GZIPInputStream | public class GZIPInputStream extends InflaterInputStream (Code) | | This class implements a stream filter for reading compressed data in
the GZIP file format.

Field Summary | |
final public static int | GZIP_MAGIC GZIP header magic number. | protected CRC32 | crc CRC-32 for uncompressed data. | protected boolean | eos Indicates end of input stream. |
Method Summary | |
public void | close() 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.
|
crc | protected CRC32 crc(Code) | | CRC-32 for uncompressed data.
|
eos | protected boolean eos(Code) | | Indicates end of input stream.

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 |
