All Implemented Interfaces:
JsonFormatVisitable, SchemaAware, ContextualSerializer, ResolvableSerializer, Serializable
Direct Known Subclasses:
BeanAsArraySerializer, BeanSerializer, UnwrappingBeanSerializer
public abstract class BeanSerializerBase extends StdSerializer<Object> implements ContextualSerializer, ResolvableSerializer, JsonFormatVisitable, SchemaAware
Base class both for the standard bean serializer, and couple of variants that only differ in small details. Can be used for custom bean serializers as well, although that is not the primary design goal.

    • resolve

      public void resolve(SerializerProvider provider) throws JsonMappingException
      We need to implement ResolvableSerializer to be able to properly handle cyclic type references.
      Specified by:
      resolve in interface ResolvableSerializer
      Parameters:
      provider - Provider that has constructed serializer this method is called on.
      Throws:
      JsonMappingException

    • findConvertingSerializer

      protected JsonSerializer<Object> findConvertingSerializer(SerializerProvider provider, BeanPropertyWriter prop) throws JsonMappingException
      Helper method that can be used to see if specified property is annotated to indicate use of a converter for property value (in case of container types, it is container type itself, not key or content type).
      Throws:
      JsonMappingException
      Since:
      2.2

    • createContextual

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

    • properties

      public Iterator<PropertyWriter> properties()
      Description copied from class: JsonSerializer
      Accessor for iterating over logical properties that the type handled by this serializer has, from serialization perspective. Actual type of properties, if any, will be BeanPropertyWriter. Of standard Jackson serializers, only BeanSerializer exposes properties.
      Overrides:
      properties in class JsonSerializer<Object>

    • usesObjectId

      public boolean usesObjectId()
      Description copied from class: JsonSerializer
      Method that can be called to see whether this serializer instance will use Object Id to handle cyclic references.
      Overrides:
      usesObjectId in class JsonSerializer<Object>

    • serialize

      public abstract void serialize(Object bean, JsonGenerator gen, 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<Object>
      Parameters:
      bean - 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:
      IOException

    • serializeWithType

      public void serializeWithType(Object bean, JsonGenerator gen, 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.
      Overrides:
      serializeWithType in class JsonSerializer<Object>
      Parameters:
      bean - 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.
      typeSer - Type serializer to use for including type information
      Throws:
      IOException

      @Deprecated public JsonNode getSchema(SerializerProvider provider, Type typeHint) throws JsonMappingException
