org.jgroups.stack.Policy Maven / Gradle / Ivy
Go to download
This artifact provides a single jar that contains all classes required to use remote EJB and JMS, including
all dependencies. It is intended for use by those not using maven, maven users should just import the EJB and
JMS BOM's instead (shaded JAR's cause lots of problems with maven, as it is very easy to inadvertently end up
with different versions on classes on the class path).
The newest version!

/**
* A policy implementation checks that a condition is met or throws an exception if not. A condition could be for
* example the check if a given protocol is present, an attribute is within a given range etc.
*
* Policies are called after {@link Protocol#init()}, so the protocol is full initialized (all attrs and components
* are set).
