Method Detail

Type Parameters:

VALUE - is the generic type of the value to validate.

Returns:

the instance of this validator that always validates successfully.

validate

public ValidationFailure validate(Object value,
                                  Object valueSource)

This method validates the given value.

Parameters:

value - is the value to validate.

valueSource - is the source describing 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, the label of a widget of the UI containing the value, etc. This will help to find the problem easier. The source needs to have a reasonable string-representation as this may be displayed to the end-user to locate the source of the failure. In most cases it is suitable to directly pass a String.

Returns:

the ValidationFailure or null if the given value is valid according to this ValueValidator.
