Thread: copy patch question: byte format and efficiency
Hi, I am trying to stream selected columns of a file into the database. I am reading the file in with a BufferedReader wrapped FileReader. In a class implementing the InputStream interface I am filtering out the columns I like (to my luck only ints and floats) and write them into a ByteBuffer. The problem I discovered is that the format of the ByteBuffer is very different from the format that is used and works e.g. in the unit tests used in the copy patch. There the data is encoded into a ByteArrayOutputStream via a PrintStream and the ResultingByteArray is used in the constructor of an InputStream. Questions: Am I on the right track in general or is there a more efficient way? I was also thinking about subclassing FilterInputStream, but then I would have to construct the ints and floats myself. How can I encode the ints and floats into the byteArray (or a different buffer) in an efficient way in the correct format? thanks georg

This works now very well and its very simple. georg
