| 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.
- Combined (
name1.name2[index].name3(key)) -
Combining mapped, nested, and indexed references is also
supported.
