validate

public int validate(java.lang.String src,
                    int start,
                    int end)

This method does extra checking on a matched section of a String beginning at position start and ending at end. The idea is that you can do extra checking with this that you don't know how to do with a standard Regex. If this method is successful, it returns the location of the end of this pattern element -- that may be the value end provided or some other value. A negative value signifies that a match failure. By default, this method just returns end and thus does nothing.

public Validator arg(java.lang.String s)

minChars

public patInt minChars()

For optimization it is helpful, but not necessary, that you define the minimum number of characters this validator will allow to match. To do this return new patInt(number) where number is the smallest number of characters that can match.

maxChars

public patInt maxChars()

For optimization it is helpful, but not necessary, that you define the maximum number of characters this validator will allow to match. To do this either return new patInt(number), or new patInf() if an infinite number of characters may match.
