Class LegacySerializationPolicy

java.lang.Object

com.google.gwt.user.server.rpc.SerializationPolicy

com.google.gwt.user.server.rpc.impl.LegacySerializationPolicy

All Implemented Interfaces:

TypeNameObfuscator

public class LegacySerializationPolicy
extends SerializationPolicy
implements TypeNameObfuscator

A serialization policy compatible with GWT 1.3.3 RPC. This is used when no serialization policy file is present.

The set of allowed types are:

1. Primitives
2. Types assignable to IsSerializable
3. Types with custom field serializers
4. Arrays of the above types

Types that derive from Serializable but do not meet any of the above criteria may not be serialized as leaf types. However, their fields may be serialized as super types of a legal type.

Parameters:

clazz - the class to be transmitted

Returns:

the obfuscated type identifier.

Throws:

SerializationException
