Java.util.zip.InflaterInputStream-klassen i Java

Denne klassen implementerer et strømfilter for å dekomprimere data i "deflate"-komprimeringsformatet. Den brukes også som grunnlag for andre dekompresjonsfiltre som GZIPInputStream. Konstruktører
    InflaterInputStream(InputStream inn):Oppretter en ny inngangsstrøm med standard dekomprimerings- og bufferstørrelse. InflaterInputStream(InputStream i Inflater inf):Oppretter en ny inngangsstrøm med den spesifiserte dekomprimeringen og en standard bufferstørrelse. InflaterInputStream(InputStream i Inflater inf int size):Oppretter en ny inngangsstrøm med den angitte dekomprimerings- og bufferstørrelsen.
Metoder:
    int tilgjengelig(): 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 
    void close() : Closes this input stream and releases any system resources associated with the stream.
      Syntax :   public void close() throws IOException   Throws:   IOException 
    beskyttet void fill(): 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.
    boolesk 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 read(): 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 
    void reset() : 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 
    langt hopp(lang 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
