BaseMixed
- class ase2sprkkr.common.grammar_types.BaseMixed(prefix=None, postfix=None, format='', default_value=None, condition=None, after_convert=None, description='')[source]
A variant type - it can hold “anything”.

Constructor
- Parameters
prefix (Optional[str]) –
postfix (Optional[str]) –
format (str) –
default_value (Any) –
condition (Optional[Callable[[Any], Union[bool, str]]]) –
after_convert (Optional[Callable[[Any], Any]]) –
- __init__(prefix=None, postfix=None, format='', default_value=None, condition=None, after_convert=None, description='')
Create the object.
- Parameters
prefix (Optional[str]) – The string, that will be printed before the value
postfix (Optional[str]) – The string, that will be printed after the value
format (str) – The (python) format string, that will be used for printing the value. The format is passed as format argument to
str.format
routine.default_value (Optional[Any]) – The default value of the options of this type.
None
means no default value.condition (Optional[Callable[[Any], Union[bool, str]]]) – Function, that check the validity of the value. It should return
True
for a valid value, andFalse
or string for invalid. The string is interpreted as an error message that explains the invalidity of the value.after_convert (Optional[Callable[[Any], Any]]) – Function, that - if it is given - is applied to the (entered or parsed) value. The function is applied on the result of the
convert
method
- type = None
The types, that the value can hold. To be redefined in the descendants.
- string_type = None
Type of string grammar_type to be used. To be redefined in the descendants.
- get_type(value)[source]
Return the type of the value. Actualy, this implementation is a simple implementation that suits for the common Mixed types, so if you make a custom Mixed type, redefine it.
