Synopsis

This is the base class for all of the Casacore error classes. Because all of the errors have a common base class, any error can be caught with a single catch statement.

This class has a string which allows error messages to be propagated.

Tip: The string member must be handled very carefully because string is also derived from cleanup, thus the message;makePermanent() call in the implementation of the constructors; This prevents the String from being cleaned up in the middle of an exception;

Example

throw(AipsError("SOME STRING"));

static

Repackage an exception.

void casacore::AipsError::setMessage ( const String &  msg ) const

inline

Append a message.

This is used by LogIO when an exception is logged. The message is const to be able to use it for a temporary exception.

static

Throw if the system error code is not 0.
