Classe Java.util.zip.DeflaterOutputStream a Java

Classe Java.util.zip.DeflaterInputStream a Java Aquesta classe implementa un filtre de flux de sortida per comprimir dades en el format de compressió "desinflat". També s'utilitza com a base per a altres tipus de filtres de compressió com GZIPOutputStream. Constructors i descripció
    DeflaterOutputStream (sortida OutputStream):Crea un flux de sortida nou amb un compressor i una mida de memòria intermèdia per defecte. DeflaterOutputStream(OutputStream out boolean syncFlush):Crea un nou flux de sortida amb un compressor predeterminat, una mida de memòria intermèdia predeterminada i el mode de neteja especificat. DeflaterOutputStream(OutputStream out Deflater def):Crea un nou flux de sortida amb el compressor especificat i una mida de memòria intermèdia predeterminada. DeflaterOutputStream(OutputStream out Deflater def boolean syncFlush):Crea un flux de sortida nou amb el mode de neteja del compressor especificat i una mida de memòria intermèdia predeterminada. DeflaterOutputStream(OutputStream out Deflater def int mida):Crea un flux de sortida nou amb el compressor i la mida del buffer especificats. DeflaterOutputStream(OutputStream out Deflater def int size boolean syncFlush):Crea un flux de sortida nou amb la mida del buffer del compressor i el mode de neteja especificats.
Mètodes:
    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
    desinflat de buit protegit(): Writes next block of compressed data to the output stream. 
      Syntax :  protected void deflate() throws IOException   Throws:   IOException
    acabat buit(): 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
