Fast Track UML 2.0

self-transition

A transition whose source state and target state are the same.

send dependency

A dependency within which instances of the source class send signals to instances of the target class.

send object action

An action that transmits a specified object to a specified target object as a signal .

send signal action

An action that creates an instance of a specified signal and transmits this instance to a specified target object .

sequence diagram

An interaction diagram that focuses on the time ordering of messages between objects .

sequence number

A number that indicates the relative execution order of the associated message on a communication diagram .

sequential substate

A substate in which an object can reside to the exclusion of all other substates at that same level within the given composite state .

shallow history

A pseudostate that "remembers" only the outermost nested state that a given object was in before it left the enclosing composite state .

signal

A request of some kind that an object dispatches asynchronously to one or more other objects.

signal trigger

The reception of a particular signal .

simple state

A state that has no nested substates .

source

See client.

source state

The "from" state within a transition .

start owned behavior action

An action that starts the behavior owned by the object specified on a particular input pin .

state

A condition in which an object can be at some point during its lifetime, for some finite amount of time.

state invariant

A runtime constraint on a given lifeline .

state machine diagram

A diagram that shows a state machine , with the emphasis on the flow of control between states .

stereotype

A mechanism for building a modeling construct that isn't identified in the core UML but that's similar to things that are part of the core .

stop

The termination of the instance connected to a given lifeline .

structured activity node

An executable node that represents a structured portion of a given activity that isn't shared with any other structured node, except for nodes that are nested.

subclass

The more specific class within a generalization .

submachine

A state machine that can be invoked as part of one or more other state machines.

submachine state

A state that references a submachine such that a copy of that submachine is implicitly part of the enclosing state machine where the reference occurs.

substates

A state nested within a composite state .

substitution

A dependency within which the client must comply with the contract specified by the supplier at program execution time.

superclass

The more general class within a generalization .

supplier

The independent element within a dependency .

swimlane

A pair of parallel vertical or horizontal lines on an activity diagram that represent an activity partition .
