      • FSPURLConnection

        FSPURLConnection(URL u)

        creates a new URL connection with FSP protocol.

        Parameters:
        u - FSP URL of target

    • Method Detail

      • connect

         void connect()

        gets file status from FSP server throws IOException if there is problem with server communication

        Since:

        1.0

      • getConnectTimeout

         int getConnectTimeout()

        Get connection timeout.

        Returns:

        FSP session timeout (ms)

        Since:

        1.0rc8

      • getContentEncoding

         String getContentEncoding()

        FSP do not have concept of transfer encodings. All files are transfered in 8bit binary. This encoding is usually called "identity". Because this encoding should not be used in Content-Encoding http/1.1 reply header we return null here.

        Returns:

        null

        Since:

        1.0rc8

      • getContentLength

         int getContentLength()

        Get content-length. FSP v2 protocol support files up to 4 GB long. This function is not 64-bit LFS safe, it will return negative number for files 2-4GB long.

        Returns:

        file size in bytes

        Since:

        1.0rc8

      • getContentType

         String getContentType()

        Get content type. FSP v2 protocol does not supports content-type.

        Returns:

        null - content type not known

        Since:

        1.0rc8

      • getDate
