public final Class DataBindingPropertyAccessor

extends ReflectivePropertyAccessor
Class Inheritance
Imports
java.lang.reflect.Method
An org.springframework.expression.PropertyAccessor variant for data binding purposes, using reflection to access properties for reading and possibly writing.

A property can be referenced through a public getter method (when being read) or a public setter method (when being written), and also as a public field.

This accessor is explicitly designed for user-declared properties and does not resolve technical properties on java.lang.Object or java.lang.Class. For unrestricted resolution, choose ReflectivePropertyAccessor instead.
