Examples of org.exist.security.xacml.ExistPDP.evaluate()

org.exist.security.xacml.ExistPDP.evaluate()
The method that will be used most of the time. It provides the simplest interface to the underlying PDP by permitting the request only if the ResponseCtx includes Results that have no Obligations and only have the decision Permit. Other cases result in a PermissionDeniedException. The other cases include when an applicable policy cannot be found and when an error occurs. @param request the access request @throws PermissionDeniedException if the request is not allowed

        final XACMLSource source = expression.getSource();
        try {
            final ExistPDP pdp = context.getPDP();
            if(pdp != null) {
                final RequestCtx request = pdp.getRequestHelper().createQueryRequest(context, source);
                pdp.evaluate(request);
            }
        } catch(final PermissionDeniedException pde) {
            throw new XPathException("Permission to execute query: " + source.createId() + " denied.", pde);
