com.almworks.jira.structure.api.forest.raw.ForestParentChildrenListClosure<T>

All Implemented Interfaces:

ForestParentChildrenClosure<T,List<T>>

public abstract class ForestParentChildrenListClosure<T>
extends Object
implements ForestParentChildrenClosure<T,List<T>>

This is a utility implementation of ForestParentChildrenClosure that collects the results of processing sub-rows into a list. This list is then passed to ForestParentChildrenClosure.visitRow(com.almworks.jira.structure.api.forest.raw.ForestIterationControl, long, com.almworks.integers.LongList, C) as a children carry.

Note that the list passed to visitRow() is in the reverse order, that is, the first result is for the last child row.
