title title

An Actor models a type of role played by an entity that interacts with the subject (e.g.,

...

by

...

exchanging

...

signals

...

and

...

data),

...

but

...

which

...

is

...

external

...

to

...

the

...

subject.

...

Actors

...

may

...

represent

...

roles

...

played

...

by

...

human

...

users,

...

external

...

hardware,

...

or

...

other

...

subjects.

...

Note

...

that

...

an

...

actor

...

does

...

not

...

necessarily

...

represent

...

a

...

specific

...

physical

...

entity

...

but

...

merely

...

a

...

particular

...

facet

...

(i.e.,

...

"role")

...

of

...

some

...

entity

...

that

...

is

...

relevant

...

to

...

the

...

specification

...

of

...

its

...

associated

...

use

...

cases.

...

Thus,

...

a

...

single

...

physical

...

instance

...

may

...

play

...

the

...

role

...

of

...

several

...

different

...

actors

...

and,

...

conversely,

...

a

...

given

...

actor

...

may

...

be

...

played

...

by

...

multiple

...

different

...

instances.

...

While

...

UML

...

2

...

does

...

not

...

permit

...

associations

...

between

...

Actors,

...

this

...

constraint

...

is

...

often

...

violated

...

in

...

practice

...

since

...

the

...

generalization/specialization

...

relationship

...

between

...

actors

...

is

...

useful

...

in

...

modeling

...

overlapping

...

behaviours

...

between

...

actors.

...

  The

...

actors

...

below

...

are

...

represented

...

as

...

having

...

a

...

hierarchical

...

relationship

...

for

...

ease

...

of

...

understanding;

...

however,

...

these

...

relationships

...

can

...

easily

...

be

...

removed.
