  • Field Details

    • m_lock

      protected final ReadWriteLock m_lock
      The read/write lock for concurrency control.

    • m_lockShared

      protected final Lock m_lockShared
      The shared lock for performing read operations.

      Note: This field is null if read-only operations are not supposed to be protected, i.e. if the "strict" option is not used.

    • m_lockExclusive

      protected final Lock m_lockExclusive
      The exclusive lock for performing read/write operations.

  • Constructor Details

    • ConcurrentWrapperEntry

      public ConcurrentWrapperEntry(Map.Entry<K,V> entry)
      Create an ConcurrentWrapperEntry which delegates to the specified Map Entry.
      Parameters:
      entry - the Map Entry to delegate all calls to

    • ConcurrentWrapperEntry

      protected ConcurrentWrapperEntry(Map.Entry<K,V> entry, ReadWriteLock lock)
      Create an ConcurrentWrapperEntry which delegates to the specified Map Entry.
      Parameters:
      entry - the Map Entry to delegate all calls to
      lock - a read/write lock for concurrency management

    • ConcurrentWrapperEntry

      protected ConcurrentWrapperEntry(Map.Entry<K,V> entry, ReadWriteLock lock, boolean fStrict)
      Create an ConcurrentWrapperEntry which delegates to the specified Map Entry.
      Parameters:
      entry - the Map Entry to delegate all calls to
      lock - a read/write lock for concurrency management
      fStrict - pass true to protect all Entry methods; false to protect only the setValue() method
