| final public static int | GZIP_MAGIC
GZIP header magic number. | | protected CRC32 | crc
CRC-32 for uncompressed data. | | protected boolean | eos

Closes this input stream and releases any system resources associated
with the stream. | | public int | read(byte[] buf, int off, int len)
Reads uncompressed data into an array of bytes. |
| GZIP_MAGIC | | final public static int GZIP_MAGIC(Code) | | GZIP header magic number.

| 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 |
| close | | public void close() throws IOException(Code) | | Closes this input stream and releases any system resources associated
with the 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. If len is not
zero, the method will block until some input can be decompressed; otherwise,
no bytes are read and 0 is returned.
Parameters:
buf - the buffer into which the data is read
Parameters:
off - the start offset in the destination array b
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:
NullPointerException - If buf is null.
exception:
IndexOutOfBoundsException - If off is negative, len is negative, or len is greater than buf.length - off
exception:
IOException - if an I/O error has occurred or the compressedinput data is corrupt |
