isValid

public abstract boolean isValid(String value)

Specified by:

isValid in interface IValidation

addParam

public void addParam(String name,
            String value)

This method adds a rule parameter to the rule definition. Rule parameters are used to make configurable constant values available to the isValid() method.

Parameters:

name - String

value - String

getParamNames

protected Iterator<String> getParamNames()

Returns an iterator of the rule parameters that have been added to the validation.

Returns:

Iterator

getParamValue

protected String getParamValue(String paramName)

Returns the parameter value for the specified parameter name, or null if the parameter name does not exist.

Parameters:

paramName - String

Returns:

String

matches

protected boolean matches(String regex,
              String value)

This method gives the simplest Regular Expression interface most commonly used by validations. This method takes a regular expression and the value and determines if the value conforms to the rules established by the regular expression.

Parameters:

regex - String

value - String

Returns:

boolean
