活动图(activity diagram, new syntax)

JamVM中对象锁的锁定流程。

title How to lock an object in JamVM\n
start
#YellowGreen:read object's lockword;
if (object locked ?) then (yes)
    if (locked by myself ?) then (yes)
        if (lock too much times ?) then (yes)

            #YellowGreen:inflate thin lock;

类图（class diagram）

UML中类之间的关系：依赖、关联、聚合、组合、继承、实现。

@startuml class-diagram.png
scale 1.5
/'组合关系(composition)'/
class Human {
    - Head mHead;
    - Heart mHeart;
    ..
    - CreditCard mCard;
    --
    + void travel(Vehicle vehicle);
}

Human *-up- Head : contains >
Human *-up- Heart : contains >

/'聚合关系(aggregation)'/
Human o-left- CreditCard : owns >

/'依赖关系(dependency)'/
Human .down.> Vehicle : dependent

/'关联关系(association'/
Human -down-> Company : associate

/'继承关系(extention)'/
interface IProgram {
    + void program();
}
class Programmer {
    + void program();
}
Programmer -left-|> Human : extend
Programmer .up.|> IProgram : implement
