All Implemented Interfaces:

java.lang.Cloneable

public final class ClassPathSpec

extends ResourceSpec

implements java.lang.Cloneable

Specification for the class path resource. Used to specify the classpath for a new team. The given classpath is used to load new classes in the team, but is not used for shared classes (those specified via the NameSpaceSpec).

A ClassPathSpec is comprised of Strings, one for each element. Only globally valid class path elements (see ClassPathResource) can be used (otherwise an ResourceException will be thrown by the team constructor). A null or empty ClassPathSpec is valid (it implies the new team cannot load any classes and can only use imported classes).

If not specified, the default class path for a new Team is the full class path of the JVM.
