轻量级UML工具-UMLet

免费、开源，而且灰常好用的工具，这里就当加一个备注。免得忘了

如何在UMLet中表示static和final？

UMLet中表示static用下划线（对于method、function或者operation也用下划线代表static），个人感觉可以用斜体来表示final（对于method、function或者operation斜体代表abstract），如图

代码如下：

rball::BulletGenerator
--
-bullet: Sphere
-bulletSize: float
-bulletCollisionShape: SphereCollisionShape
// 用下划线表示static，用斜体表示final
/_-DEFAULT_initSpeeds: float[]_/
-initSpeed: float
-initSpeedIndex: int

-cam: Camera
-mat: Material
-rootNode: Node
-bulletAppState: BulletAppState
--
+BulletGenerator(
    cam: Camera
    mat: Material
    rootNode: Node
    bulletAppState: BulletAppState): BulletGenerator
--
~getInitSpeed(): float
~nextInitSpeed(): void
~previousInitSpeed(): void
~launchBullet(): void
-getPhysicsSpace(): PhysicsSpace

再如图：

代码：

/SimpleApplication/
--
/+simpleInitApp(): void/
+simpleUpdate(tpf: float): void
+simpleRender(rm: RenderManager): void

rball::GameMain
--
~bulletGenerator: BulletGenerator
~matBullet: Material

-bulletSpeedText: BitmapText
~bulletSpeedTextListener BulletSpeedTextListener

~positionBallGenerator: BallGenerator
~randomBallGenerator: BallGenerator

~terrain: TerrainQuad
~matRock: Material
~matWire: Material

~wireframe: boolean

#hintText: BitmapText

-bulletAppState: BulletAppState
--
_+main(args: String[])_
+setupKeys()
+simpleInitApp()
+simpleUpdate(tpf: float)

-initCrossHairs()
-loadHintText()
-loadBulletSpeedText()

-getWorldIntersection(): Vector3f
-isInRadius(x: float, y: float, radius: float): boolean
-calculateHeight(radius: float, heightFactor: float, x: float, z: float): float
-adjustHeight(loc: Vector3f, radius: float, height: float)

UML类图中可见性（参考这里）：

　　public: +

　　protected: #

　　private: -

　　package: ~

类图中，如果function的返回值为void怎么处理？

不要画为function(): void，直接画为function()即可
