Method Detail

setRecordState

public void setRecordState(RecordState pRecordState)

Sets the record state representing the current request.

wrapConfig

protected RecordDetailsConfig wrapConfig(ContentItem pContentItem)

Description copied from class: NavigationCartridgeHandler

Wraps the input ContentItem as a typed config object. It is not expected that subclasses will mutate the input ContentItem, beyond passing it into their typed configuration class as a constructor argument.

Specified by:

wrapConfig in class NavigationCartridgeHandler<RecordDetailsConfig,RecordDetails>

Parameters:

pContentItem - the configuration for this cartridge handler. This will either be the fully initialized configuration object, if a ContentItemInitializer has been set, or it will simply be the instance configuration.

Returns:

an instance of ConfigType which wraps the input ContentItem.

See Also:

NavigationCartridgeHandler.initialize(ContentItem), NavigationCartridgeHandler.setContentItemInitializer(ContentItemInitializer)

preprocess

public void preprocess(RecordDetailsConfig cartridgeConfig)
                throws CartridgeHandlerException

Creates a record details MDEX query.

Overrides:

preprocess in class NavigationCartridgeHandler<RecordDetailsConfig,RecordDetails>

Throws:

CartridgeHandlerException

process

public RecordDetails process(RecordDetailsConfig cartridgeConfig)
                      throws CartridgeHandlerException

Creates a RecordDetails model object.

Overrides:

process in class NavigationCartridgeHandler<RecordDetailsConfig,RecordDetails>

Throws:

CartridgeHandlerException

getFilterState

protected FilterState getFilterState(NavigationState navigationState)

Retrieves the filter state to use when making record detail queries. This implementation always returns an empty filter state, but can be overridden by subclasses if different behavior is desired.

combineFieldNames

protected List<String> combineFieldNames(NavigationState navigationState,
                                         com.endeca.infront.cartridge.FieldNamesConfig config)
                                  throws CartridgeHandlerException

Updates the list of string for retaining representative record properties.

Returns:

the combined field names from representative record field names, sub-record field names and potentially DGraph.WhyRank and DGraph.WhyMatch if whymatch and whyrank are turned on respectively.

Throws:

CartridgeHandlerException

getTotalNumRecs

protected static long getTotalNumRecs(com.endeca.navigation.ENEQueryResults results)

createRecords

protected List<Record> createRecords(com.endeca.navigation.ENEQueryResults results,
                                     NavigationState navigationState,
                                     com.endeca.infront.cartridge.FieldNamesConfig config)

Convert the records found in the given query to Record form.

Parameters:

results - result of MDEX query.

navigationState - base navigation state for record details links. If null, record details links are omitted.

retainFields

protected void retainFields(Map<String,Attribute> attributeMap,
                            com.endeca.infront.cartridge.FieldNamesConfig config,
                            boolean aggregationEnabled)

Helper method for retaining properties. Assumes getFieldNames() does not return null

Parameters:

attributeMap - A list of attributes to maintain on the records.

config - Cartridge Configuration used to determine which attributes to include.

aggregationEnabled - TRUE if aggregation is enabled on the request.
