Class DefaultC4CAggregatingCollector

java.lang.Object

de.hybris.platform.c4ccustomer.deltadetection.impl.DefaultC4CAggregatingCollector

All Implemented Interfaces:

ChangesCollector, C4CAggregatingCollector

public class DefaultC4CAggregatingCollector
extends java.lang.Object
implements C4CAggregatingCollector

Collector that grabs changes of CustomerModel models and fetches related AddressModel and vice versa. So, as a result there is a set of changed customers with all addresses belonging to each. 'Changed' here stands for 'something has changed in customer fields or any of the addresses related'.

Deleted customers are skipped, because C4C does not implement customer removal yet.

Constructor Detail

DefaultC4CAggregatingCollector

public DefaultC4CAggregatingCollector()

Method Detail

collect

public boolean collect(ItemChangeDTO itemChangeDTO)

Description copied from interface: ChangesCollector

Collects the given change in a specified way.

Specified by:

collect in interface ChangesCollector

Parameters:

itemChangeDTO - change to be collected

Returns:

true, if the collecting process should continue, false otherwise

finish

public void finish()

This implementation does not finalizes the subsequent collectors. It has to be done manually outside of the class scope.

The only reason is the collector is used multiple times (for customers and for addresses), so finalizing batching collectors in between would produce smaller chunks.

Specified by:

finish in interface ChangesCollector

setCustomerConfigurationId

public void setCustomerConfigurationId(@Nonnull
                                       java.lang.String id)

Specified by:

setCustomerConfigurationId in interface C4CAggregatingCollector

Parameters:

id - stream configuration id for customers.

setAddressConfigurationId

public void setAddressConfigurationId(@Nonnull
                                      java.lang.String id)

Specified by:

setAddressConfigurationId in interface C4CAggregatingCollector

Parameters:

id - stream configuration id for addresses.

setFlexibleSearchService

public void setFlexibleSearchService(FlexibleSearchService flexibleSearchService)

setChangeDetectionService

public void setChangeDetectionService(ChangeDetectionService changeDetectionService)

setTypeService

public void setTypeService(TypeService typeService)

fetchAllDependenciesOf

protected void fetchAllDependenciesOf(@Nonnull
                                      ItemChangeDTO itemChangeDTO)
