pyxb.binding.generate

Module generate

The really ugly code that generates the Python bindings. This whole thing is going to be refactored once customized generation makes it to the top of the task queue.

Classes

[hide private]

ReferenceLiteral
Base class for something that requires fairly complex activity in order to generate its literal value.

ReferenceFacetMember

ReferenceWildcard

_CTDAuxData
Helper class holding information need in both preparation and generation.

NamespaceModule
This class represents a Python module that holds all the declarations belonging to a specific namespace.

BuildTermTree(node)

source code

Construct a FAC term tree for a particle.

This translates the XML schema content model of particles, model groups, element declarations, and wildcards into a tree expressing the corresponding content as a regular expression with numerical constraints.

Parameters:

node - An instance of xs.structures.Particle

Returns:

An instance of pyxb.utils.fac.Node

BuildPluralityData(term_tree)

source code

Walk a term tree to determine which element declarations may appear multiple times.

The bindings need to use a list for any Python attribute corresponding to an element declaration that can occur multiple times in the content model. The number of occurrences is determined by the occurrence constraints on parent particles and the compositors of containing model groups. All this information is available in the term tree used for the content model automaton.

Parameters:

term_tree - A FAC term tree representing the content model for a complex data type.

Returns:

Plurality data, as a pair (singles, multiples) where singles is a set of base element declarations that are known to occur at least once and at most once in a region of the content, and multiples is a similar set of declarations that are known to potentially occur more than once.
