0217 Ports¶

Ports are used to define the interfaces of Processes.

• PortImplementation - at the most detailed level, a PortImplementation defines the specific interface of a process: for example, its expected inputs or produced outputs.
• PortAlias - a PortAlias provides a reference point to some other Port (either another PortAlias or a more detailed PortImplementation).
• PortDelegation - defines the parent-child relationship between Ports: for example, which PortImplementation a particular PortAlias delegates to.
• ProcessPort - defines the Port(s) that are used by a given Process as its interface(s).

Port entity¶

An interface where data flows in and/or out of a process.

• portType - Descriptor for a port that indicates the direction that data is flowing.

PortAlias entity¶

A port for a composed process whose implementation comes from the port linked via a port delegation relationship.

PortImplementation entity¶

A port with a concrete implementation.

PortDelegation relationship¶

A relationship between a parent (composed) process port and a port from a more granular process. The relationship shows where data passed to the parent process is directed.

ProcessPort relationship¶

A link between a process and one of its ports.
