The
introduction
tag allows you to force an existing Java class to implement a particular
defined interface.
<introduction class="org.acme.MyClass"> <interfaces>java.io.Serializable</interfaces> </introduction>
The above declaration says that the org.acme.MyClass class will be forced to implement java.io.Serializable.
The
class
attribute can take wildcards but not boolean expressions. If you need more
complex type expressions, you can use the
expr
attribute instead.
<introduction expr="has(* *->@test(..)) OR class(org.acme.*)"> <interfaces>java.io.Serializable</interfaces> </introduction>
The
expr
can be any type expression allowed in a
typedef
expression
