Error Handling Click on the banner to return to the user guide home page. Yet think about error handling we must, in order to write robust code. The Rogue Wave class libraries all use the same extensive and complete error handling facility. Internal errors , which are further classified as either recoverable or non-recoverable, are due to errors in the internal logic of the program. As you might expect, they can be difficult to recover from and, indeed, the common default response is to abort the program.
External errors are due to events beyond the scope of the program.
Any non-trivial program should be prepared to recover from an external error. The next section presents a table that summarizes the Rogue Wave error model. The sections following the table discuss the types of errors in more detail.
