public class CBZip2InputStream extends java.io.InputStream implements BZip2Constants
The decompression requires large amounts of memory. Thus you
should call the close()
method as soon as
possible, to force CBZip2InputStream to release the
allocated memory. See CBZip2OutputStream
for information about memory usage.
CBZip2InputStream reads bytes from the compressed
source stream via the single byte read()
method exclusively. Thus you should consider to use a
buffered source stream.
Instances of this class are not threadsafe.

Constructor and Description |
---|
CBZip2InputStream(java.io.InputStream in)
Constructs a new CBZip2InputStream which decompresses bytes read from
the specified stream.
|
public CBZip2InputStream(java.io.InputStream in) throws java.io.IOException
Although BZip2 headers are marked with the magic "Bz" this constructor expects the next byte in the stream to be the first one after the magic. Thus callers have to skip the first two bytes. Otherwise this constructor will throw an exception.
java.io.IOException
- if the stream content is malformed or an I/O error occurs.java.lang.NullPointerException
