Table
- class ase2sprkkr.common.grammar_types.Table(columns=None, header=None, free_header=False, format={<class 'float'>: '>21.17', None: '>16'}, format_all=True, numbering=None, numbering_label=None, numbering_format=True, prefix=None, postfix=None, length=None, row_condition=None, default_values=False, named_result=False, **kwargs)[source]
Table, optionaly with named columns, e.g.
::text
- IQ IREFQ IMQ NOQ ITOQ CONC

Constructor
- __init__(columns=None, header=None, free_header=False, format={<class 'float'>: '>21.17', None: '>16'}, format_all=True, numbering=None, numbering_label=None, numbering_format=True, prefix=None, postfix=None, length=None, row_condition=None, default_values=False, named_result=False, **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 printing the value. The format is passed as format argument to
str.format
routine.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
- name_in_grammar = False
Default value for ValueDefinition.name_in_grammar. Some types (e.g. Tables) commonly have no name (are identified by its position in the potential file) – such type could redefine this class property.
- _string(data)[source]
The string method do some additional transformation (add prefix, postfix etc.), so the actual way how to convert the value for the output should be here.
- property numpy_type
The base class of the class hierarchy.
When called, it accepts no arguments and returns a new featureless instance that has no instance attributes and cannot be given any.
- zero_data(length)[source]
Return array of zeros with the given number of rows and with the dtype of the table
- 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
- 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.
