All Implemented Interfaces:

IssueDataService

@Service
public class IssueDataServiceImpl
extends AbstractLoggable
implements IssueDataService

Abstraction for a common usage pattern of querying a handful of issue fields from Lucene. Besides being convenient, this serves the purpose of keeping Lucene dependencies out of the code as much as possible.

find

Description copied from interface: IssueDataService

Execute the query, and for each issue in the result, extract the data as specified by the fields in the callback and send them over to the callback collector. For optimal memory usage, try streaming the data directly into the receiving data structure (like a REST template) instead of gathering it internally.

Specified by:

find in interface IssueDataService

callback - : This collects the field values of the issues matching the query

Returns:

any errors that happened during the search
