public java.lang.Object 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.
Specified by:
invokeFound in interface SegmentedHashMap.EntryAction
Parameters:
oKey - the key to which the action is applied
oContext - opaque context specific to the action
aeBucket - the bucket array
nBucket - the index into the bucket array
entryPrev - the Entry object immediately preceding the Entry that was found, or null
entryCur - the Entry object that was found
Returns:
an opaque result value

invokeNotFound

                                       java.lang.Object oContext,
                                       SegmentedHashMap.Entry[] aeBucket,
                                       int nBucket)
Invoke some action, holding the segment lock, when no matching Entry is found.
Specified by:
invokeNotFound in interface SegmentedHashMap.EntryAction
Parameters:
oKey - the key to which the action is applied
oContext - opaque context specific to the action
aeBucket - the bucket array
nBucket - the index into the bucket array
Returns:
an opaque result value

isComplete

public boolean isComplete(java.lang.Object oContext)
Return true iff further key evaluations for the given context are known to be unnecessary.
Specified by:
isComplete in interface SegmentedHashMap.IterableEntryAction
Parameters:
oContext - the action context
