public class NameResolver
extends java.lang.Object
```
base on org.apache.commons.beanutils.expression.DefaultResolver
Default Property Name Expression Resolver Implementation.
This class assists in resolving property names in the following five formats, with the layout of an identifying String in parentheses:
- Simple (name) - The specified name identifies an individual property of a particular JavaBean. The name of the actual getter or setter method to be used is determined using standard JavaBeans instrospection, so that (unless overridden by a BeanInfo class, a property named "xyz" will have a getter method named getXyz() or (for boolean properties only) isXyz(), and a setter method named setXyz().
- Nested (name1.name2.name3) The first name element is used to select a property getter, as for simple references above. The object returned for this property is then consulted, using the same approach, for a property getter for a property named name2, and so on. The property value that is ultimately retrieved or modified is the one identified by the last name element.
- Indexed (name[index]) - The underlying property value is assumed to be an array, or this JavaBean is assumed to have indexed property getter and setter methods. The appropriate (zero-relative) entry in the array is selected. List objects are now also supported for read/write. You simply need to define a getter that returns the List
- Mapped (name(key)) - The JavaBean is assumed to have an property getter and setter methods with an additional attribute of type java.lang.String.
- Search (users(name=tom)) - The JavaBean is assumed to have an property getter and setter methods with an additional attribute of type java.lang.String.
- Combined (name1.name2[index].name3(key).users[name=n2]) - Combining mapped, nested, and indexed references is also supported.
