Examples of bsh.Interpreter.eval()

bsh.Interpreter.eval()
Spawn a non-interactive local interpreter to evaluate text in the specified namespace. Return value is the evaluated object (or corresponding primitive wrapper). @param sourceFileInfo is for information purposes only. It is used todisplay error messages (and in the future may be made available to the script). @throws EvalError on script problems @throws TargetError on unhandled exceptions from the script


        try {
            // use the same Interpreter (ie with the same context setup) for all evals
            Interpreter bsh = this.getBshInterpreter(context);
            for (AltTarget altTarget: this.altTargets) {
                Object retVal = bsh.eval(StringUtil.convertOperatorSubstitutions(altTarget.useWhen));
                boolean condTrue = false;
                // retVal should be a Boolean, if not something weird is up...
                if (retVal instanceof Boolean) {
                    Boolean boolVal = (Boolean) retVal;
                    condTrue = boolVal.booleanValue();
