errorMsgEqual :: DatatypeName -> String -> String -> String | Source

errorMsgDataTypeNotAllowed :: String -> String -> [(String, String)] -> String -> String | Source

errorMsgDataTypeNotAllowed0 :: String -> String -> String | Source

errorMsgDataTypeNotAllowed2 :: String -> String -> String -> String -> String | Source

errorMsgDataLibQName :: String -> String -> String -> String | Source

errorMsgParam :: LocalName -> String -> String -> String | Source

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"

rng_maxLength :: String | Source

rng_minLength :: String | Source

type FunctionTable = [(String, String -> String -> Bool)] | Source

Function table type

stringValidFT :: FunctionTable -> DatatypeName -> Integer -> Integer -> ParamList -> CheckString | Source

fctTableString :: FunctionTable | Source

Function table for string tests, XML document value is first operand, schema value second

fctTableList :: FunctionTable | Source

Function table for list tests, XML document value is first operand, schema value second

stringValid :: DatatypeName -> Integer -> Integer -> ParamList -> CheckString | Source

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 : lower bound of the datatype range
- 3.parameter : upper bound of the datatype range (-1 = no upper bound)
- 4.parameter : list of parameters
- 5.parameter : datatype value to be checked
- return : Just "Errormessage" in case of an error, else Nothing

numberValid :: DatatypeName -> Integer -> Integer -> ParamList -> CheckString | Source

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 : lower bound of the datatype range
- 3.parameter : upper bound of the datatype range (-1 = no upper bound)
- 4.parameter : list of parameters
- 5.parameter : datatype value to be checked
- return : Just "Errormessage" in case of an error, else Nothing

numParamValid :: (Integer -> Integer -> Bool) -> String -> String -> Bool | Source

tests whether a string value matches a numeric param

valid example:

     <data type="CHAR"> <param name="maxLength">5</param> </data>

invalid example:

     <data type="CHAR"> <param name="minLength">foo</param> </data>

data CheckA a b | Source

Instances

Arrow CheckA
ArrowZero CheckA
ArrowPlus CheckA
Category CheckA

type CheckString = CheckA String String | Source

type CheckInteger = CheckA Integer Integer | Source

performCheck :: CheckA a b -> a -> Maybe String | Source

run a check and deliver Just an error message or Nothing

ok :: CheckA a a | Source

every thing is fine

failure :: (a -> String) -> CheckA a b | Source

always failure

assert :: (a -> Bool) -> (a -> String) -> CheckA a a | Source

perform a simple check with a predicate p, when the predicate holds, assert acts as identity, else an error message is generated

assertMaybe :: (a -> Maybe b) -> (a -> String) -> CheckA a b | Source

perform a simple check with a Maybe function, Nothing indicates error

checkWith :: (a -> b) -> CheckA b c -> CheckA a a | Source

perform a check, but convert the value before checking
