Detailed Description

class for rising and falling edges of a stateFlag

A transition is defined in one of two ways. A general transition is defined as rising, falling, or change. A specific transition is defined by a pair of integers.

overview

The transition class defines a rising, falling or change-of-state edge. The class is designed to work in conjunction with the stateFlag class so the transitions are from one integer value to another.

In addition to specific transition defined by a pair of integers, the transition class also defines a general rising and falling edge. A third general transition called anyEdge matches any change of state. For these transitions, the exact value of the intial or final states are not specified - only the state change matters.

Examples:

hmi04.cpp.
