Java.util.zip.GZIPInputStream klase Java valodā

Šī klase ievieš straumes filtru saspiestu datu lasīšanai GZIP faila formātā. Konstruktori
    GZIPInputStream(InputStream in) :Izveido jaunu ievades straumi ar noklusējuma bufera lielumu. GZIPInputStream (InputStream int izmērā):Izveido jaunu ievades straumi ar norādīto bufera izmēru.
Metodes:
    tukša aizvēršana () : Closes this input stream and releases any system resources associated with the stream.
      Syntax :  public void close() throws IOException   Specified by:   close in interface Closeable   Specified by:   close in interface AutoCloseable   Overrides:   close in class InflaterInputStream   Throws:   IOException 
    int lasīt(baits[] buf int off int len) : Reads uncompressed data into an array of bytes. If len is not zero the method will block until some input can be decompressed; otherwise no bytes are read and 0 is returned.
      Syntax :  public int read(byte[] buf int off int len) throws IOException   Overrides:   read in class InflaterInputStream   Parameters:   buf - 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 stream is reached   Throws:   NullPointerException IndexOutOfBoundsException ZipException IOException
