Class JsonLocationInstantiator

java.lang.Object

com.fasterxml.jackson.databind.deser.ValueInstantiator

com.fasterxml.jackson.databind.deser.std.JsonLocationInstantiator

public class JsonLocationInstantiator
extends ValueInstantiator

For JsonLocation, we should be able to just implement ValueInstantiator (not that explicit one would be very hard but...)

Method Summary

Modifier and Type	Method and Description
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
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.
CreatorProperty[]	getFromObjectArguments(DeserializationConfig config) Method called to determine types of instantiation arguments to use when creating instances with creator arguments (when ValueInstantiator.canCreateFromObjectWith() returns true).
String	getValueTypeDesc() Method that returns description of the value type this instantiator handles.

Method Detail

getValueTypeDesc

public String getValueTypeDesc()

Description copied from class: ValueInstantiator

Method that returns description of the value type this instantiator handles. Used for error messages, diagnostics.

Specified by:

getValueTypeDesc in class ValueInstantiator

canCreateFromObjectWith

public boolean canCreateFromObjectWith()

Description copied from class: ValueInstantiator

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

Overrides:

canCreateFromObjectWith in class ValueInstantiator

getFromObjectArguments

public CreatorProperty[] getFromObjectArguments(DeserializationConfig config)

Description copied from class: ValueInstantiator

Method called to determine types of instantiation arguments to use when creating instances with creator arguments (when ValueInstantiator.canCreateFromObjectWith() returns true). These arguments are bound from JSON, using specified property types to locate deserializers.

NOTE: all properties will be of type CreatorProperty.

Overrides:

getFromObjectArguments in class ValueInstantiator

createFromObjectWith

public Object createFromObjectWith(DeserializationContext ctxt,
                                   Object[] args)

Description copied from class: ValueInstantiator

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.

This method is called if ValueInstantiator.getFromObjectArguments(com.fasterxml.jackson.databind.DeserializationConfig) returns a non-empty List of arguments.

Overrides:

createFromObjectWith in class ValueInstantiator
