Package org.kuali.rice.krad.datadictionary.validation.constraint.provider

Interface ConstraintProvider<T extends Constrainable>

Type Parameters:
T - constrainable type
All Known Implementing Classes:
AttributeDefinitionConstraintProvider, BaseConstraintProvider, ComplexAttributeDefinitionConstraintProvider, DataObjectEntryConstraintProvider
public interface ConstraintProvider<T extends Constrainable>
ConstraintProvider determines a list of constraints for a given Constrainable definition for an attribute in the data dictionary

The ConstraintProvider interface must be implemented by any class that contributes Constraints to the DictionaryValidationService. Multiple ConstraintProviders can be registered simultaneously, and each can contribute constraints for any number of constraint types.

These constraints can be looked up in a variety of ways. They may be:

  1. member variables of the Constrainable definition itself CaseConstrainable
  2. provided from some external source, or generated on the fly

The goal here is to provide a mechanism that enables implementing institutions to inject new Constraints and ConstraintProcessor classes into the DictionaryValidationService implementation via dependency injection.

  • Method Details

    • getConstraints

      List<Constraint> getConstraints(T definition, Class<? extends Constraint> constraintType)
      gets the constraints provided
      Parameters:
      definition - - a Data Dictionary definition e.g. ComplexAttributeDefinition or CollectionDefinition
      constraintType - - a java class that represents the constraint
      Returns:
      the list of constraints

    • isSupported

      boolean isSupported(Constrainable definition)
      checks whether this provider supports the provided definition
      Parameters:
      definition - - a Data Dictionary definition e.g. AttributeDefinition
      Returns:
      true if supported, false otherwise
