类 PropertyBasedCreator

java.lang.Object

org.codehaus.jackson.map.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.

限定符和类型	字段和说明
protected Object[]	_defaultValues If some property values must always have a non-null value (like primitive types do), this array contains such default values.
protected HashMap<String,SettableBeanProperty>	_properties 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 SettableBeanProperty[]	_propertiesWithInjectables 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 _properties, but not necessarily, when we have unnamed injectable properties.
protected ValueInstantiator	_valueInstantiator
