Method Detail

isLocked

public boolean isLocked()

isLockedBy

public boolean isLockedBy(long sessionId,
                          long threadId)

getFence

public long getFence()

Returns fencing token of the lock if it is currently hold by some endpoint. FencedLock.INVALID_FENCE otherwise

getLockCount

public int getLockCount()

getSessionId

public long getSessionId()

Returns the session id that currently holds the lock. Returns AbstractProxySessionManager.NO_SESSION_ID if not held

getThreadId

public long getThreadId()

Returns the thread id that holds the lock. If the lock is not held, return value is meaningless. When the lock is held, pair of is unique.

getFactoryId

public int getFactoryId()

Description copied from interface: IdentifiedDataSerializable

Returns DataSerializableFactory factory ID for this class.

Specified by:

getFactoryId in interface IdentifiedDataSerializable

Returns:

factory ID

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

Specified by:

getId in interface IdentifiedDataSerializable

Returns:

type ID

writeData

public void writeData(ObjectDataOutput out)
               throws IOException

Description copied from interface: DataSerializable
