Class AsArraySerializerBase<T>

    • Method Detail

      • createContextual

        public JsonSerializer<?> createContextual​(SerializerProvider serializers,
                                          BeanProperty property)
                                   throws JsonMappingException
        This method is needed to resolve contextual annotations like per-property overrides, as well as do recursive call to createContextual of content serializer, if known statically.
        Specified by:
        createContextual in interface ContextualSerializer
        Parameters:
        serializers - Serializer provider to use for accessing config, other serializers
        property - Method or field that represents the property (and is used to access value to serialize). Should be available; but there may be cases where caller cannot provide it and null is passed instead (in which case impls usually pass 'this' serializer as is)
        Returns:
        Serializer to use for serializing values of specified property; may be this instance or a new instance.
        Throws:
        JsonMappingException

      • serialize

        public void serialize​(T value,
                      JsonGenerator gen,
                      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<T>
        Parameters:
        value - Value to serialize; can not be null.
        gen - 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​(T 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.
        Overrides:
        serializeWithType in class JsonSerializer<T>
        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
