protected class SegmentedHashMap.GetEntryAction extends Object implements SegmentedHashMap.EntryAction
The context object for a GetEntryAction is either Boolean.TRUE or Boolean.FALSE indicating whether or not to return synthetic entries.
The result of invoking a GetEntryAction is the (possibly synthetic) Entry corresponding to a given key, null if no matching Entry is found, or NO_VALUE indicating that a concurrent resize occurred, and the operation must be repeated.
