JAVA.UTIL.ZIP.DEFLATEROUTPUTSTREAM KLASE JAVA VALODĀ

Java.util.zip.DeflaterInputStream klase Java valodā Šī klase ievieš izvades straumes filtru datu saspiešanai “deflācijas” saspiešanas formātā. To izmanto arī par pamatu cita veida kompresijas filtriem, piemēram, GZIPOutputStream. Konstruktori un apraksts

DeflaterOutputStream(OutputStream out): Izveido jaunu izvades straumi ar noklusējuma kompresoru un bufera izmēru. DeflaterOutputStream (OutputStream out Būla syncFlush) : Izveido jaunu izvades straumi ar noklusējuma kompresoru, noklusējuma bufera izmēru un norādīto skalošanas režīmu. DeflaterOutputStream (OutputStream out Deflater def) : Izveido jaunu izvades straumi ar norādīto kompresoru un noklusējuma bufera izmēru. DeflaterOutputStream(OutputStream out Deflater def Boolean syncFlush) : Izveido jaunu izvades straumi ar norādīto kompresora skalošanas režīmu un noklusējuma bufera izmēru. DeflaterOutputStream(OutputStream out Deflater def int size) : Izveido jaunu izvades straumi ar norādīto kompresora un bufera izmēru. DeflaterOutputStream(OutputStream out Deflater def int size Būla syncFlush) : Izveido jaunu izvades straumi ar norādīto kompresora bufera izmēru un skalošanas režīmu. Metodes:

  Syntax :  public void close() throws IOException   Overrides:   close in class FilterOutputStream   Throws:   IOException

  Syntax :  protected void deflate() throws IOException   Throws:   IOException

  Syntax :  public void finish() throws IOException   Throws:   IOException

  Syntax :  public void flush() throws IOException   Overrides:   flush in class FilterOutputStream   Throws:   IOException

  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

  Syntax :  public void write(int b) throws IOException   Overrides:   write in class FilterOutputStream   Parameters:   b - the byte to be written   Throws:   IOException
