KeyError
-
Report an error when getting the value of a non-existant KeyMap entry?
- Description:
- This attribute is a boolean value which controls how the
astMapGet...
functions behave if the requested key is not found in the KeyMap.
If KeyError is zero (the default), then these functions will return
zero
but no error will be reported. If KeyError is non-zero, then the
same values are returned but an error is also reported.
- Type:
- Integer (boolean).
- Class Applicability:
-
KeyMap
-
All KeyMaps have this attribute.
- Notes:
- When setting a new value for KeyError, the supplied value is
propagated to any KeyMaps contained within the supplied KeyMap.
- When clearing the KeyError attribute, the attribute is also
cleared in any KeyMaps contained within the supplied KeyMap.
