Example 2 with AppInfoException

use of com.jopdesign.common.misc.AppInfoException in project jop by jop-devel.

the class WCETTool method rebuildCallGraph.

    	 * does NOT have an empty callstring
    	 */

    /* Instead, we create a new "subgraph" based on the appInfo callgraph (which has been created using
         * DFA results if available in initialize() or by some other tool), where the target method has an empty
         * callstring, using the callstring length configured for the WCET tool (which is currently the same
         * as the global setting).
