assert/check/test/Interval

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

testInterval(object, errormsg = "This is not an R6 Interval object")

checkInterval(object, errormsg = "This is not an R6 Interval object")

assertInterval(object, errormsg = "This is not an R6 Interval 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

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