Constructor & Destructor Documentation

◆ bool_combiner()

cgv::signal::bool_combiner::bool_combiner ( const char *  opt)

construct from option string.

The option string can be composed of the following characters:

  • '&' ... combine with logical and
  • '|' ... combine with logical or
  • '*' ... short-circuit evaluation of boolean expression
  • '+' ... full evaluation
