      public static final LocalTimeSerializer INSTANCE

    • _useTimestamp

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

    • _useNanoseconds

      protected final Boolean _useNanoseconds
      Flag that indicates that numeric timestamp values must be written using nanosecond timestamps if the datatype supports such resolution, regardless of other settings.

    • _formatter

      protected final DateTimeFormatter _formatter
      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.

    • _shape

      protected final JsonFormat.Shape _shape

    • _integerListType

      protected transient volatile JavaType _integerListType
      Lazily constructed JavaType representing type List<Integer>.

    • serialize

      public void serialize(LocalTime value, JsonGenerator g, SerializerProvider provider) 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<LocalTime>
      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:
      IOException

    • serializeWithType

      public void serializeWithType(LocalTime value, JsonGenerator g, SerializerProvider provider, TypeSerializer typeSer) throws 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.
      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:
      IOException

    • serializationShape

      protected JsonToken serializationShape(SerializerProvider provider)
      Overridable helper method used from JsonSerializer.serializeWithType(T, com.fasterxml.jackson.core.JsonGenerator, com.fasterxml.jackson.databind.SerializerProvider, com.fasterxml.jackson.databind.jsontype.TypeSerializer), to indicate shape of value during serialization; needed to know how type id is to be serialized.

    • withFeatures

      protected com.fasterxml.jackson.datatype.jsr310.ser.JSR310FormattedSerializerBase<?> withFeatures(Boolean writeZoneId, Boolean writeNanoseconds)

    • acceptJsonFormatVisitor

      public void acceptJsonFormatVisitor(JsonFormatVisitorWrapper visitor, JavaType typeHint) throws JsonMappingException
      Description copied from class: StdSerializer
      Default implementation specifies no format. This behavior is usually overriden by custom serializers.
      Specified by:
      acceptJsonFormatVisitor in interface JsonFormatVisitable
      typeHint - Type of element (entity like property) being visited
      Throws:
      JsonMappingException

    • withFeatures

      @Deprecated protected com.fasterxml.jackson.datatype.jsr310.ser.JSR310FormattedSerializerBase<?> withFeatures(Boolean writeZoneId)
      Deprecated.
      Since:
      2.8

    • createContextual

      public JsonSerializer<?> createContextual(SerializerProvider prov, 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:
      prov - 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

    • getSchema

      @Deprecated public JsonNode getSchema(SerializerProvider provider, Type typeHint)
      Deprecated.
      Since 2.15
      Description copied from class: StdSerializer
      Default implementation simply claims type is "string"; usually overriden by custom serializers.
      Specified by:
      getSchema in interface SchemaAware
      Overrides:
      getSchema in class StdSerializer<T>
      Parameters:
      provider - The serializer provider.
      typeHint - A hint about the type.
      Returns:
      Json-schema for this serializer.

    • _acceptTimestampVisitor

      protected void _acceptTimestampVisitor(JsonFormatVisitorWrapper visitor, JavaType typeHint) throws JsonMappingException
      Throws:
      JsonMappingException

    • _integerListType

      protected JavaType _integerListType(SerializerProvider prov)

    • getTimestampsFeature

      protected SerializationFeature getTimestampsFeature()
      Overridable method that determines SerializationFeature that is used as the global default in determining if date/time value serialized should use numeric format ("timestamp") or not.

      Note that this feature is just the baseline setting and may be overridden on per-type or per-property basis.
