Detailed Description

An error facility routes a group of errors handled in a similar manner.

To group handling of erc objects, each erc has associated a facility.

Instead of throwing an exception directly, the erc calls the facility's raise function. In turn, it is this function that decides what should happen erc based on facility's log level and throw level.

There is also a default facility that is used when the erc doesn't have an explicit facility.

Member Function Documentation

Default()

void mlib::errfac::Default ( errfac *  facility )

inlinestatic

set default facility

Change the default error facility.

If called with a NULL argument reverts to generic error facility

log()

void mlib::errfac::log ( const erc &  e ) const

inlinevirtual

Logging action. Default is to use stderr Message is "<facility name> - <erc message>\n"

Reimplemented in mlib::sock_facility.

message()

std::string mlib::errfac::message ( const erc &  e ) const

inlinevirtual

return message to be logged

Default message is "error <code>".

Reimplemented in mlib::sock_facility.

raise()

void mlib::errfac::raise ( const erc &  e ) const

inlinevirtual

Check if error must be logged or thrown.

This function is called by an active error (in destructor of erc objects or assignment operator).

The typical action chain is: erc destructor -> errfac::raise -> erc is thrown
