Sequence
- class ase2sprkkr.common.grammar_types.arrays.Sequence(*types, format='', format_all=False, allowed_values=None, default_values=False, names=None, **kwargs)[source]
A sequence of values of given types
Class hierarchy
Constructor
- __init__(*types, format='', format_all=False, allowed_values=None, default_values=False, names=None, **kwargs)[source]
Create the object.
- Parameters:
prefix – The string, that will be printed before the value
postfix – The string, that will be printed after the value
format – The (python) format string, that will be used for outputing the value. The format is passed as format argument to
str.format
routine.after_format – In some cases, the additional formating is required after converting to the string and adding postfix/prefix.
default_value – The default value of the options of this type.
None
means no default value.condition – 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 – 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
- grammar_name()[source]
Human readable expression of the grammar. By default, this is what is set by grammar.setName, however, sometimes is desirable to set even shorter string
- _string(val)[source]
Convert the value to the ouput.
The
string()
apply format and do some additional transformation (add prefix, postfix etc.), so the actual way how to convert the value for the output should be here.
- enrich(option)[source]
Some types can add properties to the options that have the type, e.g. see Sequence.enrich, which adds the ability to access the items of the sequence using []
- static is_the_same_value(a, b)
The numpy arrays cannot be compared by =, that’s why this method. However, the method is still far from to be perfect, it can not compare nested numpy arrays.
