Constructor Detail

• ContainerSerializer

  protected ContainerSerializer(Class<T> t)

• ContainerSerializer

  protected ContainerSerializer(JavaType fullType)

  Since:

  2.5

• ContainerSerializer

  protected ContainerSerializer(Class<?> t,
                                boolean dummy)

  Alternate constructor that is (alas!) needed to work around kinks of generic type handling

  Parameters:

  t -

• ContainerSerializer

  protected ContainerSerializer(ContainerSerializer<?> src)

Method Detail

• withValueTypeSerializer

  public ContainerSerializer<?> withValueTypeSerializer(TypeSerializer vts)

  Factory(-like) method that can be used to construct a new container serializer that uses specified TypeSerializer for decorating contained values with additional type information.

  Parameters:

  vts - Type serializer to use for contained values; can be null, in which case 'this' serializer is returned as is

  Returns:

  Serializer instance that uses given type serializer for values if that is possible (or if not, just 'this' serializer)

• getContentType

  public abstract JavaType getContentType()

  Accessor for finding declared (static) element type for type this serializer is used for.

• getContentSerializer

  public abstract JsonSerializer<?> getContentSerializer()

  Accessor for serializer used for serializing contents (List and array elements, Map values etc) of the container for which this serializer is used, if it is known statically. Note that for dynamic types this may return null; if so, caller has to instead use getContentType() and SerializerProvider.findValueSerializer(java.lang.Class<?>, com.fasterxml.jackson.databind.BeanProperty).

• hasSingleElement

  public abstract boolean hasSingleElement(T value)

  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.

• _withValueTypeSerializer

  protected abstract ContainerSerializer<?> _withValueTypeSerializer(TypeSerializer vts)

  Method that needs to be implemented to allow construction of a new serializer object with given TypeSerializer, used when addition type information is to be embedded.

• hasContentTypeAnnotation

  @Deprecated
  protected boolean hasContentTypeAnnotation(SerializerProvider provider,
                                                         BeanProperty property)

  Deprecated. Since 2.7: should not be needed; should be enough to see if type has 'isStatic' modifier
  Helper method used to encapsulate logic for determining whether there is a property annotation that overrides element type; if so, we can and need to statically find the serializer.

  Since:

  2.1
