Method that can be called to check whether a String-based creator
is available for this instantiator.

(single-arg constructor or factory method)
is available for this instantiator

canCreateXxx method
returns true: that is, if there is any way that an instance could
be created. |
ValueInstantiator |
createContextual(DeserializationContext ctxt,
BeanDescription beanDesc)
"Contextualization" method that is called after construction but before first
use, to allow instantiator access to context needed to possible resolve its
dependencies.

specified with "Creator" annotations.
|
Object |
createFromObjectWith(DeserializationContext ctxt,
SettableBeanProperty[] props,
PropertyValueBuffer buffer)
Method that delegates to
ValueInstantiator.createFromObjectWith(DeserializationContext, Object[]) by
default, but can be overridden if the application should have customized
behavior with respect to missing properties. |

String value) |
Object |
createUsingArrayDelegate(DeserializationContext ctxt,
Object delegate)
Method to called to create value instance from JSON Array using
an intermediate "delegate" value to pass to createor method
|
Object |
createUsingDefault(DeserializationContext ctxt)
Method called to create value instance from a JSON value when
no data needs to passed to creator (constructor, factory method);
typically this will call the default constructor of the value object.
|
Object |
createUsingDelegate(DeserializationContext ctxt,
Object delegate)
Method to called to create value instance from JSON Object using
an intermediate "delegate" value to pass to createor method
|

AnnotatedWithParams |
getArrayDelegateCreator()
Method that can be called to try to access member (constructor,
static factory method) that is used as the "array delegate creator".
|
JavaType |
getArrayDelegateType(DeserializationConfig config)
Method that can be used to determine what is the type of array delegate
type to use, if any; if no delegates are used, will return null.
|
AnnotatedWithParams |
getDefaultCreator()
Method that can be called to try to access member (constructor,
static factory method) that is used as the "default creator"
(creator that is called without arguments; typically default
[zero-argument] constructor of the type).
|
AnnotatedWithParams |
getDelegateCreator()
Method that can be called to try to access member (constructor,
static factory method) that is used as the "delegate creator".
|
JavaType |
getDelegateType(DeserializationConfig config)
Method that can be used to determine what is the type of delegate
type to use, if any; if no delegates are used, will return null.
|
SettableBeanProperty[] |
getFromObjectArguments(DeserializationConfig config)
Method called to determine types of instantiation arguments
to use when creating instances with creator arguments
(when
ValueInstantiator.canCreateFromObjectWith() returns true). |
Class<?> |
getValueClass()
Accessor for raw (type-erased) type of instances to create.
|
String |
getValueTypeDesc()
Method that returns description of the value type this instantiator
handles.
|
AnnotatedWithParams |
getWithArgsCreator()
Method that can be called to try to access member (constructor,
static factory method) that is used as the "non-default creator"
(constructor or factory method that takes one or more arguments).

ValueInstantiator.createFromObjectWith(DeserializationContext, Object[])
by
default, but can be overridden if the application should have customized
behavior with respect to missing properties.
The default implementation of this method uses
PropertyValueBuffer.getParameters(SettableBeanProperty[])
to read
and validate all properties in bulk, possibly substituting defaults for
missing properties or throwing exceptions for missing properties. An
overridden implementation of this method could, for example, use
PropertyValueBuffer.hasParameter(SettableBeanProperty)
and
PropertyValueBuffer.getParameter(SettableBeanProperty)
to safely
read the present properties only, and to have some other behavior for the
missing properties.
