public ConcurrentSegmentedStoredList(boolean supportFifoPerSegment,
 int inputNumOfSegments,
 boolean padded)

Method Details

size

public int size()

Description copied from interface: ICollection

Returns the amount of elements in the StoredList.

Specified by:

size in interface ICollection<T>

Overrides:

size in class ConcurrentStoredList<T>

Returns:

size of the StoredList

• ICollection.isEmpty()

getNumSegments

protected int getNumSegments()

get the number of segments in this SL

Overrides:

getNumSegments in class ConcurrentStoredList<T>

getSegment

protected StoredListChainSegment<T> getSegment(int seg)

Overrides:

getSegment in class ConcurrentStoredList<T>

incremenetAndGetSize

protected int incremenetAndGetSize()

Overrides:

incremenetAndGetSize in class ConcurrentStoredList<T>

incrementSize

protected void incrementSize()

Overrides:

decrementSize

protected void decrementSize()

Overrides:

invalidate

public boolean invalidate()

Description copied from class: ConcurrentStoredList

Sets an indication that this StoredList is invalid. if isEmpty() returns true, the indication is set; otherwise the indication remains false. Called by PersistentGC when scanning for empty StoredList that can be garbage collected.

Specified by:

invalidate in interface IStoredList<T>

Overrides:

invalidate in class ConcurrentStoredList<T>

Returns:

true if StoredList was set to invalid; false otherwise.

supportsInvalidation

protected boolean supportsInvalidation()

Overrides:

supportsInvalidation in class ConcurrentStoredList<T>
