List of lockAttributes() Examples

Examples of lockAttributes()

org.apache.derby.iapi.services.locks.Lockable.lockAttributes()
If this lockable object wants to participate in a diagnostic virtual lock table, then put any relevant attributes of this lock into the attributes list (the attribute must be an immutable object). The list of attributes of interest to the virtual lock table can be found in VirtualLockTable. The toString method will be called by the VirtualTable on the attribute value for display.
@param flag use the bits in this int to decide if the user isinterested in this kind of lockable object. The bits are defined in VirtualLockTable. For instance, the user may only ask for TABLE_AND_ROWLOCK and if this is not a table or row lock, then don't participate. @param attributes if this decides to participate, put all relevantattributes into the Hashtable. The complete list of interesting attributes is listed in VirtualLockTable. The following attributes must be present for all participating lockables: VirtualLockTable.LOCKNAME, VirtualLockTable.LOCKTYPE, either VirtualLockTable.CONTAINERID or VirtualLockTable.CONGLOMID,
MT - this routine must be MP safe, caller will not be single threading the lock manager.
@return true if this object has diagnostic information to add to thevirtual lock table. If this object either does not want to participate in the diagnostic virtual lock table or none of the attributes requested are attributes of this lock, returns false. @see VirtualLockTable
