Class EnumSetSerializer

    • Method Detail

      • isEmpty

        public boolean isEmpty​(SerializerProvider prov,
                               java.util.EnumSet<? extends java.lang.Enum<?>> value)
        Description copied from class: JsonSerializer
        Method called to check whether given serializable value is considered "empty" value (for purposes of suppressing serialization of empty values).

        Default implementation will consider only null values to be empty.

        NOTE: replaces JsonSerializer.isEmpty(Object), which was deprecated in 2.5

        Overrides:
        isEmpty in class JsonSerializer<java.util.EnumSet<? extends java.lang.Enum<?>>>
      • hasSingleElement

        public boolean hasSingleElement​(java.util.EnumSet<? extends java.lang.Enum<?>> value)
        Description copied from class: ContainerSerializer
        Method called to determine if the given value (of type handled by this serializer) contains exactly one element.

        Note: although it might seem sensible to instead define something like "getElementCount()" method, this would not work well for containers that do not keep track of size (like linked lists may not).

        Note, too, that as of now (2.9) this method is only called by serializer itself; and specifically is not used for non-array/collection types like Map or Map.Entry instances.

        Specified by:
        hasSingleElement in class ContainerSerializer<java.util.EnumSet<? extends java.lang.Enum<?>>>
      • serialize

        public final void serialize​(java.util.EnumSet<? extends java.lang.Enum<?>> 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.
        Overrides:
        serialize in class AsArraySerializerBase<java.util.EnumSet<? extends java.lang.Enum<?>>>
        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
      • serializeContents

        public void serializeContents​(java.util.EnumSet<? extends java.lang.Enum<?>> value,
                                      JsonGenerator gen,
                                      SerializerProvider provider)
                               throws java.io.IOException
        Throws:
        java.io.IOException
