Class SimpleNameIdResolver

  • All Implemented Interfaces:
    TypeIdResolver, java.io.Serializable
    public class SimpleNameIdResolver
extends TypeIdResolverBase
implements java.io.Serializable
    TypeIdResolver implementation that converts using explicitly (annotation-) specified type names and maps to implementation classes; or, in absence of annotated type name, defaults to simple Class names (obtained with Class.getSimpleName(). Basically same as TypeNameIdResolver except for default to "simple" and not "full" class name.
    Since:
    2.16

      java.lang.String getDescForKnownTypeIds()
      Helper method used to get a simple description of all known type ids, for use in error messages.
      com.fasterxml.jackson.annotation.JsonTypeInfo.Id getMechanism()
      Accessor for mechanism that this resolver uses for determining type id from type.
      protected java.lang.String idFromClass​(java.lang.Class<?> clazz)  
      java.lang.String idFromValue​(java.lang.Object value)
      Method called to serialize type of the type of given value as a String to include in serialized JSON content.
      java.lang.String idFromValueAndType​(java.lang.Object value, java.lang.Class<?> type)
      Alternative method used for determining type from combination of value and type, using suggested type (that serializer provides) and possibly value of that type.
      java.lang.String toString()  
      JavaType typeFromId​(DatabindContext context, java.lang.String id)
      Method called to resolve type from given type identifier.

      • _typeToId

        protected final java.util.concurrent.ConcurrentHashMap<java.lang.String,​java.lang.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 java.util.Map<java.lang.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

      • getMechanism

        public com.fasterxml.jackson.annotation.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

      • idFromValue

        public java.lang.String idFromValue​(java.lang.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

                                           java.lang.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.
