12.2.2.3 Attribute continuable of mbfl_exceptional_condition ¶

Given a subclass of mbfl_exceptional_condition we can use this attribute as follows:

mbfl_default_object_declare(CND)
mbfl_declare_varref(CONT)

mbfl_runtime_error_condition_make _(CND) 'someone' 'bad thing'
mbfl_exceptional_condition_continuable_var _(CONT) _(CND)
$CONT   ⇒ true

Class Attribute of mbfl_exceptional_condition_t: continuable ¶

A string representing a boolean:

‘true’

This condition is continuable: the exception can be fixed, in which case script’s execution can continue.

‘false’

This condition is non–continuable: the exception cannot be fixed, script’s execution must be terminated.

We must be careful in changing the default value of this attribute: some exceptional–conditions are meant to be non–continuable no matter what.

To cleanly terminate a script after a non–continuable exception has been raised: we can use the exit trap; Running scripts at exit–time. Location handlers can also be useful; Special location handlers.

Accessor on mbfl_exceptional_condition_t: mbfl_exceptional_condition_continuable_set CND CONTINUABLE ¶

Mutator on mbfl_exceptional_condition_t: mbfl_exceptional_condition_continuable_var CONTINUABLE_RV CND ¶

Class attribute accessor and mutator.

The parameter CONTINUABLE must be a string as accepted by mbfl_string_normalise_boolean_var(), otherwise an exceptional–condition of type mbfl_invalid_object_attrib_value_condition is raised; Normalising strings
