com.tangosol.util.SegmentedHashMap.ContainsValueAction
protected static class SegmentedHashMap.ContainsValueAction
Action support for containsValue(). The action performs a lookup by value and is not required to run while holding any segment-locks. <p/> The context object for a ContainsValueAction is an opaque context created by instantiateContext. <p/> The result of invoking a ContainsValueAction is Boolean.TRUE if the value is found in the map or Boolean.FALSE if the value is not found in the map.
