Method Detail

isLocal

public boolean isLocal()

Specified by:

isLocal in interface GridCacheEntryEx

Overrides:

isLocal in class GridCacheMapEntry

Returns:

True if local.

tmLock

public boolean tmLock(IgniteInternalTx tx,
                      long timeout,
                      @Nullable
                      @Nullable GridCacheVersion serOrder,
                      GridCacheVersion serReadVer,
                      boolean read)

serReadVer - Optional read entry version for optimistic serializable transaction.

read - Read lock flag.

Returns:

True if lock was acquired, false otherwise.

Throws:

GridCacheEntryRemovedException - If this entry is obsolete.

recheck

public boolean recheck(GridCacheVersion ver)

Rechecks if lock should be reassigned.

Parameters:

ver - Thread chain version.

Returns:

True if thread chain processing must be stopped.

protected void checkThreadChain(GridCacheMvccCandidate owner)

Specified by:

checkThreadChain in class GridCacheMapEntry

Parameters:

owner - Starting candidate in the chain.

removeLock

public boolean removeLock(GridCacheVersion ver)
                   throws GridCacheEntryRemovedException

Parameters:

ver - Removes lock.

Returns:

True If lock has been removed.

Throws:

GridCacheEntryRemovedException - If this entry has been removed from cache.

toString

public String toString()

Overrides:

toString in class GridCacheMapEntry
