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
