Class TarGzOutputStream

java.lang.Object
java.io.OutputStream
java.io.FilterOutputStream
org.jboss.shrinkwrap.impl.base.io.tar.TarOutputStreamImpl
org.jboss.shrinkwrap.impl.base.io.tar.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.

    • setDebug

      public void setDebug(boolean b)
      Description copied from class: TarOutputStreamImpl
      Sets the debugging flag.
      Overrides:
      setDebug in class TarOutputStreamImpl
      Parameters:
      b - True to turn on debugging.

    • setBufferDebug

      public void setBufferDebug(boolean b)
      Description copied from class: TarOutputStreamImpl
      Sets the debugging flag in this stream's TarBuffer.
      Overrides:
      setBufferDebug in class TarOutputStreamImpl

    • finish

      public void finish() throws IOException
      Description copied from class: TarOutputStreamImpl
      Ends the TAR archive without closing the underlying OutputStream. The result is that the EOF record of nulls is written.
      Overrides:
      finish in class TarOutputStreamImpl
      Throws:
      IOException

    • close

      public void close() throws IOException
      Description copied from class: TarOutputStreamImpl
      Ends the TAR archive and closes the underlying OutputStream. This means that finish() is called followed by calling the TarBuffer's close().
      Specified by:
      close in interface AutoCloseable
      Specified by:
      close in interface Closeable
      Overrides:
      close in class TarOutputStreamImpl
      Throws:
      IOException

    • getRecordSize

      public int getRecordSize()
      Description copied from class: TarOutputStreamImpl
      Get the record size being used by this stream's TarBuffer.
      Overrides:
      getRecordSize in class TarOutputStreamImpl
      Returns:
      The TarBuffer record 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(int b) throws IOException
      Description copied from class: TarOutputStreamImpl
      Writes a byte to the current tar archive entry. This method simply calls read( byte[], int, int ).
      Overrides:
      write in class TarOutputStreamImpl
      Parameters:
      b - The byte written.
      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

    • flush

      public void flush() throws IOException
      Specified by:
      flush in interface Flushable
      Overrides:
      flush in class FilterOutputStream
      Throws:
      IOException
