Constructor Detail

CompressedInputStream

public CompressedInputStream(InputStream in)

Creates a new compressed input stream.
The buffersize adapts dynamically to the packet size.

Parameters:

in - the underlying input stream

Method Detail

close

public void close()
           throws IOException

Description copied from class: java.io.FilterInputStream

Closes this input stream and releases any system resources associated with the stream. This method simply performs in.close().

Specified by:

close in interface Closeable

Overrides:

close in class FilterInputStream

Throws:

IOException - if an I/O error occurs.

See Also:

FilterInputStream.in

isClosed

public boolean isClosed()

Returns the closed state.

Returns:

true if closed

read

public int read()
         throws IOException

Reads the next uncompressed byte of data from the input stream.

Overrides:

read in class FilterInputStream

Returns:

the next byte of data, or -1 if the end of the stream is reached.

Throws:

IOException - if an I/O error occurs.

See Also:

FilterInputStream.in

read

public int read(byte[] b,
                int off,
                int len)
         throws IOException

Reads up to len uncompressed bytes of data from this input stream into an array of bytes.

Overrides:

read in class FilterInputStream

Parameters:

b - the buffer into which the data is read.

off - the start offset in the destination array b

len - the maximum number of bytes read.

Returns:

the total number of bytes read into the buffer, or -1 if there is no more data because the end of the stream has been reached.

Throws:

IOException - if an I/O error occurs.
