Detailed Description

Class to handle errors and exceptions in a simple, consistent stream-based manner.

The error class is globally instantiated with a title string. Errors, messages and other data are piped to the messageStream class in the standard manner. Manipulators are supplied for exit and abort which may terminate the program or throw an exception depending on whether the exception handling has been switched on (off by default).

Usage

error << "message1" << "message2" << FoamDataType << exit(errNo);
error << "message1" << "message2" << FoamDataType << abort();
