com.tangosol.util.SegmentedHashMap.EntryActionAdapter
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.
The context object for a ContainsValueAction is an opaque context created by instantiateContext.
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.

invokeFound(java.lang.Object oKey, java.lang.Object oContext, SegmentedHashMap.Entry[] aeBucket, int nBucket, SegmentedHashMap.Entry entryPrev, SegmentedHashMap.Entry entryCur) Invoke some action, holding the segment lock, when a matching Entry is found. |
boolean |
isComplete(java.lang.Object oContext) Return true iff further key evaluations for the given context are known to be unnecessary. |
boolean |
isFound(java.lang.Object oContext) Return true iff the value was found |
