Method Summary

Modifier and Type	Method	Description
final 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
final boolean	canInstantiate()	Method that will return true if any of canCreateXxx method returns true: that is, if there is any way that an instance could be created.
abstract 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.

Method Details

canInstantiate

public final boolean canInstantiate()

Description copied from class: ValueInstantiator

Method that will return true if any of canCreateXxx method returns true: that is, if there is any way that an instance could be created.

Overrides:

canInstantiate in class ValueInstantiator

canCreateUsingDefault

public final boolean canCreateUsingDefault()

Description copied from class: ValueInstantiator

Method that can be called to check whether a default creator (constructor, or no-arg static factory method) is available for this instantiator

Overrides:

canCreateUsingDefault in class ValueInstantiator

createUsingDefault

public abstract Object createUsingDefault(DeserializationContext ctxt)

Description copied from class: ValueInstantiator

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. It will only be used if more specific creator methods are not applicable; hence "default".

This method is called if ValueInstantiator.getFromObjectArguments(DeserializationConfig) returns null or empty List.

Overrides:

createUsingDefault in class ValueInstantiator
