package

org.apache.commons.betwixt.expression

This package contains the system which extracts values from beans. The mapping is created by class introspection but the Expression implementations in this package inspect a particular bean instance and extract the values used to render the bean as xml.

Interfaces

Expression	`Expression` represents an arbitrary expression on a bean.
Updater	`Updater` acts like an lvalue which updates the current context bean from some text from an XML attribute or element.

CollectionUpdater	Updates a Collection by adding the new value to it.
ConstantExpression	`ConstantExpression` represents a constant expression.
Context	`Context` describes the context used to evaluate bean expressions.
DynaBeanExpression	An Expression that gets a property value from a DynaBean.
DynaBeanUpdater	Updates `DynaBean`'s.
EmptyExpression	`EmptyExpression` returns the same value as is passed in.
IteratorExpression	`IteratorExpression` returns an iterator over the current context.
MapEntryAdder	`MapEntryAdder` is used to add entries to a map.
MethodExpression	`MethodExpression` evaluates a method on the current bean context.
MethodUpdater	`MethodUpdater` updates the current bean context by calling a WriteMethod with the String value from the XML attribute or element.
StringExpression	`StringExpression` returns the current context object as a string.
