Classe Java.util.zip.InflaterInputStream in Java

Questa classe implementa un filtro del flusso per decomprimere i dati nel formato di compressione "deflate". Viene anche utilizzato come base per altri filtri di decompressione come GZIPInputStream. Costruttori
    GonfiatoreInputStream(InputStream in):Crea un nuovo flusso di input con un decompressore e una dimensione del buffer predefiniti. InflaterInputStream(InputStream in Gonfiatore inf):Crea un nuovo flusso di input con il decompressore specificato e una dimensione del buffer predefinita. InflaterInputStream(InputStream nella dimensione inf int di Inflater):Crea un nuovo flusso di input con il decompressore e la dimensione del buffer specificati.
Metodi:
    int disponibile() : Returns 0 after EOF has been reached otherwise always return 1.
      Syntax :   public int available() throws IOException   Returns:   1 before EOF and 0 after EOF.   Throws:   IOException 
    vuoto vicino() : Closes this input stream and releases any system resources associated with the stream.
      Syntax :   public void close() throws IOException   Throws:   IOException 
    riempimento vuoto protetto() : Fills input buffer with more data to decompress.
      Syntax :   protected void fill() throws IOException   Throws:   IOException 
    void mark(int readlimit): Marks the current position in this input stream.
      Syntax :   public void mark(int readlimit)   Parameters:   readlimit - the maximum limit of bytes that can be read before the mark position becomes invalid.
    booleano markSupported() : Tests if this input stream supports the mark and reset methods.
      Syntax :   public boolean markSupported() Returns: a boolean indicating if this stream type supports the mark and reset methods. 
    int leggi() : Reads a byte of uncompressed data.
      Syntax :   public int read() throws IOException   Returns:   the byte read or -1 if end of compressed input is reached   Throws:   IOException
    int read(byte[] b int off int len) : Reads uncompressed data into an array of bytes.
      Syntax :   public int read(byte[] b int off int len) throws IOException   Parameters:   b - the buffer into which the data is read off - the start offset in the destination array b len - the maximum number of bytes read   Returns:   the actual number of bytes read or -1 if the end of the compressed input is reached.   Throws:   NullPointerException IndexOutOfBoundsException ZipException IOException 
    ripristino nullo() : Repositions this stream to the position at the time the mark method was last called on this input stream.
      Syntax :   public void reset() throws IOException   Throws:   IOException 
    salto lungo(lungo n): Skips specified number of bytes of uncompressed data.
      Syntax :   public long skip(long n) throws IOException   Parameters:   n - the number of bytes to skip   Returns:   the actual number of bytes skipped.   Throws:   IOException IllegalArgumentException
