DatabricksValidationException

checkIfPositive

public static <T extends Number> void checkIfPositive(T number,
                                                      String fieldName)
                                               throws DatabricksValidationException

Validates that a number is positive (greater than 0).

Parameters:

number - the number to validate

fieldName - the name of the field being validated

Throws:

DatabricksValidationException - if the number is not positive

validateAndParsePositiveInteger

public static int validateAndParsePositiveInteger(String value,
                                                  String fieldName)
                                           throws DatabricksValidationException

Parameters:

value - the string value to parse

fieldName - the name of the field being validated

Returns:

the parsed positive integer

Throws:

DatabricksValidationException - if the value cannot be parsed or is not positive

throwErrorIfNull

public static void throwErrorIfNull(Map<String,String> fields,
                                    String context)
