    --- | ---
    `protected void` | `_collectAndResolve(AnnotatedClass annotatedType, NamedType namedType, MapperConfig<?> config, AnnotationIntrospector ai, java.util.HashMap<NamedType,NamedType> collectedSubtypes)` Method called to find subtypes for a specific type (class), using type (class) as the unique key (in case of conflicts).
    `protected void` | `_collectAndResolveByTypeId(AnnotatedClass annotatedType, NamedType namedType, MapperConfig<?> config, java.util.Set<java.lang.Class<?>> typesHandled, java.util.Map<java.lang.String,NamedType> byName)` Method called to find subtypes for a specific type (class), using type id as the unique key (in case of conflicts).
    `protected java.util.Collection<NamedType>` | `_combineNamedAndUnnamed(java.util.Set<java.lang.Class<?>> typesHandled, java.util.Map<java.lang.String,NamedType> byName)` Helper method used for merging explicitly named types and handled classes without explicit names.
    `java.util.Collection<NamedType>` | `collectAndResolveSubtypesByClass(MapperConfig<?> config, AnnotatedClass type)` Method for finding out all reachable subtypes for given type, such that access is by type, typically needed for serialization (converting from type to type name).
    `java.util.Collection<NamedType>` | `collectAndResolveSubtypesByClass(MapperConfig<?> config, AnnotatedMember property, JavaType baseType)` Method for finding out all reachable subtypes for a property specified by given element (method or field), such that access is by type, typically needed for serialization (converting from type to type name).
    `java.util.Collection<NamedType>` | `collectAndResolveSubtypesByTypeId(MapperConfig<?> config, AnnotatedClass type)` Method for finding out all reachable subtypes for given type, such that access is by type id, typically needed for deserialization (converting from type id to type).
    `java.util.Collection<NamedType>` | `collectAndResolveSubtypesByTypeId(MapperConfig<?> config, AnnotatedMember property, JavaType baseType)` Method for finding out all reachable subtypes for a property specified by given element (method or field), such that access is by type id, typically needed for deserialization (converting from type id to type).
    `void` | `registerSubtypes(java.lang.Class<?>... classes)`
    `void` | `registerSubtypes(NamedType... types)` Method for registering specified subtypes (possibly including type names); for type entries without name, non-qualified class name as used as name (unless overridden by annotation).
