Java.util.zip.DeflaterOutputStream-klass i Java

Java.util.zip.DeflaterInputStream klass i Java Den här klassen implementerar ett utströmsfilter för att komprimera data i komprimeringsformatet "deflate". Den används också som grund för andra typer av komprimeringsfilter som GZIPOutputStream. Konstruktörer och beskrivning
    DeflaterOutputStream(OutputStream ut):Skapar en ny utström med en standardkompressor och buffertstorlek. DeflaterOutputStream(OutputStream out boolean syncFlush) :Skapar en ny utström med en standardkompressor, en standardbuffertstorlek och det specificerade spolläget. DeflaterOutputStream(OutputStream out Deflater def) :Skapar en ny utström med den angivna kompressorn och en standardbuffertstorlek. DeflaterOutputStream(OutputStream out Deflater def boolean syncFlush) :Skapar en ny utström med angivet kompressorspolningsläge och en standardbuffertstorlek. DeflaterOutputStream(OutputStream out Deflater def int size):Skapar en ny utström med angiven kompressor och buffertstorlek. DeflaterOutputStream(OutputStream out Deflater def int size boolean syncFlush):Skapar en ny utström med angiven kompressorbuffertstorlek och spolningsläge.
Metoder:
    void close() : Writes remaining compressed data to the output stream and closes the underlying stream.
      Syntax :  public void close() throws IOException   Overrides:   close in class FilterOutputStream   Throws:   IOException
    protected void deflate(): Writes next block of compressed data to the output stream.
      Syntax :  protected void deflate() throws IOException   Throws:   IOException
    void finish() : Finishes writing compressed data to the output stream without closing the underlying stream.
      Syntax :  public void finish() throws IOException   Throws:   IOException
    void flush() : Flushes the compressed output stream.
      Syntax :  public void flush() throws IOException   Overrides:   flush in class FilterOutputStream   Throws:   IOException
    void write(byte[] b int off int len) : Writes an array of bytes to the compressed output stream.
      Syntax :  public void write(byte[] b int off int len) throws IOException   Overrides:   write in class FilterOutputStream   Parameters:   b - the data to be written off - the start offset of the data len - the length of the data   Throws:   IOException
    void write(int b): Writes a byte to the compressed output stream.
      Syntax :  public void write(int b) throws IOException   Overrides:   write in class FilterOutputStream   Parameters:   b - the byte to be written   Throws:   IOException
