java.lang.Object | +--edu.utah.janosvm.resources.ClassPathResource
Provides access methods to the current team's class path.
The class path in a typical VM is used to specify where to find the class files on the local file system, however, in the JanosVM we're trying to simulate multiple JVMs so a single class path for all of the teams might be insufficient. For example, a user might want to have access to a standard and debugging build of their classes or a more paranoid user might want a team to have no class path to make sure it can't gain access to anything outside of its sandbox. Whatever the case may be, per-team class paths help maintain the illusion of multiple JVMs running in a single instance of the JanosVM.
The current implementation of the resource simply takes the class path as determined at startup and uses it as the global path from which each team can select a subset of paths. Then when a team is created you can create a ClassPathSpec with an array of strings containing the paths that the team should have access too or just use the default of everything in the global path.
