help to convert List to float[]?
