public abstract class PolicySpi extends Object
Policy
class.
All the abstract methods in this class must be implemented by each
service provider who wishes to supply a Policy implementation.
Subclass implementations of this abstract class must provide
a public constructor that takes a Policy.Parameters
object as an input parameter. This constructor also must throw
an IllegalArgumentException if it does not understand the
Policy.Parameters
input.
