Interface IndexingUriFinder

All Known Implementing Classes:

AdditionalURIsForClassGroupChanges, AdditionalURIsForDataProperties, AdditionalURIsForObjectProperties, AdditionalURIsForTypeStatements, SelectQueryUriFinder, URIsForClassGroupChange

public interface IndexingUriFinder

Interface to use with IndexBuilder to find more URIs to index given a changed statement. The statement may have been added or removed from the model. Implementing classes must be threadsafe, as multiple threads are used to complete the task. The life-cycle is as follows: startIndexing(), 0 or more calls to findAdditionalURIsToIndex(), endIndexing(). Repeat as desired.

Method Summary

Modifier and Type	Method	Description
void	endIndexing()	Indicates that the collection of statements being processed is complete.
List<String>	findAdditionalURIsToIndex(org.apache.jena.rdf.model.Statement stmt)	For the domain that is the responsibility of the given implementation, calculate the URIs that need to be updated in the search index.
void	startIndexing()	Indicates that a new collection of statements is about to be processed.

Method Detail

findAdditionalURIsToIndex

List<String> findAdditionalURIsToIndex(org.apache.jena.rdf.model.Statement stmt)

For the domain that is the responsibility of the given implementation, calculate the URIs that need to be updated in the search index. The URIs in the list will be updated by the IndexBuilder, which will handle URIs of new individuals, URIs of individuals that have changes, and URIs of individuals that have been removed from the model.

Returns:

List of URIs. Never return null.

startIndexing

void startIndexing()

Indicates that a new collection of statements is about to be processed.

endIndexing

void endIndexing()

Indicates that the collection of statements being processed is complete.
