Field Detail

_config

protected final MapperConfig<?> _config

_typeToId

protected final ConcurrentHashMap<String,String> _typeToId

Mappings from class name to type id, used for serialization.

Since lazily constructed will require synchronization (either internal by type, or external)

_idToType

protected final Map<String,JavaType> _idToType

Mappings from type id to JavaType, used for deserialization.

Eagerly constructed, not modified, can use regular unsynchronized Map.

_caseInsensitive

protected final boolean _caseInsensitive

Since:

2.11

Constructor Detail

TypeNameIdResolver

protected TypeNameIdResolver(MapperConfig<?> config,
                             JavaType baseType,
                             ConcurrentHashMap<String,String> typeToId,
                             HashMap<String,JavaType> idToType)

Method Detail

construct

public static TypeNameIdResolver construct(MapperConfig<?> config,
                                           JavaType baseType,
                                           Collection<NamedType> subtypes,
                                           boolean forSer,
                                           boolean forDeser)

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.

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.

idFromClass

protected String idFromClass(Class<?> clazz)

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.

typeFromId

public JavaType typeFromId(DatabindContext context,
                           String id)

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

_typeFromId

protected JavaType _typeFromId(String id)

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

toString

public String toString()

Overrides:

toString in class Object

_defaultTypeId

protected static String _defaultTypeId(Class<?> cls)

If no name was explicitly given for a class, we will just use non-qualified class name
