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 parametrers). 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 dependant handlers like value serializers/deserializers or structured types.

Nested Class Summary

Nested Classes

Modifier and Type	Interface and Description
static class	BeanProperty.Std Simple stand-alone implementation, useful as a placeholder or base class for more complex implementations.

Method Summary

Methods

Modifier and Type	Method and Description
void	depositSchemaProperty(JsonObjectFormatVisitor objectVisitor) Method that can be called to visit the type structure that this property is part of.
<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.
<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).
PropertyName	getFullName() Method for getting full name definition, including possible format-specific additional properties (such as namespace when using XML backend).
AnnotatedMember	getMember() Method for accessing primary physical entity that represents the property; annotated field, method or constructor property.
PropertyMetadata	getMetadata() Accessor for additional optional information about property.
String	getName() Method to get logical name of the property
JavaType	getType() Method to get declared type of the property.
PropertyName	getWrapperName() If property is indicated to be wrapped, name of wrapper element to use.
boolean	isRequired() Whether value for property is marked as required using annotations or associated schema.

Method Detail

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

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.

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).

getMember

AnnotatedMember getMember()

Method for accessing primary physical entity that represents the property; annotated field, method or constructor property.

depositSchemaProperty

void depositSchemaProperty(JsonObjectFormatVisitor objectVisitor)
                           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.

Parameters:

objectVisitor - Visitor to used as the callback handler

Throws:

JsonMappingException

Since:

2.2
