Exception chaining

Exception chaining is the process of designing and implementing exception handlings in an application so that individual Exception handling can be handled by one or more handlers in a Hierarchy (object-oriented programming) manner. For example, in an object-oriented programming model, nested objects may receive exceptions at the lowest level. The object decides if it needs to handle the exception, and, if needed, can reraise the exception, sending it up the line. One example of the usefulness of this technique is mouse click handling. If there is a need to dynamically control what object responds to a click, exception chaining is usually the most efficient way to accomplish this.
