public class BeanPropertyWriter extends PropertyWriter implements Serializable
Note that current design tries to keep instances immutable (semi-functional style); mostly because these instances are exposed to application code and this is to reduce likelihood of data corruption and synchronization issues.

Modifier and Type | Field and Description |
---|---|
protected Method |
_accessorMethod
Accessor method used to get property value, for method-accessible
properties.
|
protected JavaType |
_cfgSerializationType
Type to use for locating serializer; normally same as return type of the
accessor method, but may be overridden by annotations.
|
protected Annotations |
_contextAnnotations
Annotations from context (most often, class that declares property, or in
case of sub-class serializer, from that sub-class)
|
protected JavaType |
_declaredType
Type property is declared to have, either in class definition or
associated annotations.
|
protected PropertySerializerMap |

|
protected Field |
_field

available for the Bean.
|
protected HashMap<Object,Object> |
_internalSettings |
protected AnnotatedMember |
_member
Member (field, method) that represents property and allows access to
associated annotations.
|
protected SerializedString |
_name
Logical name of the property; will be used as the field name under which
value for the property is written.
|
protected JavaType |
_nonTrivialBaseType
Base type of the property, if the declared type is "non-trivial"; meaning
it is either a structured type (collection, map, array), or
parameterized.
|
protected JsonSerializer<Object> |
_nullSerializer
Serializer used for writing out null values, if any: if null, null values
are to be suppressed.
|
protected JsonSerializer<Object> |
_serializer
Serializer to use for writing out the value: null if it cannot be known
statically; non-null if it can.
|
protected Object |
_suppressableValue
Value that is considered default value of the property; used for
default-value-suppression if enabled.
|
protected boolean |
_suppressNulls
Whether null values are to be suppressed (nothing written out if value is
null) or not.
|
protected TypeSerializer |
_typeSerializer
If property being serialized needs type information to be included this
is the type serializer to use.
|
protected PropertyName |
_wrapperName
Wrapper name to use for this element, if any
|
static Object |
MARKER_FOR_EMPTY
Marker object used to indicate "do not serialize if empty"

BeanPropertyWriter()
Constructor that may be of use to virtual properties, when there is need
for the zero-arg ("default") constructor, and actual initialization is
done after constructor call.
