            _AttributeWildcard_mixin

Known Subclasses:

Support for components that accept attribute wildcards.

That is AttributeGroupDefinition and ComplexTypeDefinition. The calculations of the appropriate wildcard are sufficiently complex that they need to be abstracted out to a mix-in class.

Instance Methods

[hide private]

attributeWildcard(self)
Return the Wildcard component associated with attributes of this instance, or None if attribute wildcards are not present in the instance. source code

_setAttributeWildcard(self, attribute_wildcard)
Set the attribute wildcard property for this instance.

source code

_attributeRelevantChildren(self, node_list)
Return the nodes that are relevant for attribute processing.

source code

Inherited from cscRoot: __init__

Class Methods

Method Details

[hide private]

_attributeRelevantChildren(self, node_list)

source code

Return the nodes that are relevant for attribute processing.

Parameters:

node_list - A sequence of nodes found in a definition content information item.

Returns:

A tuple

( attributes, attributeGroups, 
          attributeWildcard)

where attributes is the subsequence of node_list that are XMLSchema attribute nodes; attributeGroups is analogous; and attributeWildcard is a single DOM node with XMLSchema name anyAttribute (or None, if no such node is present in the list).

Raises:

pyxb.SchemaValidationError - An attributeGroup node is present but does not have the required ref attribute.
pyxb.SchemaValidationError - Multiple anyAttribute nodes are identified.

CompleteWildcard(cls, namespace_context, attribute_groups, local_wildcard)
Class Method

source code

Implement the algorithm as described the specification.

Parameters:

namespace_context - The pyxb.namespace.NamespaceContext to be associated with any created Wildcard instance
attribute_groups - A list of AttributeGroupDefinition instances
local_wildcard - A Wildcard instance computed from a relevant XMLSchema anyAttribute element, or None if no attribute wildcard is relevant
