Tests whether a "string" datatype value is between the lower and upper bound of the datatype and matches all parameters.
All tests are performed on the string value.
- 1.parameter : datatype
- 2.parameter : datatype value
- 3.parameter : lower bound of the datatype range
- 4.parameter : upper bound of the datatype range (-1 = no upper bound)
- 5.parameter : list of parameters
- return : Just "Errormessage" in case of an error, else Nothing
Tests whether a "numeric" datatype value is between the lower and upper bound of the datatype and matches all parameters.
First, the string value is parsed into a numeric representation. If no error occur, all following tests are performed on the numeric value.
- 1.parameter : datatype
- 2.parameter : datatype value
- 3.parameter : lower bound of the datatype range
- 4.parameter : upper bound of the datatype range (-1 = no upper bound)
- 5.parameter : list of parameters
- return : Just "Errormessage" in case of an error, else Nothing
Error Message for the equality test of two datatype values
- 1.parameter : datatype
- 2.parameter : datatype value
- 3.parameter : datatype value
example:
errorMsgEqual "Int" "21" "42" -> "Datatype Int with value = 21 expected, but value = 42 found"
