AQMP Error Classes
QMP Error Classes
This package seeks to provide semantic error classes that are intended
to be used directly by clients when they would like to handle particular
semantic failures (e.g. "failed to connect") without needing to know the
enumeration of possible reasons for that failure.
AQMPError serves as the ancestor for all exceptions raised by this
QMPError serves as the ancestor for all exceptions raised by this
package, and is suitable for use in handling semantic errors from this
library. In most cases, individual public methods will attempt to catch
and re-encapsulate various exceptions to provide a semantic
error-handling interface.
