Method Detail

performSearch

public Collection<?> performSearch(LookupForm form,
                                   Map<String,String> searchCriteria,
                                   boolean bounded)

Invoked to carry out the lookup search based on the given map of key/value search values.

Specified by:

performSearch in interface Lookupable

Parameters:

form - lookup form instance containing the lookup data

searchCriteria - map of criteria currently set

bounded - indicates whether the results should be limited (if necessary) to the max search result limit configured

Returns:

the list of result objects, possibly bounded with CollectionIncomplete

executeSearch

protected Collection<?> executeSearch(Map<String,String> adjustedSearchCriteria,
                                      List<String> wildcardAsLiteralSearchCriteria,
                                      boolean bounded,
                                      Integer searchResultsLimit)

Invoked to execute the search with the given criteria and restrictions.

Parameters:

adjustedSearchCriteria - map of criteria that has been adjusted (encyrption, ebos, etc)

wildcardAsLiteralSearchCriteria - map of criteria to treat as literals (wildcards disabled)

bounded - indicates whether the search should be bounded

searchResultsLimit - for bounded searches, the result limit

Returns:

Collection collection of data object instances from the search results

processSearchCriteria

protected Map<String,String> processSearchCriteria(LookupForm lookupForm,
                                                   Map<String,String> searchCriteria)

Filters the search criteria to be used with the lookup.

Processing entails primarily of the removal of filtered and unused/blank search criteria. Encrypted field values are decrypted, and date range fields are combined into a single criteria entry.

In special cases additional non-valid criteria may be included. E.g. with the KIM User Control as a criteria the principal name may be passed so that it is displayed on the control. The filtering removes these values based on the viewPostMetadata. When calling the search directly (methodToCall=search) the viewPostMetadata is not set before filtering therefore non-valid criteria are not supported in these cases.

Parameters:

lookupForm - lookup form instance containing the lookup data

searchCriteria - map of criteria to process

Returns:

map of processed criteria

identifyWildcardDisabledFields

protected List<String> identifyWildcardDisabledFields(LookupForm lookupForm,

searchCriteria - Map of property names and values to use as search parameters

Returns:

List of property names which have wildcard characters disabled

protected boolean validateSearchParameters(LookupForm form,
                                           Map<String,String> searchCriteria)

Invoked to perform validation on the search criteria before the search is performed.

Check required criteria have a value Check that criteria data type supports wildcards/operators Check that wildcards/operators are not used on a secure criteria Display info message when wildcards/operators are disabled Throw exception when invalid criteria are specified

Parameters:

generateLookupResultsMessages

protected void generateLookupResultsMessages(Map<String,String> searchCriteria,

Messages are generated for the number of results, if the results exceed the result limit, and if the search was done using the primary keys for the data object.

Parameters:

searchCriteria - map of search criteria that was used for the search

searchResults - list of result data objects from the search

sortSearchResults

protected void sortSearchResults(LookupForm form,
                                 List<?> searchResults)

Sorts the given list of search results based on the lookup view's configured sort attributes.

First if the posted view exists we grab the sort attributes from it. This will take into account expressions that might have been configured on the sort attributes. If the posted view does not exist (because we did a search from a get request or form session storage is off), we get the sort attributes from the view that we will be rendered (and was initialized before controller call). However, expressions will not be evaluated yet, thus if expressions were configured we don't know the results and can not sort the list

Parameters:

form - lookup form instance containing view information

searchResults - list of search results to sort

getSearchResults

protected Collection<?> getSearchResults(Map<String,String> searchCriteria,
                                         List<String> wildcardAsLiteralSearchCriteria,
                                         boolean unbounded,
                                         Integer searchResultsLimit)

Performs a normal search using the LookupService.

Parameters:

searchCriteria - map of criteria currently set

wildcardAsLiteralSearchCriteria - list of property names which have wildcard characters disabled

unbounded - indicates whether the complete result should be returned. When set to false the result is limited (if necessary) to the max search result limit configured.

searchResultsLimit - result set limit

Returns:

list of result objects, possibly bounded

getSearchResultsForEBO

protected List<?> getSearchResultsForEBO(Map<String,String> searchCriteria,
                                         boolean unbounded)

Performs a search against an ExternalizableBusinessObject by invoking the module service

Parameters:

searchCriteria - map of criteria currently set

unbounded - indicates whether the complete result should be returned. When set to false the result is limited (if necessary) to the max search result limit configured.

Returns:

list of result objects, possibly bounded

                                       Map<String,String> lookupCriteria)

Invoked when the clear action is requested to reset the search fields to their initial default values.

Specified by:

performClear in interface Lookupable

Parameters:

buildReturnUrlForResult

Invoked to build the return URL for a result row.

Based on the line contained in the field context, the URL for returning the role is constructed and set as the href for the link. If a return link cannot be constructed the link should be set to not render

Specified by:

buildReturnUrlForResult in interface Lookupable

Parameters:

returnLink - link that will be used to render the return URL

model - lookup form containing the data

isResultReturnable

protected boolean isResultReturnable(Object dataObject)

Determines whether a given data object that's returned as one of the lookup's results is considered returnable, which means that for single-value lookups, a "return value" link may be rendered, and for multiple value lookups, a checkbox is rendered.

Note that this can be part of an authorization mechanism, but not the complete authorization mechanism. The component that invoked the lookup/ lookup caller (e.g. document, nesting lookup, etc.) needs to check that the object that was passed to it was returnable as well because there are ways around this method (e.g. crafting a custom return URL).

Parameters:

dataObject - an object from the search result set

Returns:

true if the row is returnable and false if it is not

getReturnUrl

Builds the URL for returning the given data object result row.

Note return URL will only be built if a return location is specified on the lookup form

Parameters:

lookupView - lookup view instance containing lookup configuration

lookupForm - lookup form instance containing the data

dataObject - data object instance for the current line and for which the return URL is being built

Returns:

String return URL or blank if URL cannot be built

Builds up a Properties object that will be used to provide the request parameters for the return URL link

Parameters:

Returns:

Properties instance containing request parameters for return URL
