Class TemporaryData

java.lang.Object
org.apache.synapse.commons.util.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.

    • TemporaryData

      public TemporaryData(int numberOfChunks, int chunkSize, String tempPrefix, String tempSuffix)
      Deprecated.

  • Method Details

    • 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

    • getInputStream

      public InputStream getInputStream() throws IOException
      Deprecated.
      Throws:
      IOException

    • 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.
