Classes

RingParam(family_name, energy[, periodicity])

Private class for Matlab RingParam element

element_from_dict(elem_dict, index=None, check=True, quiet=False)

Builds an Element from a dictionary of attributes

Parameters:

• elem_dict (dict) – Dictionary of element attributes

• index (Optional[int]) – Element index

• check (bool) – Check the compatibility of class and PassMethod

• quiet (bool) – Suppress the warning for non-standard classes

Returns:

elem (Element) – new Element

element_from_m(line)

Builds an Element from a line in an m-file

Parameters:

line (str) – Matlab string representation of an Element

Returns:

elem (Element) – new Element

element_from_string(elem_string)

Builds an Element from its python repr() string

Parameters:

elem_string (str) – String representation of an Element

Returns:

elem (Element) – new Element

element_to_dict(elem)

Builds the Matlab structure of an Element

Parameters:

elem (Element) – Element

Returns:

dct (dict) – Dictionary of Element attributes

element_to_m(elem)

Builds the Matlab-evaluable string for an Element

Parameters:

elem (Element) – Element

Returns:

mstr (str) – Matlab string representation of the Element attributes

find_class(elem_dict, quiet=False)

Identify the class of an element from its attributes

Parameters:

• elem_dict (dict) – The dictionary of keyword arguments passed to the Element constructor.

• quiet (bool) – Suppress the warning for non-standard classes

Returns:

element_class – The guessed Class name

find_class_name(elem_dict, quiet=False)

Derive the class name of an Element from its attributes

hasattrs(kwargs, *attributes)

Checks the presence of keys in a dict

Returns True if any of the attributes is in kwargs

Parameters:

• kwargs (dict) – The dictionary of keyword arguments passed to the Element constructor.

• attributes – A list of strings, the attribute names to be checked.

Returns:

found (bool) – True if the element has any of the specified attributes.
