Modified: java/src/org/apache/axis/encoding Serializer.java
Added: java/src/org/apache/axis/encoding
DeserializationContext.java DeserializerBase.java
SerializationContext.java ServiceDescription.java
TypeMapper.java
Removed: java/src/org/apache/axis/encoding Deserializer.java
TypeMappingRegistry.java
Log:
1st cut at new encoding system. Needs work!
This includes the (raw) beginnings of a service description framework,
which will hopefully be an abstract framework for understanding the
types of various parts of a message. An implementation of this
framework would handle WSDL.
