Description copied from interface: ValidationConstraintGenerator

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.

Specified by:

buildConstraints in interface ValidationConstraintGenerator

Parameters:

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)

Returns:

a list of constraints
