set6 (version 0.2.4)

testSetList: assert/check/test/SetList

Description

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

Usage

testSetList(object, errormsg = "One or more items in the list are not Sets")
checkSetList(object, errormsg = "One or more items in the list are not Sets")
assertSetList(object, errormsg = "One or more items in the list are not Sets")

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

# NOT RUN {
testSetList(Set$new(2, 3))
testSetList(list(Set$new(2), Set$new(3)))
testSetList(Tuple$new(2, 3))
testSetList(Interval$new())
