UML sixth operation: analysis system, FIG draw order
First, the operational requirements and procedures
step1: Learning sequence mapping method PlantUML
step2: the "factory procurement" system, for example, analysis of objects in the system message.
step3: Referring to FIG materials P148 8.5 page analysis of the interactive objects;
step4: use PlantUML "factory sourcing" object interaction script systems;
step5: online draw UML diagrams
First, the activity diagram syntax
Activities tab (activity label) begins with a colon, a semicolon ends the text format support creole wiki syntax. Default installation of the sequence of activities that define the line connection.
@startuml
:Hello world;
:This is on defined on
several **lines**;
@enduml
start end
You can use keywords startand stopstart and end indicate shown.
@startuml
start
:Hello world;
:This is on defined on
several **lines**;
stop
@enduml
You can also use end keywords.
@startuml
start
:Hello world;
:This is on defined on
several **lines**;
end
@enduml
Conditional statements
In the illustration you can use keywords if, thenand elsesetting the test branch. The dimension text in parentheses.
@startuml
start
if (Graphviz installed?) then (yes)
:process all\ndiagrams;
else (no)
:process only
__sequence__ and __activity__ diagrams;
endif
stop
@enduml
You can also use the keyword elseifset up multiple branches tests.
@startuml
start
if (condition A) then (yes)
:Text 1;
elseif (condition B) then (yes)
:Text 2;
stop
elseif (condition C) then (yes)
:Text 3;
elseif (condition D) then (yes)
:Text 4;
else (nothing)
:Text else;
endif
stop
@enduml
Repeat cycle
You can use keywords repeatand repeatwhilerepeat the cycle.
@startuml
start
repeat
:read data;
:generate diagrams;
repeat while (more data?)
stop
@enduml
可以使用关键字while和end while进行while循环。
@startuml
start
while (data available?)
:read data;
:generate diagrams;
endwhile
stop
@enduml
还可以在关键字endwhile后添加标注，还有一种方式是使用关键字is。
@startuml
while (check filesize ?) is (not empty)
:read file;
endwhile (empty)
:close file;
@enduml
并行处理
可以使用关键字fork，fork again和end fork表示并行处理。
@startuml
start
if (multiprocessor?) then (yes)
fork
:Treatment 1;
fork again
:Treatment 2;
end fork
else (monoproc)
:Treatment 1;
:Treatment 2;
endif
@enduml
注释
文本格式支持creole wiki语法。
A note can be floating, using floating keyword.
@startuml
start
:foo1;
floating note left: This is a note
:foo2;
note right
This note is on several
//lines// and can
contain <b>HTML</b>
====
* Calling the method ""foo()"" is prohibited
end note
stop
@enduml
颜色
可以为活动(activity)指定一种颜色。
@startuml
start
:starting progress;
#HotPink:reading configuration files
These files should edited at this point!;
#AAAAAA:ending of the process;
@enduml
箭头
使用->标记，可以给箭头添加文字或者修改箭头颜色。
同时，也可以选择点状 (dotted)，条状(dashed)，加粗或者是隐式箭头
@startuml
:foo1;
-> You can put text on arrows;
if (test) then
-[#blue]->
:foo2;
-[#green,dashed]-> The text can
also be on several lines
and **very** long...;
:foo3;
else
-[#black,dotted]->
:foo4;
endif
-[#gray,bold]->
:foo5;
@enduml
连接器(Connector)
可以使用括号定义连接器。
@startuml
start
:Some activity;
(A)
detach
(A)
:Other activity;
@enduml
组合(grouping)
通过定义分区(partition)，你可以把多个活动组合(group)在一起。
@startuml
start
partition Initialization {
:read config file;
:init internal variable;
}
partition Running {
:wait for user interaction;
:print information;
}
stop
@enduml
泳道(Swimlanes)
你可以使用管道符|来定义泳道。
还可以改变泳道的颜色。
@startuml
|Swimlane1|
start
:foo1;
|#AntiqueWhite|Swimlane2|
:foo2;
:foo3;
|Swimlane1|
:foo4;
|Swimlane2|
:foo5;
stop
@enduml
分离(detach)
可以使用关键字detach移除箭头。
@startuml
:start;
fork
:foo1;
:foo2;
fork again
:foo3;
detach
endfork
if (foo4) then
:foo5;
detach
endif
:foo6;
detach
:foo7;
stop
@enduml
特殊领域语言(SDL)
通过修改活动标签最后的分号分隔符(;)，可以为活动设置不同的形状。
|<>/]}
@startuml
:Ready;
:next(o)|
:Receiving;
split
:nak(i)<
:ack(o)>
split again
:ack(i)<
:next(o)
on several line|
:i := i + 1]
:ack(o)>
split again
:err(i)<
:nak(o)>
split again
:foo/
split again
:i > 5}
stop
end split
:finish;

2、到订货界面，接收客户信息，接收货品信息，显示货品信息
3、到订货管理器，创建客户，取货品信息，创建订单
4、创建客户到客户区，取货品信息到货品区，创建订单到订单区
actor 采购员

participant "订单" as E

A -> B:接收货品信息()
activate B
