Modifier and Type	Method and Description
protected Collection<?>	executeAttributeQueryCriteria(AttributeQuery attributeQuery, Map<String,String> queryParameters, Map<String,String> additionalCriteria, List<String> wildcardAsLiteralPropertyNames) Prepares a query using the configured data object, parameters, and criteria, then executes the query and returns the result Collection

Method Detail

performFieldSuggestQuery

public AttributeQueryResult performFieldSuggestQuery(ViewPostMetadata viewPostMetadata,
                                            String fieldId,
                                            String fieldTerm,
                                            Map<String,String> queryParameters)

Executes the AttributeQuery associated with the Suggest widget within the field given by the Id. The given Map of key/value pairs are used to populate the criteria part of the attribute query or as arguments to the query method. The fieldTerm parameter gives the current value of the field that should be matched on. The query is expected to return a list of values to suggest

Specified by:

performFieldSuggestQuery in interface AttributeQueryService

Parameters:

viewPostMetadata - - post metadata related to the field

fieldId - - id for the attribute field to perform the query for

fieldTerm - - the partial value of the query field to match

queryParameters - - map of key/value pairs that are parameters to the query

Returns:

AttributeQueryResult instance populated with the List data field of result data

retrievePropertiesOnResults

protected void retrievePropertiesOnResults(AttributeQueryResult queryResult,
                               Collection<?> results,
                               Suggest.SuggestPostData suggestPostData)

Instead of returning the full object this method fills in queryResult with data that contain the properties of each result object, as configured through the fieldSuggest, from the set of results.

Parameters:

queryResult - the queryResult to fill in

results - the set of original results

suggestPostData - post data for the suggest widget

performFieldQuery

public AttributeQueryResult performFieldQuery(ViewPostMetadata viewPostMetadata,
                                     String fieldId,
                                     Map<String,String> queryParameters)

Executes the AttributeQuery associated with the field given by the id. The given Map of key/value pairs are used to populate the criteria part of the attribute query or as arguments to the query method. The query is expected to return a Map of field name/value pairs (unlike the suggest query which just returns values for one field)

Specified by:

performFieldQuery in interface AttributeQueryService

Parameters:

viewPostMetadata - - post metadata related to the field

fieldId - - id for the attribute field to perform the query for

queryParameters - - map of key/value pairs that are parameters to the query

Returns:

AttributeQueryResult instance populated with the Map of result field data

executeAttributeQueryMethod

protected Object executeAttributeQueryMethod(AttributeQuery attributeQuery,
                                 Map<String,String> queryParameters,
                                 boolean isSuggestQuery,
                                 String queryTerm)

Prepares the method configured on the attribute query then performs the method invocation

Parameters:

attributeQuery - attribute query instance to execute

queryParameters - map of query parameters that provide values for the method arguments

isSuggestQuery - indicates whether the query is for forming suggest options

queryTerm - if being called for a suggest, the term for the query field

Returns:

type depends on method being invoked, could be AttributeQueryResult in which case the method has prepared the return result, or an Object that needs to be parsed for the result

executeAttributeQueryCriteria

protected Collection<?> executeAttributeQueryCriteria(AttributeQuery attributeQuery,
                                          Map<String,String> queryParameters,
                                          Map<String,String> additionalCriteria,
                                          List<String> wildcardAsLiteralPropertyNames)

Prepares a query using the configured data object, parameters, and criteria, then executes the query and returns the result Collection

Parameters:

attributeQuery - attribute query instance to perform query for

queryParameters - map of parameters that will be used in the query criteria

additionalCriteria - map of additional name/value pairs to add to the critiera

wildcardAsLiteralPropertyNames - - List of property names with wildcards disabled

Returns:

results of query
