Description:

This component implements a class, ball::ThresholdAggregate, that aggregates four threshold levels: record level, pass-through level, trigger level, and trigger-all level. Each of these levels must in the range [0 .. 255], and represents a threshold which, if exceeded, will invoke a certain action.

Usage:

The following code fragment illustrates some of the basic operations on threshold levels provided by ball::ThresholdAggregate.

    ball::ThresholdAggregate levels(192, 160, 128, 96);
    assert(192 == levels.recordLevel());
    assert(160 == levels.passLevel());
    assert(128 == levels.triggerLevel());
    assert( 96 == levels.triggerAllLevel());

    levels.setLevels(160, 128, 96, 64);
    assert(160 == levels.recordLevel());
    assert(128 == levels.passLevel());
    assert( 96 == levels.triggerLevel());
    assert( 64 == levels.triggerAllLevel());
