Method Detail

validate

public void validate(Object value,
                     Object valueSource)
              throws RuntimeException

This method validates the given value. If the value is invalid, a RuntimeException is thrown. Otherwise this method will return without any side-effect.

Parameters:

value - is the value to validate.

valueSource - describes the origin of the given value. This may be the filename where the value was read from, an XPath where the value was located in an XML document, etc. It can be used in exceptions thrown if the value is invalid. This will help to find the problem easier. It may be null if there is no helpful source available but you should prefer ValueValidator.validate(Object) in such case.

Throws:

RuntimeException - if the given value in invalid.
