- All Known Implementing Classes:
@UsesOrderedConfiguration(ValidationConstraintGenerator.class) public interface ValidationConstraintGeneratorInvoked to generate a list of validation constraint strings for a property. This typically involves scanning the property for annotations or naming conventions that confer the desired validation. The constraint strings are ultimately handed to
FieldValidatorSource.createValidator(org.apache.tapestry5.Field, String, String, String, org.apache.tapestry5.commons.Messages, java.util.Locale).
java.util.List<java.lang.String> buildConstraints(java.lang.Class<?> propertyType, AnnotationProvider annotationProvider)For a given property, identify all the approprite validation constraints. Each returned value is the name of a validator (i.e., "required") or a validator name and configuration (i.e., "minlength=5"). These contraints are exactly the individual terms in a
validate specification. These will ultimately be used to create
FieldValidators for the field that edits the property.
propertyType- the type of the property for which constraints are needed
annotationProvider- provides access to any annotations concerning the property (for implementations that are based on analysis of property annotations)
