testClosed: assert/check/test/Closed

In xoopR/set6: R6 Mathematical Sets Interface

assert/check/test/Closed

Description

Validation checks to test if a given object is closed.

Usage

testClosed(object, errormsg = "This is not a closed set")

checkClosed(object, errormsg = "This is not a closed set")

assertClosed(object, errormsg = "This is not a closed 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

testClosed(Interval$new(1, 10, type = "[]"))
testClosed(Interval$new(1, 10, type = "(]"))
