| int available() : | 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
| захищений 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.
| логічне значення 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
| довгий пропуск (довгий 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
