Interface PermissionCheck

All Known Implementing Classes:

WebappClassLoader

public interface PermissionCheck

This interface is implemented by components to enable privileged code to check whether the component has a given permission. This is typically used when a privileged component (e.g. the container) is performing an action on behalf of an untrusted component (e.g. a web application) without the current thread having passed through a code source provided by the untrusted component. Because the current thread has not passed through a code source provided by the untrusted component the SecurityManager assumes the code is trusted so the standard checking mechanisms can't be used.

check

boolean check(java.security.Permission permission)

Does this component have the given permission?

Parameters:

permission - The permission to test

Returns:

false if a SecurityManager is enabled and the component does not have the given permission, otherwise true
