Constructor Summary

protected

SegmentedHashMap.EntryActionAdapter()

Method Summary

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.
Object	invokeNotFound(Object oKey, Object oContext, SegmentedHashMap.Entry[] aeBucket, int nBucket) Invoke some action, holding the segment lock, when no matching Entry is found.
boolean	isComplete(Object oContext) Return true iff further key evaluations for the given context are known to be unnecessary.

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
