| ApplicationSecurityEnforcer | | public class ApplicationSecurityEnforcer (Code) | | This is a helper class which helps applications enforce secure
script execution.
It is used by the Squiggle browser as well as the rasterizer.
This class can install a SecurityManager for an application
and resolves whether the application runs in a development
environment or from a jar file (in other words, it resolves code-base
issues for the application).
