protected class SegmentedHashMap.RemoveAction
- extends SegmentedHashMap.EntryActionAdapter
Action support for remove(). The action performs a locked remove, and is expected to run while holding the segment-lock for the specified key. <p/> The context object for a RemoveAction is unused. <p/> The result of invoking a RemoveAction is the previous value associated with the specified key, or NO_VALUE if no mapping for the key exists in the map. Note that a synthetic Entry does not represent a key-value mapping, so NO_VALUE is returned if a matching synthetic Entry is found.
