classmethod from_dict(input_dict)

For json deserialization, from dict instance.

Parameters:

input_dict (dict) – Appropriate parameters dict instance for deserialization

Return type:

Corresponding class instance

classmethod from_node(node, xml_ns, ns_key=None, kwargs=None)

For XML deserialization.

Parameters:

  • node (ElementTree.Element) – dom element for serialized class instance

  • xml_ns (None|dict) – The xml namespace dictionary.

  • ns_key (None|str) – The xml namespace key. If xml_ns is None, then this is ignored. If None and xml_ns is not None, then the string default will be used. This will be recursively passed down, unless overridden by an entry of the cls._child_xml_ns_key dictionary.

  • kwargs (None|dict) – None or dictionary of previously serialized attributes. For use in inheritance call, when certain attributes require specific deserialization.

Return type:

Corresponding class instance

is_valid(recursive=False, stack=False)

Returns the validity of this object according to the schema. This is done by inspecting that all required fields (i.e. entries of _required) are not None.

Parameters:

  • recursive (bool) – True if we recursively check that child are also valid. This may result in verbose (i.e. noisy) logging.

  • stack (bool) – Print a recursive error message?

Returns:

condition for validity of this element

Return type:

bool

log_validity_error(msg)

Log a validity check error message.

Parameters:

msg (str) –

log_validity_info(msg)

Log a validation info message.

Parameters:

msg (str) –

log_validity_warning(msg)

Log a validity check warning message.

Parameters:

msg (str) –

set_numeric_format(attribute, format_string)

to_dict(check_validity=False, strict=False, exclude=())

For json serialization.

Parameters:

  • check_validity (bool) – Check whether the element is valid before serializing, by calling is_valid().

  • strict (bool) – Only used if check_validity = True. In that case, if True then raise an Exception (of appropriate type) if the structure is not valid, if False then log a hopefully helpful message.

  • exclude (tuple) – Attribute names to exclude from this generic serialization. This allows for child classes to provide specific serialization for special properties, after using this super method.

Returns:

dict representation of class instance appropriate for direct json serialization.

Return type:

OrderedDict

  • tag (None|str) – The tag name. Defaults to the value of self._tag and then the class name if unspecified.

  • ns_key (None|str) – The namespace prefix. This will be recursively passed down, unless overridden by an entry in the _child_xml_ns_key dictionary.

  • parent (None|ElementTree.Element) – The parent element. Defaults to the document root element if unspecified.

  • check_validity (bool) – Check whether the element is valid before serializing, by calling is_valid().

  • strict (bool) – Only used if check_validity = True. In that case, if True then raise an Exception (of appropriate type) if the structure is not valid, if False then log a hopefully helpful message.

  • exclude (tuple) – Attribute names to exclude from this generic serialization. This allows for child classes to provide specific serialization for special properties, after using this super method.

Returns:

The constructed dom element, already assigned to the parent element.

Return type:
