ConstrainedProperty (Grails 2.5.5.BUILD-SNAPSHOT)

org.codehaus.groovy.grails.validation.ConstrainedProperty

All Implemented Interfaces and Traits:

Constrained
```
@java.lang.SuppressWarnings("serial")
public class ConstrainedProperty
extends java.lang.Object
```
Provides the ability to set contraints against a properties of a class. Constraints can either be set via the property setters or via the
```
applyConstraint(String constraintName, Object constrainingValue)
```
in combination with a constraint constant. Example: ... ConstrainedProperty cp = new ConstrainedProperty(owningClass, propertyName, propertyType); if (cp.supportsConstraint(ConstrainedProperty.EMAIL_CONSTRAINT)) { cp.applyConstraint(ConstrainedProperty.EMAIL_CONSTRAINT, new Boolean(true)); } Alternatively constraints can be applied directly using the java bean getters/setters if a static (as oposed to dynamic) approach to constraint creation is possible: cp.setEmail(true)
