BaseMarshallerDelegate (ProtoStream - core 4.5.0.Dev04 API)

java.lang.Object
- org.infinispan.protostream.impl.BaseMarshallerDelegate<T>

Direct Known Subclasses:

EnumMarshallerDelegate
```
public abstract class BaseMarshallerDelegate<T>
extends Object
```
The marshallers (descendants of BaseMarshaller) do not have a uniform interface, so an extra layer of indirection is used to provide uniformity. A delegate object wraps the real marshaller and delegates actual marshalling to it, taking into account the specific interface differences for each kind of marshaller (EnumMarshaller, MessageMarshaller, ProtoStreamMarshaller).
