Class TemporaryData


  • @Deprecated
    public class TemporaryData
    extends Object
    Deprecated.
    this class is deprecated and will be removed from the next release, please use the OverflowBlob from axiom instead
    Class representing some temporary data in the form of a byte stream.

    Data is stored by writing to the output stream obtained using getOutputStream(). It can then be read back using the input stream obtained from getInputStream(). The data is first stored into a fixed size buffer. Once this buffer overflows, it is transferred to a temporary file. The buffer is divided into a given number of fixed size chunks that are allocated on demand. Since a temporary file may be created it is mandatory to call release() to discard the temporary data.

        public TemporaryData​(int numberOfChunks,
                             int chunkSize,
                             String tempPrefix,

    • Method Detail

      • getOutputStream

        public OutputStream getOutputStream()
        Deprecated.
      • readFrom

        public void readFrom​(InputStream in)
                      throws IOException
        Deprecated.
        Fill this object with data read from a given InputStream.

        A call tmp.readFrom(in) has the same effect as the following code:

         OutputStream out = tmp.getOutputStream();
         IOUtils.copy(in, out);
         out.close();
         
        However it does so in a more efficient way.
        Parameters:
        in - An InputStream to read data from. This method will not close the stream.
        Throws:
        IOException - in case of an error in reading from InputStream
      • writeTo

        public void writeTo​(OutputStream out)
                     throws IOException
        Deprecated.
        Write the data to a given output stream.
        Parameters:
        out - The output stream to write the data to. This method will not close the stream.
        Throws:
        IOException - in case of an error in writing to the OutputStream
      • getLength

        public long getLength()
        Deprecated.
      • release

        public void release()
        Deprecated.
