By arranging for objects of different types to implement common methods, we move the dispatch decision into the objects and out of an explicit conditional block.
通过安排不同类型的对象来执行公共方法，我们将分派决定移到对象中并从显式条件块中消除。

In addition to branching, decision points are supported for conditional routing based on application data.
除了分支以外，基于应用程序数据的条件传送也支持决策点。

The palette also includes basic programming constructs that allow for controlling the flow, such as decision points for conditional execution, and loops for process cycles.
