STRICTMAPPER

mapper

Wraps a mapper in such a way that the mapper will only be called if the number of ticks in the window is in the specified range.

Since 2.1 STRICTMAPPER can also take a timespan definition by inputing negative numbers. Number of ticks and timespan can also be mixed to specify, for instance, more than 2 points but less than 5 seconds.

STRICTMAPPER is available since version 1.0.0.
