Errors

When handling data from various sources there is always the risk of encountering errors during reading or writing that data. To avoid the problem of incomplete data being read or written it is necessary to handle these errors to avoid later corruption of the data. Whilst this can be done in different ways, SymbolEditor uses exceptions.

Exception Use

Exceptions are used by enclosing operations that might cause errors in a try..catch block which tries the operation and catches any exceptions that are thrown by those operations. This gives the opportunity to do any cleaning up and displaying suitable error messages.
