Digxel_test Class Reference

Description

Test:

verify correct behaviour of an display "Digxel": A self-contained numeric element to support building displays.

• build a Digxel
• set a value
• retrieve formatted display
• verify comparisons and increments
• performing side-effects from the setter-functor
• formatted value caching

verifyAssignMutatingOperators()

void verifyAssignMutatingOperators ( )

inlineprivate

Test:

verify the self-assigning increment/decrement operators.

Note

especially these need to invoke the mutator function, much like a direct assignment. We use a special mutator to protocol the previous / new value.

Here is the caller graph for this function:

timingMeasurements()

void timingMeasurements ( )

inlineprivate

Test:

perform several timing measurements and especially verify the effect of caching formatted values. Digxel avoids reformatting unchanged values; besides that it is possible to install a "mutator" functor for invoking all kinds of special behaviour on value changes. Of course doing so comes with a (considerable) price tag....

Note

the measurement especially show the effects of locality, which can vary largely over several runs.
