Class SettableBeanProperty

java.lang.Object

org.codehaus.jackson.map.deser.SettableBeanProperty

All Implemented Interfaces:

BeanProperty, Named

Direct Known Subclasses:

CreatorProperty, SettableBeanProperty.FieldProperty, SettableBeanProperty.InnerClassProperty, SettableBeanProperty.ManagedReferenceProperty, SettableBeanProperty.MethodProperty, SettableBeanProperty.SetterlessProperty

public abstract class SettableBeanProperty
extends Object
implements BeanProperty

Base class for settable properties of a bean: contains both type and name definitions, and reflection-based set functionality. Concrete sub-classes implement details, so that both field- and setter-backed properties can be handled

Nested Class Summary

Nested Classes

Modifier and Type	Class and Description
static class	SettableBeanProperty.FieldProperty This concrete sub-class implements property that is set directly assigning to a Field.
static class	SettableBeanProperty.InnerClassProperty This sub-class is used to handle special case of value being a non-static inner class.
static class	SettableBeanProperty.ManagedReferenceProperty Wrapper property that is used to handle managed (forward) properties (see [JACKSON-235] for more information).
static class	SettableBeanProperty.MethodProperty This concrete sub-class implements property that is set using regular "setter" method.
protected static class	SettableBeanProperty.NullProvider To support [JACKSON-420] we need bit more indirection; this is used to produce artificial failure for primitives that don't accept JSON null as value.
static class	SettableBeanProperty.SetterlessProperty This concrete sub-class implements Collection or Map property that is indirectly by getting the property value and directly modifying it.

Field Summary

Fields

Modifier and Type	Field and Description
protected Annotations	_contextAnnotations Class that contains this property (either class that declares the property or one of its subclasses), class that is deserialized using deserializer that contains this property.
protected String	_managedReferenceName If property represents a managed (forward) reference (see [JACKSON-235]), we will need name of reference for later linking.
protected SettableBeanProperty.NullProvider	_nullProvider Object used to figure out value to be used when 'null' literal is encountered in JSON.
protected int	_propertyIndex Index of property (within all property of a bean); assigned when all properties have been collected.
protected String	_propName Logical name of the property (often but not always derived from the setter method name)
protected JavaType	_type Base type for property; may be a supertype of actual value.
protected JsonDeserializer<Object>	_valueDeserializer Deserializer used for handling property value.
protected TypeDeserializer	_valueTypeDeserializer If value will contain type information (to support polymorphic handling), this is the type deserializer used to handle type resolution.

Field Detail

_propName

protected final String _propName

Logical name of the property (often but not always derived from the setter method name)

_type

protected final JavaType _type

Base type for property; may be a supertype of actual value.

_contextAnnotations

protected final Annotations _contextAnnotations

Class that contains this property (either class that declares the property or one of its subclasses), class that is deserialized using deserializer that contains this property.

_valueDeserializer

protected JsonDeserializer<Object> _valueDeserializer

Deserializer used for handling property value.

_valueTypeDeserializer

protected TypeDeserializer _valueTypeDeserializer

If value will contain type information (to support polymorphic handling), this is the type deserializer used to handle type resolution.

_nullProvider

protected SettableBeanProperty.NullProvider _nullProvider

Object used to figure out value to be used when 'null' literal is encountered in JSON. For most types simply Java null, but for primitive types must be a non-null value (like Integer.valueOf(0) for int).

Since:

1.7

_managedReferenceName

protected String _managedReferenceName

If property represents a managed (forward) reference (see [JACKSON-235]), we will need name of reference for later linking.

_propertyIndex

protected int _propertyIndex

Index of property (within all property of a bean); assigned when all properties have been collected. Order of entries is arbitrary, but once indexes are assigned they are not changed.

Since:

1.7
