Class IndexedStringListSerializer

  • All Implemented Interfaces:
    JsonFormatVisitable, SchemaAware, ContextualSerializer, java.io.Serializable
    public final class IndexedStringListSerializer
extends StaticListSerializerBase<java.util.List<java.lang.String>>
    Efficient implement for serializing Lists that contains Strings and are random-accessible. The only complexity is due to possibility that serializer for String may be overridde; because of this, logic is needed to ensure that the default serializer is in use to use fastest mode, or if not, to defer to custom String serializer.

      • serialize

        public void serialize​(java.util.List<java.lang.String> value,
                      JsonGenerator g,
                      SerializerProvider provider)
               throws java.io.IOException
        Description copied from class: JsonSerializer
        Method that can be called to ask implementation to serialize values of type this serializer handles.
        Specified by:
        serialize in class StdSerializer<java.util.List<java.lang.String>>
        Parameters:
        value - Value to serialize; can not be null.
        g - Generator used to output resulting Json content
        provider - Provider that can be used to get serializers for serializing Objects value contains, if any.
        Throws:
        java.io.IOException

      • serializeWithType

        public void serializeWithType​(java.util.List<java.lang.String> value,
                              JsonGenerator g,
                              SerializerProvider provider,
                              TypeSerializer typeSer)
                       throws java.io.IOException
        Description copied from class: JsonSerializer
        Method that can be called to ask implementation to serialize values of type this serializer handles, using specified type serializer for embedding necessary type information.

        Default implementation will throw UnsupportedOperationException to indicate that proper type handling needs to be implemented.

        For simple datatypes written as a single scalar value (JSON String, Number, Boolean), implementation would look like: 

          // note: method to call depends on whether this type is serialized as JSON scalar, object or Array!
  typeSer.writeTypePrefixForScalar(value, gen);
  serialize(value, gen, provider);
  typeSer.writeTypeSuffixForScalar(value, gen);
        and implementations for type serialized as JSON Arrays or Objects would differ slightly, as START-ARRAY/END-ARRAY and START-OBJECT/END-OBJECT pairs need to be properly handled with respect to serializing of contents.
        Specified by:
        serializeWithType in class StaticListSerializerBase<java.util.List<java.lang.String>>
        Parameters:
        value - Value to serialize; can not be null.
        g - Generator used to output resulting Json content
        provider - Provider that can be used to get serializers for serializing Objects value contains, if any.
        typeSer - Type serializer to use for including type information
        Throws:
        java.io.IOException
