| GZIPInputStream | | public GZIPInputStream(InputStream in, int size) throws IOException(Code) | | Creates a new input stream with the specified buffer size.
Parameters:
in - the input stream
Parameters:
size - the input buffer size
exception:
IOException - if an I/O error has occurred
exception:
IllegalArgumentException - if size is <= 0 |
| GZIPInputStream | | public GZIPInputStream(InputStream in) throws IOException(Code) | | Creates a new input stream with a default buffer size.
Parameters:
in - the input stream
exception:
IOException - if an I/O error has occurred |
| read | | public int read(byte[] buf, int off, int len) throws IOException(Code) | | Reads uncompressed data into an array of bytes. Blocks until enough
input is available for decompression.
Parameters:
buf - the buffer into which the data is read
Parameters:
off - the start offset of the data
Parameters:
len - the maximum number of bytes read the actual number of bytes read, or -1 if the end of thecompressed input stream is reached
exception:
IOException - if an I/O error has occurred or the compressedinput data is corrupt |
