All Implemented Interfaces:

Serializable, Inquirable, ViewHelperService

Direct Known Subclasses:

KualiInquirableImpl, PeopleFlowInquirableImpl, RuleStudentInquiryViewHelperServiceImpl

public class InquirableImpl
extends ViewHelperServiceImpl
implements Inquirable

Implementation of the Inquirable interface that uses metadata from the data dictionary and performs a query against the database to retrieve the data object for inquiry

More advanced lookup operations or alternate ways of retrieving metadata can be implemented by extending this base implementation and configuring

Field Detail

dataObjectClass

protected Class<?> dataObjectClass

SUPER_CLASS_TRANSLATOR_LIST

public static List<Class<?>> SUPER_CLASS_TRANSLATOR_LIST

A list that can be used to define classes that are superclasses or superinterfaces of kuali objects where those objects' inquiry URLs need to use the name of the superclass or superinterface as the business object class attribute

Constructor Detail

InquirableImpl

public InquirableImpl()

Method Detail

retrieveDataObject

public Object retrieveDataObject(Map<String,String> parameters)

Finds primary and alternate key sets configured for the configured data object class and then attempts to find a set with matching key/value pairs from the request, if a set is found then calls the module service (for EBOs) or business object service to retrieve the data object

Note at this point on business objects are supported by the default implementation

Specified by:

retrieveDataObject in interface Inquirable

Parameters:

parameters - - a map of string field names and values

Returns:

the data object or null if not found

See Also:

Inquirable#retrieveDataObject(java.util.Map)

retrieveKeySetFromMap

protected List<String> retrieveKeySetFromMap(List<List<String>> potentialKeySets,
                                             Map<String,String> parameters)

Iterates through the list of key sets looking for a set where the given map of parameters has all the key names and values are non-blank, first matched set is returned

Parameters:

potentialKeySets - - List of key sets to check for match

parameters - - map of parameter name/value pairs for matching key set

Returns:

List key set that was matched, or null if none were matched

getAlternateKeysForClass

protected List<List<String>> getAlternateKeysForClass(Class<?> clazz)

Invokes the module service to retrieve any alternate keys that have been defined for the given class

Parameters:

clazz - - class to find alternate keys for

Returns:

List> list of alternate key sets, or empty list if none are found

buildInquirableLink

public void buildInquirableLink(Object dataObject,
                                String propertyName,
                                Inquiry inquiry)

Description copied from interface: Inquirable

Invoked by the ViewHelperService to build a link to the inquiry

Note this is used primarily for custom Inquirable implementations to customize the inquiry class or parameters for an inquiry. Instead of building the full inquiry link, implementations can make a callback to org.kuali.rice.krad.uif.widget.Inquiry.buildInquiryLink(Object, String, Class, Map) given an inquiry class and parameters to build the link field.

Specified by:

buildInquirableLink in interface Inquirable

Parameters:

dataObject - - parent object for the inquiry property

propertyName - - name of the property the inquiry is being built for

inquiry - - instance of the inquiry widget being built for the property

See Also:

Inquirable.buildInquirableLink(java.lang.Object, java.lang.String, org.kuali.rice.krad.uif.widget.Inquiry)

setDataObjectClass

public void setDataObjectClass(Class<?> dataObjectClass)

Description copied from interface: Inquirable

Sets the class for the data object the inquirable should retrieve

Must be set before invoking any other operations on the Inquirable, including the retrieveDataObject method

Specified by:

setDataObjectClass in interface Inquirable

Parameters:

dataObjectClass - the class of the dataObject that this inquirable should retrieve

See Also:

Inquirable.setDataObjectClass(java.lang.Class)

getDataObjectClass

protected Class<?> getDataObjectClass()

Retrieves the data object class configured for this inquirable

Returns:

Class of configured data object, or null if data object class not configured

getDataObjectMetaDataService

protected DataObjectMetaDataService getDataObjectMetaDataService()

getKualiModuleService

protected KualiModuleService getKualiModuleService()

getDataDictionaryService

protected DataDictionaryService getDataDictionaryService()

Description copied from class: ViewHelperServiceImpl

Gets the data dictionary service

Overrides:

getDataDictionaryService in class ViewHelperServiceImpl

Returns:

DataDictionaryService data dictionary service

getDataObjectAuthorizationService

protected DataObjectAuthorizationService getDataObjectAuthorizationService()

getEncryptionService

protected EncryptionService getEncryptionService()

getBusinessObjectService

protected BusinessObjectService getBusinessObjectService()
