Examples of PatternValidator

• com.google.gwt.validation.client.constraints.PatternValidator
  EXPERIMENTAL and subject to change. Do not use this in production code.

  {@link Pattern} constraint validator implementation.

  Note this implementation uses {@link RegExp} which differs from{@link java.util.regex.Pattern}.

• org.apache.wicket.validation.validator.PatternValidator
  Validates a Component by matching the component's value against a regular expression pattern. A PatternValidator can be constructed with either a Java regular expression (compiled or not) or a MetaPattern. If the pattern matches against the value of the Component it is attached to when validate is called by the framework, then that input value is considered valid. If the pattern does not match, the errorMessage method will be called.

  For example, to restrict a field to only digits, you might add a PatternValidator constructed with the pattern "\d+". Another way to do the same thing would be to construct the PatternValidator passing in MetaPattern.DIGITS. The advantages of using MetaPattern over straight Java regular expressions are that the patterns are easier to construct and easier to combine into complex patterns. They are also more readable and more reusable. See {@link org.apache.wicket.util.parse.metapattern.MetaPattern MetaPattern} fordetails.

  The error message will be generated with the key "PatternValidator" and the message keys that can be used are:

  • ${pattern}: the pattern which failed to match
  • ${input}: the input the user gave
  • ${name}: the name of the Component that failed
  • ${label}: the label of the Component - either comes from FormComponent.labelModel or resource key [form-id].[form-component-id] in that order
