Class PropertyBasedCreator

java.lang.Object

com.fasterxml.jackson.databind.deser.impl.PropertyBasedCreator

public final class PropertyBasedCreator
extends Object

Object that is used to collect arguments for non-default creator (non-default-constructor, or argument-taking factory method) before creator can be called. Since ordering of JSON properties is not guaranteed, this may require buffering of values other than ones being passed to creator.

Field Summary

Fields

Modifier and Type	Field and Description
protected SettableBeanProperty[]	_allProperties Array that contains properties that expect value to inject, if any; null if no injectable values are expected.
protected int	_propertyCount Number of properties: usually same as size of _propertyLookup, but not necessarily, when we have unnamed injectable properties.
protected HashMap<String,SettableBeanProperty>	_propertyLookup Map that contains property objects for either constructor or factory method (whichever one is null: one property for each parameter for that one), keyed by logical property name
protected ValueInstantiator	_valueInstantiator Helper object that knows how to actually construct the instance by invoking creator method with buffered arguments.

_propertyLookup

protected final HashMap<String,SettableBeanProperty> _propertyLookup

Map that contains property objects for either constructor or factory method (whichever one is null: one property for each parameter for that one), keyed by logical property name

_allProperties

protected final SettableBeanProperty[] _allProperties
