Dependency SysML

class Dependency

Implementation of Dependency defined in the KerML specification.

Specification:

A Dependency is a Relationship that indicates that one or more client Elements require one more supplier Elements for their complete specification. In general, this means that a change to one of the supplier Elements may necessitate a change to, or re-specification of, the client Elements.

Note that a Dependency is entirely a model-level Relationship, without instance-level semantics.

For language description, see section 7.2.3 of the KerML specification. For more details on the model, see section 8.3.2.2.2 of the KerML specification.

Inheritance:

• AstNode

• Element

• Relationship

Attributes

STD: tuple[type[syside.Dependency], ...] = Ellipsis

All subtypes of Dependency according to the specification.

This is needed because the implementation does not use multiple inheritance like the standard metamodel. However, all would-be inherited attributes are implemented explicitly on classes in Dependency.Std.

When working with standard metamodel types, use:

if isinstance(element, Dependency.STD):
    ...

For type hints, instead use Dependency.Std:

def function(element: Element) -> Dependency.Std:
    ...

Note that Dependency.Std is only defined during TYPE_CHECKING, depending on the Python version used either from __future__ import annotations or def function(...) -> "Dependency.Std" may be required to ensure that annotations are resolved lazily without an actual object present.

property children: syside.RelationshipBody

The elements enclosed by curly brackets in textual syntax.
