Class ClassAliasIdResolver

java.lang.Object

com.fasterxml.jackson.databind.jsontype.impl.TypeIdResolverBase

com.fasterxml.jackson.databind.jsontype.impl.ClassNameIdResolver

com.google.code.ssm.json.ClassAliasIdResolver

All Implemented Interfaces:

TypeIdResolver

public class ClassAliasIdResolver
extends ClassNameIdResolver

To minimalize size of serialized json object instead of full qualified class name each class can be registered under alias (id). This alias (id) will be used in serialized string to mark type of object (required in deserialization). Alias (id) must be unique! If alias is not defined for class then full qualified name is used.
