PropertyAccessor interface.

implementation of actual property access left to subclasses.getPropertyValue(java.lang.String),

| Modifier and Type | Method and Description |
|---|---|
Class<?> |
getPropertyType(String propertyPath)
Determine the property type for the given property path.
|
abstract Object |
getPropertyValue(String propertyName)
Actually get the value of a property.
|
boolean |
isAutoGrowNestedPaths()
Return whether "auto-growing" of nested paths has been activated.
|
boolean |
isExtractOldValueForEditor()
Return whether to extract the old property value when applying a
property editor to a new value for a property.
|
void |
setAutoGrowNestedPaths(boolean autoGrowNestedPaths)
Set whether this instance should attempt to "auto-grow" a
nested path that contains a
null value. |
void |
setExtractOldValueForEditor(boolean extractOldValueForEditor)
Set whether to extract the old property value when applying a
property editor to a new value for a property.
|
void |
setPropertyValue(PropertyValue pv)
Set the specified value as current property value.
|
abstract void |
setPropertyValue(String propertyName,
Object value)
Actually set a property value.
|
void |
setPropertyValues(Map<?,?> map)
Perform a batch update from a Map.
|
void |
setPropertyValues(PropertyValues pvs)
The preferred way to perform a batch update.
|
void |
setPropertyValues(PropertyValues pvs,
boolean ignoreUnknown)
Perform a batch update with more control over behavior.
|
void |
setPropertyValues(PropertyValues pvs,
boolean ignoreUnknown,
boolean ignoreInvalid)
Perform a batch update with full control over behavior.

If true, a null path location will be populated
with a default object value and traversed instead of resulting in a
NullValueInNestedPathException.
Default is false on a plain PropertyAccessor instance.

PropertyAccessorBulk updates from PropertyValues are more powerful: This method is
provided for convenience. Behavior will be identical to that of
the PropertyAccessor.setPropertyValues(PropertyValues) method.

PropertyAccessorNote that performing a batch update differs from performing a single update,
in that an implementation of this class will continue to update properties
if a recoverable error (such as a type mismatch, but not an
invalid field name or the like) is encountered, throwing a
PropertyBatchUpdateException containing all the individual errors.
This exception can be examined later to see all binding errors.
Properties that were successfully updated remain changed.
Does not allow unknown fields or invalid fields.

PropertyEditorRegistrySupportCalled by PropertyEditorRegistrySupport.findCustomEditor(java.lang.Class<?>, java.lang.String) if no required type has been specified,
to be able to find a type-specific editor even if just given a property path.
The default implementation always returns null.
BeanWrapperImpl overrides this with the standard getPropertyType
method as defined by the BeanWrapper interface.
