Method Detail

invokeFound

public Object invokeFound(Object oKey,
                          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

public Object invokeNotFound(Object oKey,
                             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(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

Returns:

true iff further evaluations are unnecessary
