Constructor Detail

XtnData

public XtnData(XtnEntry xtnEntry)

Method Detail

isLockedEntry

public boolean isLockedEntry(IEntryCacheInfo pEntry)

signalRewrittenEntry

public void signalRewrittenEntry(String uid)

given a uid, signal the entry as rewritten under the xtn

Parameters:

uid - - uid of entry to signal

isReWrittenEntry

public boolean isReWrittenEntry(String uid)

check weather an entry is rewritten under xtn

Parameters:

uid - - uid of entry to check

Returns:

true is entry with this uid is rewritten under xtn

removeRewrittenEntryIndication

public void removeRewrittenEntryIndication(String uid)

remove reWritten entry indication if exists

Parameters:

uid - -uid of entry

getUnderXtnEntries

public IStoredList<IEntryCacheInfo> getUnderXtnEntries(int selectType)

get the relevant entries under the xtn according to selected type

Parameters:

selectType - - selected type of entries under the xtn, from com.j_spaces.core.sadapter.SelctType

Returns:

IStoredList

anyFifoEntries

public boolean anyFifoEntries()

getXtn

public ServerTransaction getXtn()

Returns:

the xtn

getXtnEntry

public XtnEntry getXtnEntry()

Returns:

the xtn entry

addLockedEntry

public void addLockedEntry(IEntryCacheInfo pEntry,
                           OperationID operationID,
                           boolean fifo)

updateLock

public void updateLock(IEntryCacheInfo pEntry,
                       OperationID operationID,
                       boolean isReadOperation,
                       boolean fifo)

When user operation under transaction is upgraded from read to update/take, the order of entry should be changed to the most recent, so that the changes in prepare come in the right order. For example: read object A read object B take object B take object A will cause a prepare of: B,A instead of A,B. Repeatable read doesn't cause the upgrade since it is not reflected in prepare.

getOperationID
