Class TarGzOutputStream

  • All Implemented Interfaces:
    Closeable, Flushable, AutoCloseable

    public class TarGzOutputStream
    extends TarOutputStreamImpl
    Outputs tar.gz files. Added functionality that it doesn't need to know the size of an entry. If an entry has zero size when it is put in the Tar, then it buffers it until it's closed and it knows the size.

      • putNextEntry

        public void putNextEntry​(TarEntry entry)
                          throws IOException
        Description copied from class: TarOutputStreamImpl
        Put an entry on the output stream. This writes the entry's header record and positions the output stream for writing the contents of the entry. Once this method is called, the stream is ready for calls to write() to write the entry's contents. Once the contents are written, closeEntry() MUST be called to ensure that all buffered data is completely written to the output stream.
        Overrides:
        putNextEntry in class TarOutputStreamImpl
        Parameters:
        entry - The TarEntry to be written to the archive.
        Throws:
        IOException
      • closeEntry

        public void closeEntry()
                        throws IOException
        Description copied from class: TarOutputStreamImpl
        Close an entry. This method MUST be called for all file entries that contain data. The reason is that we must buffer data written to the stream in order to satisfy the buffer's record based writes. Thus, there may be data fragments still being assembled that must be written to the output stream before this entry is closed and the next entry written.
        Overrides:
        closeEntry in class TarOutputStreamImpl
        Throws:
        IOException
      • write

        public void write​(byte[] b)
                   throws IOException
        Description copied from class: TarOutputStreamImpl
        Writes bytes to the current tar archive entry. This method simply calls read( byte[], int, int ).
        Overrides:
        write in class TarOutputStreamImpl
        Parameters:
        b - The buffer to write to the archive.
        Throws:
        IOException
      • write

        public void write​(byte[] b,
                          int start,
                          int length)
                   throws IOException
        Description copied from class: TarOutputStreamImpl
        Writes bytes to the current tar archive entry. This method is aware of the current entry and will throw an exception if you attempt to write bytes past the length specified for the current entry. The method is also (painfully) aware of the record buffering required by TarBuffer, and manages buffers that are not a multiple of recordsize in length, including assembling records from small buffers. This method simply calls read( byte[], int, int ).
        Overrides:
        write in class TarOutputStreamImpl
        Parameters:
        b - The buffer to write to the archive.
        start - The offset in the buffer from which to get bytes.
        length - The number of bytes to write.
        Throws:
        IOException
