Some logical functors to build more complex queries:
true
or false
. TACondition
and TBCondition
are functors, and Chain evaluates TACondition && TBCondition
.As it's no fun to get and write the correct template arguments, convenience functions creating the correct functor are provided.
true_c
and false_c
. (provided just to match the schema) not_c
. Takes a functor as argument and returns the appropriate Not functor. chain
. Takes two functors and returns the appropriate Cain functor.
