Class DateTimeSerializerBase<T>

    • Field Detail

      • _useTimestamp

        protected final Boolean _useTimestamp
        Flag that indicates that serialization must be done as the Java timestamp, regardless of other settings.
      • _customFormat

        protected final DateFormat _customFormat
        Specific format to use, if not default format: non null value also indicates that serialization is to be done as JSON String, not numeric timestamp, unless _useTimestamp is true.
      • _reusedCustomFormat

        protected final AtomicReference<DateFormat> _reusedCustomFormat
        If _customFormat is used, we will try to reuse instances in simplest possible form; thread-safe, but without overhead of ThreadLocal (not from code, but wrt retaining of possibly large number of format instances over all threads, properties with custom formats).
        Since:

        protected DateTimeSerializerBase(Class<T> type,

    • Method Detail

      • createContextual

        public JsonSerializer<?> createContextual(SerializerProvider serializers,
                                                  BeanProperty property)
                                           throws JsonMappingException
        Description copied from interface: ContextualSerializer
        Method called to see if a different (or differently configured) serializer is needed to serialize values of specified property. Note that instance that this method is called on is typically shared one and as a result method should NOT modify this instance but rather construct and return a new instance. This instance should only be returned as-is, in case it is already suitable for use.
        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
      • isEmpty

        public boolean isEmpty(SerializerProvider serializers,
                               T 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<T>
      • _timestamp

        protected abstract long _timestamp(T value)
      • serialize

        public abstract void serialize(T value,
                                       com.fasterxml.jackson.core.JsonGenerator gen,
                                       SerializerProvider serializers)
                                throws 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
        serializers - Provider that can be used to get serializers for serializing Objects value contains, if any.
        Throws:
        IOException
