Constructor Details

AbstractUnmarshaller

protected AbstractUnmarshaller(AbstractMarshallerFactory marshallerFactory,
 MarshallingConfiguration configuration)

Construct a new unmarshaller instance.

Parameters:

marshallerFactory - the marshaller factory

configuration -

Method Details

start

public void start(ByteInput byteInput)
           throws IOException

Start reading from the given input. The internal buffer is discarded.

Specified by:

start in interface Unmarshaller

Overrides:

start in class SimpleDataInput

Parameters:

byteInput - the new input from which to read

Throws:

IOException - not thrown by this implementation, but may be overridden to be thrown if a problem occurs

finish

public void finish()
            throws IOException

Finish reading from the current input. The internal buffer is discarded, not flushed.

Specified by:

finish in interface Unmarshaller

Overrides:

finish in class SimpleDataInput

Throws:

IOException - not thrown by this implementation, but may be overridden to be thrown if a problem occurs

filterCheck

protected final void filterCheck(Class<?> unmarshallClass,
 long arrayLength,
 long depth,
 long references,
 long streamBytes)
                          throws InvalidClassException

Throws:

InvalidClassException

setObjectInputStreamFilter

protected static void setObjectInputStreamFilter(ObjectInputStream ois,
 UnmarshallingObjectInputFilter unmarshallingFilter)

Creates an ObjectInputFilter adapter to given UnmarshallingFilter, and sets the filter to given ObjectInputStream.

This essentially delegates the filtering functionality to underlying ObjectInputStream.

Parameters:

ois - ObjectInputStream instance to set the filter to.

unmarshallingFilter - UnmarshallingObjectInputFilter instance to delegate filtering decisions to.
