Interface ShellJavaScriptHost

All Known Implementing Classes:

ModuleSpace, ModuleSpaceOOPHM

public interface ShellJavaScriptHost

This interface contains all of the methods that must be exposed to a hosted mode application via its JavaScriptHost class. JavaScriptHost contains a method called setHost() that must be called when a new application is initialized. This interface works with JavaScriptHost to keep running applications at arms-length via an isolated class loader (this requires that there be no explicit dependencies between the shell and any client-side classes).
