Class UnmarshallingContext

java.lang.Object

com.db4o.internal.AbstractBufferContext

com.db4o.internal.marshall.AbstractReadContext

com.db4o.internal.marshall.ObjectHeaderContext

com.db4o.internal.marshall.ObjectReferenceContext

com.db4o.internal.marshall.UnmarshallingContext

All Implemented Interfaces:

AspectVersionContext, HandlerVersionContext, InternalReadContext, MarshallingInfo, ObjectIdContext, BufferContext, Context, ReadBuffer, ReadContext, ReferenceActivationContext

public class UnmarshallingContext
extends ObjectReferenceContext
implements HandlerVersionContext, ReferenceActivationContext

Wraps the low-level details of reading a Buffer, which in turn is a glorified byte array.
