assert/check/test/Multiset

Validation checks to test if a given object is an R6 Multiset.

testMultiset(object, errormsg = "This is not an R6 Multiset object")

checkMultiset(object, errormsg = "This is not an R6 Multiset object")

assertMultiset(object, errormsg = "This is not an R6 Multiset object")

Arguments

object	object to test
errormsg	error message to overwrite default if check fails

Value

If check passes then assert returns object invisibly and test/check return TRUE. If check fails, assert stops code with error, check returns an error message as string, and test returns FALSE.

Examples

testMultiset(Set$new(2, 3))
#> [1] FALSE
testMultiset(list(Set$new(2), Set$new(3)))
#> [1] FALSE
testMultiset(Tuple$new(2, 3))
#> [1] FALSE
testMultiset(Interval$new())
#> [1] FALSE
testMultiset(FuzzySet$new(2, 0.1))
#> [1] FALSE
testMultiset(FuzzyTuple$new(2, 0.1))
#> [1] FALSE
testMultiset(ConditionalSet$new(function(x) x == 0))
#> [1] FALSE
