Example 71 with Hit

use of com.yahoo.search.result.Hit in project vespa by vespa-engine.

the class GroupingExecutor method fill.

            // which may be a fragile assumption. But currently we cannot do better because the difference
            // between explicit and implicit summary class in fill is erased by the Execution.
            // 
            // We reset the summary class here such that following fill calls will execute with the
            // summary class they specify
