public class FieldChecks

extends java.lang.Object

implements java.io.Serializable

This class contains the default validations that are used in the validator-rules.xml file.

In general passing in a null or blank will return a null Object or a false boolean. However, nulls and blanks do not result in an error being added to the errors.
