public class CompressionActivator extends Object
A utility class for layering compression streams on top of underlying byte streams based upon a specified compression algorithm.

  • Constructor Details

    • CompressionActivator

      public CompressionActivator(CompressionMethod compressionMethod)
      Creates a new instance.
      Parameters:
      compressionMethod - The compression method to employ.

  • Method Details

    • createCompressionOutputStream

      public OutputStream createCompressionOutputStream(OutputStream destinationStream)
      Wraps a compression stream around the destination stream based upon the requested compression method. If this method returns successfully, the input destination stream does not require closing after use because it will be closed when the returned output stream is closed.
      Parameters:
      destinationStream - The destination stream for receiving compressed data.
      Returns:
      A stream for writing compressed data to the destination stream.

    • createCompressionInputStream

      public InputStream createCompressionInputStream(InputStream sourceStream)
      Wraps a compression stream around the source stream based upon the requested compression method. If this method returns successfully, the input source stream does not require closing after use because it will be closed when the returned input stream is closed.
      Parameters:
      sourceStream - The source stream for providing compressed data.
      Returns:
      A stream for writing compressed data to the destination stream.
