Method Details

[hide private]

isAdaptable(self, ctd)

source code

A model group has an unresolvable particle if any of its particles is unresolvable. Duh.

effectiveTotalRange(self, particle)

source code

Return the minimum and maximum of the number of elements that can appear in a sequence matched by this particle.

See http://www.w3.org/TR/xmlschema-1/#cos-seq-range

init(self, compositor, particles, *args, **kw)
(Constructor)

source code

Create a new model group.

compositor must be a legal compositor value (one of C_ALL, C_CHOICE, C_SEQUENCE).

particles must be a list of zero or more Particle instances.

scope is the _ScopeDeclaration_mixin context into which new declarations are recorded. It can be SCOPE_global, a complex type definition, or None if this is (or is within) a named model group.

model_group_definition is an instance of ModelGroupDefinition if this is a named model group. It defaults to None indicating a local group.

Parameters:

scope - The scope in which the component is defined
namespace_context - The NamespaceContext to use within this component
node - If no namespace_context is provided, a DOM node must be provided from which a namespace context can be identified.
owner - Reference to the component that owns this one (the immediately enclosing component). Is None in the case of top-level components.
schema - Reference to the Schema component to which the component belongs. Required for every component except Schema, Annotation, and Wildcard.

Overrides: object.__init__

_bindingRequires_vx(self, include_lax)

source code

Placeholder for subclass method that identifies the necessary components.

Returns: frozenset

The component instances on which this component depends

Raises:

LogicError - A subclass failed to implement this method

Overrides: namespace._ComponentDependency_mixin._bindingRequires_vx

(inherited documentation)

CreateFromDOM(cls, node, **kw)
Class Method

source code

Create a model group from the given DOM node.

wxs is a Schema instance within which the model group is being defined.

node is a DOM element. The name must be one of ( 'all', 'choice', 'sequence' ), and the node must be in the XMLSchema namespace.

scope is the _ScopeDeclaration_mxin context that is assigned to declarations that appear within the model group. It can be None, indicating no scope defined, or a complex type definition.
