|
Modifier and Type | Method and Description |
---|---|
boolean |
canCreateFromBoolean()
Method that can be called to check whether a double (boolean / Boolean) based
creator is available to use (to call
ValueInstantiator.createFromDouble(com.fasterxml.jackson.databind.DeserializationContext, double) ). |
boolean |
canCreateFromDouble()
Method that can be called to check whether a double (double / Double) based
creator is available to use (to call
ValueInstantiator.createFromDouble(com.fasterxml.jackson.databind.DeserializationContext, double) ). |
boolean |
canCreateFromInt()
Method that can be called to check whether an integer (int, Integer) based
creator is available to use (to call
ValueInstantiator.createFromInt(com.fasterxml.jackson.databind.DeserializationContext, int) ). |
boolean |
canCreateFromLong()
Method that can be called to check whether a long (long, Long) based
creator is available to use (to call
ValueInstantiator.createFromLong(com.fasterxml.jackson.databind.DeserializationContext, long) ). |
boolean |
canCreateFromObjectWith()
Method that can be called to check whether a property-based creator
(argument-taking constructor or factory method)
is available to instantiate values from JSON Object
|
boolean |
canCreateFromString()
Method that can be called to check whether a String-based creator
is available for this instantiator
|
boolean |
canCreateUsingDefault()
Method that can be called to check whether a default creator (constructor,
or no-arg static factory method)
is available for this instantiator
|
boolean |
canCreateUsingDelegate()
Method that can be called to check whether a delegate-based creator (single-arg
constructor or factory method)
is available for this instantiator

void |
configureFromObjectSettings(AnnotatedWithParams defaultCreator,
AnnotatedWithParams delegateCreator,
JavaType delegateType,
CreatorProperty[] delegateArgs,
AnnotatedWithParams withArgsCreator,
CreatorProperty[] constructorArgs)
Method for setting properties related to instantiating values
from JSON Object.

configureIncompleteParameter(AnnotatedParameter parameter) |
Object |
createFromBoolean(DeserializationContext ctxt,
boolean value) |
Object |
createFromDouble(DeserializationContext ctxt,
double value) |
Object |
createFromInt(DeserializationContext ctxt,
int value) |
Object |
createFromLong(DeserializationContext ctxt,
long value) |
Object |
createFromObjectWith(DeserializationContext ctxt,
Object[] args)
Method called to create value instance from JSON Object when
instantiation arguments are passed; this is done, for example when passing information
specified with "Creator" annotations.
|
Object |
createFromString(DeserializationContext ctxt,
String value) |
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 |
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). |
AnnotatedParameter |
getIncompleteParameter()
If an incomplete creator was found, this is the first parameter that
needs further annotation to help make the creator complete.
|
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).
