node.ext.uml.utils

Convinience for every day tasks to work with the UML.

API

class node.ext.uml.utils.Inheritance(context)

Bases: node.base.OrderedNode

Tree giving the inheritance tree point of view of arbitary UML-elements.

By adapting an UML element this tree shows the generelizations of the element as a Node tree.

On __getitem__ it returns the Inheritance adapter of the more general element.

all

flattend (list) from the traversed tree of more general UML-elements.

@return: list of UMLElements.

iterkeys()

iterates over uuids of more general UML-elements.

itervalues()

iterates over more general UML-elements.

noderepr

class node.ext.uml.utils.Inheritors(context)

Bases: object

Adapter giving the inverse inheritance point of view of arbitary UML-elements.

all

UMLElements which are inheriting (less general) from the given UMLElement, following the tree down: childs of childs are included.

@return: list of UMLElements.

direct

UMLElements which are inheriting diretcly (less general) from the given UMLElement

@return: list of UMLElements.

class node.ext.uml.utils.Associations(context)

Bases: object

Adapter to get information about an UMLElements associations.

all

All associations: direct, directlyrealized, inherited and inheritedrealized.

return

list of AssociationEnd instances.

direct

All associations which are starting or ending directly at the given UML element.

@return: list of AssociationEnd instances.

directlyrealized

All associations which are on Interfaces with InterfaceRealizations directly on this UMLElement. This includes Associations from more general Interfaces of the contracted Interface (it takes the Inheritance tree of the Relaized interface into account).

@return: list of AssociationEnd instances.

inherited

All associations which are inherited from more general UML-Elements, the direct associations are not included.

@return: list of AssociationEnd instances.

inheritedrealized

All associations which are on Interfaces with InterfaceRealizations from more general UMLElements of this element. This includes Associations from more general Interfaces of the contracted Interface (it takes the Inheritance tree of the Relaized interface into account). It does not include directly realized associations.

@return: list of AssociationEnd instances.

class node.ext.uml.utils.Aggregations(context)

Bases: node.ext.uml.utils.Associations

Adapter to get information about an UMLElements aggregations.

class node.ext.uml.utils.Aggregators(context)

Bases: node.ext.uml.utils.Associations

Adapter to get information about an UMLElements aggregators.

This is done by adding a filter so the inherited methods of this class instances are taking onyl aggregations into account.

allparticipants

All UMLElements the AssociationEnds of all are pointing to.

return

list of UMLElements

class node.ext.uml.utils.TaggedValues(context)

Bases: object

Adapter to get information about an UMLElements TaggedValues.

direct(tag, stereotype=None, default=<object object at 0x444e650>)

Access only tgvs directly applied through stereotypes on element.

tag

The name of the tag to fetch the value from. If no stereotype argument is given it is expected here in the form: STEREOTYPE:TAG.

stereotype

Name of the stereotype. Can be omitted if it is part of tag argument.

return

some value

inherited(tag, stereotype=None, alternatives=[], aggregate=True)

Access tgvs on this element and more general elements of element.

tag

The name of the tag to fetch the value from. If no stereotype argument is given it is expected here in the form: STEREOTYPE:TAG.

stereotype

Name of the stereotype. Can be omitted if it is part of tag argument.

alternatives

Look in more general elements also for stereotypes/tags in this list. Expects either a tuple tag, stereotype or a tag prefixed with stereotype as described above. Lookup order: arguments, order of list, first one hit wins.

aggregate

When True a list of all found values is returned. Otherwise it stops on the first matching tag and returns its value.

return

A value, or in case of aggregate a list of values.

namespaced(tag, stereotype=None, alternatives=[], aggregate=True)

Access tgvs on this element and elements down in namespace.

tag

The name of the tag to fetch the value from. If no stereotype argument is given it is expected here in the form: STEREOTYPE:TAG.

stereotype

Name of the stereotype. Can be omitted if it is part of tag argument.

alternatives

Look in more general elements also for stereotypes/tags in this list. Expects either a tuple tag, stereotype or a tag prefixed with stereotyoe as described above.

aggregate

When True a list of all found values is returned. Otherwise it stops on the first matching tag and returns its value.

return

A value, or in case of aggregate a list of values.
