      org.kuali.rice.krad.datadictionary.RelationshipDefinition

All Implemented Interfaces:

Serializable, DataDictionaryDefinition, org.springframework.beans.factory.InitializingBean

public class RelationshipDefinition
extends DataDictionaryDefinitionBase

A single Relationship definition in the DataDictionary, which contains information concerning which primitive attributes of this class can be used to retrieve an instance of some related Object instance The relationship element defines how primitive attributes of this class can be used to retrieve an instance of some related Object instance DD: See RelationshipDefinition.java. JSTL: relationship is a Map which is accessed using a key which is the objectAttributeName of a relationship. The map contains a single entry with a key of "primitiveAttributes" and value which is an attributesMap ExportMap. The attributesMap ExportMap contains the following keys: 0 (for first primitiveAttribute) 1 (for second primitiveAttribute) etc. The corresponding value for each entry is an primitiveAttribute ExportMap which contains the following keys: "sourceName" "targetName"

completeValidation

public void completeValidation(Class rootBusinessObjectClass,
                               Class otherBusinessObjectClass)

Directly validate simple fields, call completeValidation on Definition fields.

Parameters:

rootBusinessObjectClass - Class of the BusinessObjectEntry which ultimately contains this definition

otherBusinessObjectClass - other stuff required to complete validation

DataDictionaryEntry.completeValidation()

toString

public String toString()

Overrides:

toString in class Object

See Also:

Object.toString()

setPrimitiveAttributes

public void setPrimitiveAttributes(List<PrimitiveAttributeDefinition> primitiveAttributes)

The primitiveAttribute element identifies one pair of corresponding fields in the primary business object and the related business object. JSTL: primitiveAttribute is a Map which is accessed by the sequential key of "0", "1", etc. Each entry contains the following keys: sourceName (String) targetName (String) The value corresponding to the sourceName key is the attribute name defined for the primary business object. The value corresponding to the targetName key is the attribute name for the object being referenced by objectAttributeName.

setSupportAttributes

public void setSupportAttributes(List<SupportAttributeDefinition> supportAttributes)

Support attributes define additional attributes that can be used to generate lookup field conversions and lookup parameters. Field conversions and lookup parameters are normally generated using foreign key relationships defined within OJB and the DD. Because Person objects are linked in a special way (i.e. they may come from an external data source and not from the DB, such as LDAP), it is often necessary to define extra fields that are related to each other, sort of like a supplemental foreign key. sourceName is the name of the POJO property of the business object targetName is the name of attribute that corresponds to the sourceName in the looked up BO identifier when true, only the field marked as an identifier will be passed in as a lookup parameter at most one supportAttribute for each relationship should be defined as identifier="true"

setSourceClass

public void setSourceClass(Class<?> sourceClass)

Parameters:

sourceClass - the sourceClass to set
