Fast Track UML 2.0

final node

A control node at which one or more flows within a given activity stop.

final state

A pseudostate that indicates that the execution of part or all of an enclosing composite state , or of an entire state machine , is complete.

flow final node

A final node that terminates a particular flow.

fork

A pseudostate that splits a transition into two or more transitions.

fork node

A control node that splits a flow into multiple concurrent flows.

gate

A connection point for relating a message outside a given interaction fragment with a message inside the fragment.

generalization

A relationship between a general class and a more specific version of that class , where the more specific class is a "kind of" the more general class.

generalization set

A specification of partitions for the subclasses of a particular superclass .

general ordering

The specification that one event occurrence must occur before another within a given interaction .

grammatical inspection

See noun/verb analysis.

guard

A Boolean expression that must resolve to True before the associated path along an activity edge can be taken.

import

A dependency within which the source package adds model elements that have public visibility from the target package.

include

A dependency within which one use case explicitly includes the behavior of another use case at a specified point within a course of action.

information flow

A dependency within which one or more information items circulate from their sources to their targets .

information item

A stereotyped class that specifies some pieces of information that can be exchanged between objects at a fairly high level of abstraction.

initial node

The activity node at which the flow of control starts when a given activity is invoked.

initial state

A pseudostate that indicates the default starting place for a transition whose target is the boundary of a state .

input pin

A pin that receives input values for an action .

instance

An object that belongs to a particular class , a link that belongs to a particular association , or a link object that belongs to a particular association class .

instantiation dependency

A dependency within which one or more methods belonging to instances of the source class create instances of the target class.

interaction

A behavior that focuses on the observable exchange of information between objects .

interaction constraint

A Boolean expression that guards an interaction operand within a combined fragment .

interaction diagram

A diagram that shows aspects of an interaction .

interaction fragment

A distinct piece of an interaction .

interaction occurrence

The occurrence of a piece of a particular interaction with specific values replacing the value placeholders defined for the interaction.

interaction operand

An operand that contains one or more interaction fragments .

interaction operator

An operator that operates on one or more interaction operands .

interaction overview diagram

An interaction diagram that focuses on the overview of the flow of control within a given interaction .

interface

A collection of operations that represent services offered by a class or a component .

intermediate action

An action primitive that carries out a computation or accesses object memory.

internal transition

A transition that leaves a given object in its current state .

interruptible activity region

An activity group that supports interrupts by terminating any tokens and behaviors connected with the activity nodes within the region when an interrupt arrives.

invariant

A constraint that specifies a condition that must always hold true under the relevant circumstances.
