  • Constructor Details

    • NativeConversion

      public NativeConversion(AdapterOutputType outputType, String filename, long userdata)
      Creates a new conversion object for the conversion of file data (e.g. provided in-memory or via a native socket).
      Parameters:
      outputType - The format to convert the file to
      filename - The (fully qualified) name of the file to convert
      userdata - Opaque user data (usually a pointer) provided via JNI.
  • Method Details

    • close

      public void close()
      Description copied from class: Conversion
      Used by the Connectivity Framework to close this Conversion object. This method is invoked by the Connectivity Framework. A File Filter adapter implementation should not use it.
      Overrides:
      close in class Conversion
    • isLocalFile

      public boolean isLocalFile()
      Returns true if the file to convert exists on the local file system.
      Specified by:
      isLocalFile in class Conversion
    • read

      public int read(byte[] data, int offset, int count) throws Exception
      Read file data.

      You must use either this method to access file data or the input stream. Do not use both; once you use the input stream this method will no longer return any data.

      Specified by:
      read in class Conversion
      Parameters:
      data - Byte array to receive data
      offset - Offset into the byte array at which data starts getting written
      count - The number of bytes to read
      Returns:
      The number of bytes actually read
      Throws:
      Exception
    • getInputStream

      public InputStream getInputStream() throws Exception
      Returns an input stream for the file data associated with this Conversion object.

      You must use either this method to access file data or the read method. Do not use both; once you use the input stream, the read method will no longer return any data.

      Specified by:
      getInputStream in class Conversion
      Returns:
      A new InputStream to the file data
      Throws:
      Exception - IOException if the input stream could not be created
