 MapperConfig<?> config,
 PolymorphicTypeValidator ptv)

getMechanism

public JsonTypeInfo.Id getMechanism()

Description copied from interface: TypeIdResolver

Accessor for mechanism that this resolver uses for determining type id from type. Mostly informational; not required to be called or used.

Specified by:

getMechanism in interface TypeIdResolver

registerSubtype

public void registerSubtype(Class<?> type,
 String name)

idFromValue

public String idFromValue(Object value)

Description copied from interface: TypeIdResolver

Method called to serialize type of the type of given value as a String to include in serialized JSON content.

Specified by:

idFromValue in interface TypeIdResolver

idFromValueAndType

public String idFromValueAndType(Object value,
 Class<?> type)

Description copied from interface: TypeIdResolver

Alternative method used for determining type from combination of value and type, using suggested type (that serializer provides) and possibly value of that type. Most common implementation will use suggested type as is.

Specified by:

idFromValueAndType in interface TypeIdResolver

typeFromId

public JavaType typeFromId(DatabindContext context,
 String id)
                    throws IOException

Description copied from interface: TypeIdResolver

Method called to resolve type from given type identifier.

Specified by:

typeFromId in interface TypeIdResolver

Overrides:

typeFromId in class TypeIdResolverBase

Throws:

IOException

getDescForKnownTypeIds

public String getDescForKnownTypeIds()

Description copied from class: TypeIdResolverBase

Helper method used to get a simple description of all known type ids, for use in error messages.

Specified by:

getDescForKnownTypeIds in interface TypeIdResolver

Overrides:

getDescForKnownTypeIds in class TypeIdResolverBase
