public class GZIPInputStream
extends InflaterInputStream
This class implements a stream filter for reading compressed data in the GZIP format.

Variable Index

 o crc
CRC-32 for uncompressed data.
 o eos
Indicates end of input stream.
 o GZIP_MAGIC
GZIP header magic number.

Constructor Index

 o GZIPInputStream(InputStream)
Creates a new input stream with a default buffer size.
 o GZIPInputStream(InputStream, int)
Creates a new input stream with the specified buffer size.

Method Index

 o close()
Closes the input stream.
 o read(byte[], int, int)
Reads uncompressed data into an array of bytes.

Variables

 o crc
 protected CRC32 crc
CRC-32 for uncompressed data.

 o eos
 protected boolean eos
Indicates end of input stream.

 o GZIP_MAGIC
 public static final int GZIP_MAGIC
GZIP header magic number.

Constructors

 o GZIPInputStream
 public GZIPInputStream(InputStream in,
                        int size) throws IOException
Creates a new input stream with the specified buffer size.

Parameters:
in - the input stream
size - the input buffer size
Throws: IOException
if an I/O error has occurred
 o GZIPInputStream
 public GZIPInputStream(InputStream in) throws IOException
Creates a new input stream with a default buffer size.

Parameters:
in - the input stream
Throws: IOException
if an I/O error has occurred

Methods

 o read
 public int read(byte buf[],
                 int off,
                 int len) throws IOException
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
off - the start offset of the data
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: IOException
if an I/O error has occurred or the compressed input data is corrupt
Overrides:
read in class InflaterInputStream
 o close
 public void close() throws IOException
Closes the input stream.

Throws: IOException
if an I/O error has occurred
Overrides:
close in class FilterInputStream
