Description copied from interface: ErrorHandler

Handles an error. This method is called if the library code detects an exception that it cannot handle internally or detects another abnormal situation. At least one of e and description is guaranteed not to be null.

This method should not throw an exception, but if it does, this exception will simply be ignored.

Specified by:

handleError in interface ErrorHandler

Parameters:

context - the class that called the error handler. This information can be used to determine in which component an exception occurred if the same exception handler is registered for various components.

e - exception that was encountered by library code and could not be handled internally or null if no exception is available.

description - some additional information about the context in which the error occurred or null if no such information is available.
