assert/check/test/CountablyFinite

Validation checks to test if a given object is countablyfinite.

testCountablyFinite(object, errormsg = "This is not a countably finite set")

checkCountablyFinite(object, errormsg = "This is not a countably finite set")

assertCountablyFinite(object, errormsg = "This is not a countably finite set")

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

testCountablyFinite(Set$new(1,2,3))
#> [1] TRUE
testCountablyFinite(Interval$new(1,10))
#> [1] FALSE
