Interface ActionBeanPropertyBinder

All Superinterfaces:

ConfigurableComponent

All Known Implementing Classes:

DefaultActionBeanPropertyBinder

public interface ActionBeanPropertyBinder
extends ConfigurableComponent

Interface for class(es) responsible for taking the String/String[] properties contained in the HttpServletRequest and:

• Converting them to the rich type of the property on the target JavaBean
• Setting the properties on the JavaBean using the appropriate mechanism

Implementations may also perform validations of the fields during binding. If validation errors occur then the collection of ValidationErrors contained within the ActionBeanContext should be populated before returning.

Parameters:

bean - the ActionBean to bind the property to

propertyName - the name (including nested, indexed and mapped property names) of the property being bound

propertyValue - the value to be bound to the property on the bean

Throws:

java.lang.Exception - thrown if the property cannot be bound for any reason
