Class AsWrapperTypeSerializer

java.lang.Object

com.fasterxml.jackson.databind.jsontype.TypeSerializer

com.fasterxml.jackson.databind.jsontype.impl.TypeSerializerBase

com.fasterxml.jackson.databind.jsontype.impl.AsWrapperTypeSerializer

public class AsWrapperTypeSerializer
extends TypeSerializerBase

Type wrapper that tries to use an extra JSON Object, with a single entry that has type name as key, to serialize type information. If this is not possible (value is serialize as array or primitive), will use JsonTypeInfo.As.WRAPPER_ARRAY mechanism as fallback: that is, just use a wrapping array with type information as the first element and value as second.
