Class MongoComplexDataSource

Object

MongoComplexDataSource

All Implemented Interfaces:

CustomSourceDataStore

public final class MongoComplexDataSource
extends Object
implements CustomSourceDataStore

Class that builds an App-Schema iterator ready to be used with MongoDB. Data coming from MongoDB is assumed to be always normalized, when using MongoDB with App-Schema we cannot chain multiple collections together.

Method Detail

buildDataStore

public DataAccess<? extends FeatureType,? extends Feature> buildDataStore(SourceDataStore dataStoreConfig,
                                                                                AppSchemaDataAccessDTO appSchemaConfig)

Description copied from interface: CustomSourceDataStore

Builds a data store based on the provided App-Schema data store configuration. If the extension is NOT capable of building a data store based on the provided configuration NULL should be returned.

Specified by:

buildDataStore in interface CustomSourceDataStore

Parameters:

dataStoreConfig - App-Schema data store configuration

appSchemaConfig - App-Schema full configuration

Returns:

a data store build based on the provided configuration or NULL

configXmlDigesterDataSources

public void configXmlDigesterDataSources(Digester digester)

Description copied from interface: CustomSourceDataStore

Allows a data store to provide its own configuration to the XML parser \ digester for data sources.

Specified by:

configXmlDigesterDataSources in interface CustomSourceDataStore

Parameters:

digester - XML parser \ digester

configXmlDigesterAttributesMappings

public void configXmlDigesterAttributesMappings(Digester digester)

Description copied from interface: CustomSourceDataStore

Allows a data store to provide its own configuration to the XML parser \ digester for attributes mappings.

Specified by:

configXmlDigesterAttributesMappings in interface CustomSourceDataStore

Parameters:

digester - XML parser \ digester

buildIterator

public DataAccessMappingFeatureIterator buildIterator(AppSchemaDataAccess store,
                                                      FeatureTypeMapping featureTypeMapping,
                                                      Query query,
                                                      Transaction transaction)

Description copied from interface: CustomSourceDataStore

Allows a data store to build its own iterator that will be used by App-Schema core to retrieve the necessary attributes from the data store to build the mapped feature types. Stores can also if need change the current App-Schema query.

Specified by:

buildIterator in interface CustomSourceDataStore

Parameters:

store - the data store from where App-Schema will retrieve the necessary values

featureTypeMapping - the feature typ mapping that is being build by App-Schema core

query - the query that will \ should be submitted to the data store

transaction - the current transaction context

Returns:

a custom iterator or NULL

getSurrogatePropertyNames

public List<PropertyName> getSurrogatePropertyNames(List<PropertyName> requested,
                                                    FeatureTypeMapping featureTypeMapping)

Specified by:

getSurrogatePropertyNames in interface CustomSourceDataStore
