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
