public interface BeanProperty extends Named
Bean properties are logical entities that represent data that Java objects (POJOs (Plain Old Java Objects), sometimes also called "beans") contain; and that are accessed using accessors (methods like getters and setters, fields, constructor parameters). Instances allow access to annotations directly associated to property (via field or method), as well as contextual annotations (annotations for class that contains properties).

Instances are not typically passed when constructing serializers and deserializers, but rather only passed when context is known when ContextualSerializer and ContextualDeserializer resolution occurs (createContextual(...) method is called). References may (need to) be retained by serializers and deserializers, especially when further resolving dependent handlers like value serializers/deserializers or structured types.

  • Method Details

    • getName

      String getName()
      Method to get logical name of the property
      Specified by:
      getName in interface Named
    • getFullName

      PropertyName getFullName()
      Method for getting full name definition, including possible format-specific additional properties (such as namespace when using XML backend).
      Since:
      2.3
    • getType

      JavaType getType()
      Method to get declared type of the property.
    • getWrapperName

      PropertyName getWrapperName()
      If property is indicated to be wrapped, name of wrapper element to use.
      Since:
      2.2
    • getMetadata

      PropertyMetadata getMetadata()
      Accessor for additional optional information about property.
      Returns:
      Metadata about property; never null.
      Since:
      2.3
    • isRequired

      boolean isRequired()
      Whether value for property is marked as required using annotations or associated schema. Equivalent to: getMetadata().isRequired()
      Since:
      2.2
    • isVirtual

      boolean isVirtual()
      Accessor for checking whether there is an actual physical property behind this property abstraction or not.
      Since:
      2.7
    • getAnnotation

      <A extends Annotation> A getAnnotation(Class<A> acls)
      Method for finding annotation associated with this property; meaning annotation associated with one of entities used to access property.

      Note that this method should only be called for custom annotations; access to standard Jackson annotations (or ones supported by alternate AnnotationIntrospectors) should be accessed through AnnotationIntrospector.

    • getContextAnnotation

      <A extends Annotation> A getContextAnnotation(Class<A> acls)
      Method for finding annotation associated with context of this property; usually class in which member is declared (or its subtype if processing subtype).

      Note that this method should only be called for custom annotations; access to standard Jackson annotations (or ones supported by alternate AnnotationIntrospectors) should be accessed through AnnotationIntrospector.

    • getMember

      AnnotatedMember getMember()
      Method for accessing primary physical entity that represents the property; annotated field, method or constructor property.
    • findFormatOverrides

      @Deprecated com.fasterxml.jackson.annotation.JsonFormat.Value findFormatOverrides(AnnotationIntrospector intr)
      Convenience method that is roughly equivalent to
         return intr.findFormat(getMember());
      
      and specifically does NOT try to find per-type format defaults to merge; use findPropertyFormat(com.fasterxml.jackson.databind.cfg.MapperConfig<?>, java.lang.Class<?>) if such defaults would be useful.
      Since:
      2.6
    • findPropertyFormat

      com.fasterxml.jackson.annotation.JsonFormat.Value findPropertyFormat(MapperConfig<?> config, Class<?> baseType)
      Helper method used to look up format settings applicable to this property, considering both possible per-type configuration settings
      Since:

    • findPropertyInclusion

      com.fasterxml.jackson.annotation.JsonInclude.Value findPropertyInclusion(MapperConfig<?> config, Class<?> baseType)
      Convenience method that is roughly equivalent to
         return config.getAnnotationIntrospector().findPropertyInclusion(getMember());
      
      but also considers global default settings for inclusion
      Since:
      2.7
    • findAliases

      List<PropertyName> findAliases(MapperConfig<?> config)
      Method for accessing set of possible alternate names that are accepted during deserialization.

      List (possibly empty) of alternate names; never null

    • depositSchemaProperty

      void depositSchemaProperty(JsonObjectFormatVisitor objectVisitor, SerializerProvider provider) throws JsonMappingException
      Method that can be called to visit the type structure that this property is part of. Note that not all implementations support traversal with this method; those that do not should throw UnsupportedOperationException.

      NOTE: Starting with 2.7, takes explicit SerializerProvider argument to reduce the need to rely on provider visitor may or may not have assigned.

      Parameters:
      objectVisitor - Visitor to used as the callback handler
      Throws:
      JsonMappingException
      Since:
