Class BeanShellFactory

java.lang.Object
  com.ail.core.factory.AbstractFactory
      com.ail.core.factory.BeanShellFactory

public class BeanShellFactory
extends AbstractFactory

Factory to creat class instances from BeanShell scripts embedded in configuration. The simple contract is that a type configured to use this factory must define either a "Script" or a "Url" parameter. The factory takes this parameter's value and either uses it to download a script from in the case of Url, of uses it as the script itself in the case of "Script".

The object referred to by "type" will be retured by the factory. The type may optionally define a parameter called "extends" which names another type whose proprtyies should be merged into this type's properties. See Type.mergeDonorIntoSubject(Type, Type, Core) for a description of the rules applied during the merge. If "extends" is defined, then the object created by this script will be merged with the object created by core.newType([extends]).

In the following sample of configuration a base type called "OtherVersion" defines a type by means of the CastorBuilder. The NewVersion type "extends" OtherVersion (see the extends parameter) and then modifies the type altering the Source property.

 <type name="OtherVersion" builder="CastorBuilder" key="com.ail.core.Version">
   <patameter name="script"><![CDATA[
