public java.io.InputStream getInputStream()

clearClassCache

public void clearClassCache()
                     throws java.io.IOException

Description copied from interface: Unmarshaller

Discard the class cache. Implicitly also discards the instance cache.

Throws:

java.io.IOException - if an error occurs

clearInstanceCache

public void clearInstanceCache()
                        throws java.io.IOException

Description copied from interface: Unmarshaller

Discard the instance cache.

Throws:

close

public void close()
           throws java.io.IOException

Throws:

java.io.IOException

finish

public void finish()
            throws java.io.IOException

Finish unmarshalling from a stream. Any transient class or instance cache is discarded.

Specified by:

finish in interface Unmarshaller

Overrides:

finish in class AbstractUnmarshaller

Throws:

java.io.IOException - if an error occurs

start

public void start(ByteInput byteInput)
           throws java.io.IOException

Begin unmarshalling from a stream.

Specified by:

start in interface Unmarshaller

Overrides:

Throws:

java.io.IOException - if an error occurs during setup, such as an invalid header

read

public int read()
         throws java.io.IOException

Reads the next byte of data from the input stream. If no byte is available because the end of the stream has been reached, the value -1 is returned. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.

Specified by:

read in class AbstractUnmarshaller

Returns:

the next byte, or -1 if the end of stream has been reached

java.io.IOException - if an error occurs

read

public int read(byte[] b)
         throws java.io.IOException

Read some bytes from the input stream into the given array. Returns the number of bytes actually read (possibly zero), or -1 if the end of stream has been reached.

Specified by:

read in interface java.io.ObjectInput

Specified by:

read in interface ByteInput

Overrides:

read in class AbstractUnmarshaller

Parameters:

Overrides:

read in class AbstractUnmarshaller

Parameters:

b - the destination array
