Modifier and Type	Method and Description
void	deserializeAndSet(JsonParser p, DeserializationContext ctxt, Object instance) Method called to deserialize appropriate value, given parser (and context), and set it using appropriate mechanism.
Object	deserializeSetAndReturn(JsonParser p, DeserializationContext ctxt, Object instance) Alternative to SettableBeanProperty.deserializeAndSet(com.fasterxml.jackson.core.JsonParser, com.fasterxml.jackson.databind.DeserializationContext, java.lang.Object) that returns either return value of setter method called (if one is), or null to indicate that no return value is available.

<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.
AnnotatedMember	getMember() Method for accessing primary physical entity that represents the property; annotated field, method or constructor property.
void	set(Object instance, Object value) Method called to assign given value to this property, on specified Object.
Object	setAndReturn(Object instance, Object value) Method called to assign given value to this property, on specified Object, and return whatever delegating accessor returned (if anything)

Field Detail

_annotated

protected final AnnotatedField _annotated

_field

protected final transient Field _field

Actual field to set when deserializing this property. Transient since there is no need to persist; only needed during construction of objects.

_skipNulls

protected final boolean _skipNulls

Since:

2.9

Method Detail

withName

public SettableBeanProperty withName(PropertyName newName)

Description copied from class: SettableBeanProperty

Fluent factory method for constructing and returning a new instance with specified property name. Note that this method should NOT change configuration of this instance.

Specified by:

withName in class SettableBeanProperty

Parameters:

newName - Name to use for the new instance.

Returns:

Newly constructed instance, if property name differs from the one used for this instance; or 'this' if not.

withValueDeserializer

public SettableBeanProperty withValueDeserializer(JsonDeserializer<?> deser)

Description copied from class: SettableBeanProperty

Fluent factory method for constructing and returning a new instance with specified value deserializer. Note that this method should NOT change configuration of this instance.

Specified by:

withValueDeserializer in class SettableBeanProperty

Parameters:

deser - Deserializer to assign to the new property instance

Returns:

Newly constructed instance, if value deserializer differs from the one used for this instance; or 'this' if not.

withNullProvider

public SettableBeanProperty withNullProvider(NullValueProvider nva)

Specified by:

withNullProvider in class SettableBeanProperty

fixAccess

public void fixAccess(DeserializationConfig config)

Description copied from class: SettableBeanProperty

Method called to ensure that the mutator has proper access rights to be called, as per configuration. Overridden by implementations that have mutators that require access, fields and setters.

Overrides:

fixAccess in class SettableBeanProperty

getAnnotation

public <A extends Annotation> A getAnnotation(Class<A> acls)

Description copied from interface: BeanProperty

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.

Specified by:

getAnnotation in interface BeanProperty

Specified by:

getAnnotation in class SettableBeanProperty

getMember

public AnnotatedMember getMember()

Description copied from interface: BeanProperty

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

Specified by:

getMember in interface BeanProperty

Specified by:

getMember in class SettableBeanProperty

deserializeAndSet

public void deserializeAndSet(JsonParser p,
                              DeserializationContext ctxt,
                              Object instance)
                       throws IOException

Description copied from class: SettableBeanProperty

Method called to deserialize appropriate value, given parser (and context), and set it using appropriate mechanism. Pre-condition is that passed parser must point to the first token that should be consumed to produce the value (the only value for scalars, multiple for Objects and Arrays).

Specified by:

deserializeAndSet in class SettableBeanProperty

Throws:

IOException

deserializeSetAndReturn

public Object deserializeSetAndReturn(JsonParser p,
                                      DeserializationContext ctxt,
                                      Object instance)
                               throws IOException

Description copied from class: SettableBeanProperty

Alternative to SettableBeanProperty.deserializeAndSet(com.fasterxml.jackson.core.JsonParser, com.fasterxml.jackson.databind.DeserializationContext, java.lang.Object) that returns either return value of setter method called (if one is), or null to indicate that no return value is available. Mostly used to support Builder style deserialization.

Specified by:

deserializeSetAndReturn in class SettableBeanProperty

Throws:

IOException

set

public void set(Object instance,
                Object value)
         throws IOException

Description copied from class: SettableBeanProperty

Method called to assign given value to this property, on specified Object.

Note: this is an optional operation, not supported by all implementations, creator-backed properties for example do not support this method.

Specified by:

set in class SettableBeanProperty

Throws:

IOException

setAndReturn

public Object setAndReturn(Object instance,
                           Object value)
                    throws IOException

Description copied from class: SettableBeanProperty

Method called to assign given value to this property, on specified Object, and return whatever delegating accessor returned (if anything)

Note: this is an optional operation, not supported by all implementations, creator-backed properties for example do not support this method.

Specified by:

setAndReturn in class SettableBeanProperty

Throws:

IOException
