Method Details

find

@Nonnull
public <T extends IssueDataCallback> ServiceResult find(com.atlassian.jira.user.ApplicationUser user,
 com.atlassian.query.Query query,
 T callback)

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

findWithServiceOutcome

@Nonnull
public <T extends IssueDataCallback> ServiceResult findWithServiceOutcome(com.atlassian.jira.user.ApplicationUser user,
 com.atlassian.query.Query query,
 T callback)

Specified by:

findWithServiceOutcome in interface IssueDataService

findWithServiceOutcome

@Nonnull
public <T extends org.apache.lucene.search.Collector>
ServiceResult findWithServiceOutcome(com.atlassian.jira.user.ApplicationUser user,
