Field Details

_duplicateScoringStrategy

protected AndDuplicateScoringStrategy<T extends IdentityBean<?>> _duplicateScoringStrategy

When comparing entities between two feeds to see if they are duplicates, we use the specified scoring strategy to score the amount of duplication between the two entities. Sub-classes can add rules to this scoring strategy specific to their entity type to guide duplication scoring.

public AbstractIdentifiableSingleEntityMergeStrategy(Class<T> entityType)

Method Details

pickBestDuplicateDetectionStrategy

protected EDuplicateDetectionStrategy pickBestDuplicateDetectionStrategy(GtfsMergeContext context)

Description copied from class: AbstractEntityMergeStrategy

Determines the best EDuplicateDetectionStrategy to use for merging entities from the current source feed into the merged output feed. Sub-classes are required to provide the most appropriate strategy for merging their particular entity type.

Specified by:

pickBestDuplicateDetectionStrategy in class AbstractEntityMergeStrategy

Parameters:

context -

Returns:

getIdentityDuplicate

protected IdentityBean<?> getIdentityDuplicate(GtfsMergeContext context,
 IdentityBean<?> entity)

Description copied from class: AbstractSingleEntityMergeStrategy

Use EDuplicateDetectionStrategy.IDENTITY based duplication-detection to find a duplicate in the output merged feed for the specified entity.

Specified by:

getIdentityDuplicate in class AbstractSingleEntityMergeStrategy<T extends IdentityBean<?>>

Parameters:

context -

entity -

Returns:

a duplicate entity with the specified id or null if none exists.

getFuzzyDuplicate

protected IdentityBean<?> getFuzzyDuplicate(GtfsMergeContext context,
 IdentityBean<?> entity)

Description copied from class: AbstractSingleEntityMergeStrategy

Use EDuplicateDetectionStrategy.FUZZY based duplication-detection to find a duplicate in the output merged feed for the specified entity.

Overrides:

getFuzzyDuplicate in class AbstractSingleEntityMergeStrategy<T extends IdentityBean<?>>

Parameters:

context -

entity -

Returns:

a duplicate entity that fuzzily matches the specified entity or null if none exists.

save

protected void save(GtfsMergeContext context,
 IdentityBean<?> entity)

Saves the specified entity to the merged output feed. If the raw id of the entity duplicates an existing entity in the output feed, its id will be renamed.

Overrides:

save in class AbstractSingleEntityMergeStrategy<T extends IdentityBean<?>>

Parameters:

context -

entity -

rename

protected void rename(GtfsMergeContext context,
 IdentityBean<?> entity)

Rename the id of the specified identity to avoid an raw GTFS identifier collision in the merged output feed.

Parameters:

context -

entity -
