    • isReplaceableBy

      public abstract boolean isReplaceableBy(long txTimestamp, Object newVersion, Comparator versionComparator)
      Determine if the current entry can be overridden with a value corresponding to the given new version and the transaction timestamp.
      Parameters:
      txTimestamp - the timestamp of the transaction
      newVersion - the new version for the replacement value
      versionComparator - the comparator to use for the version
      Returns:
      true if the value can be replaced, false otherwise

    • getValue

      public abstract Object getValue()
      Returns:
      the value contained, or null if none exists

    • getValue

      public abstract Object getValue(long txTimestamp)
      Parameters:
      txTimestamp - the timestamp of the transaction
      Returns:
      the value contained if it was created before the transaction timestamp or null

    • getVersion

      public Object getVersion()
      Returns:
      the version representing the value of null if the entry is not versioned

    • matches

      public abstract boolean matches(ExpiryMarker lock)
      Returns:
      true if the Expirable matches using the specified lock, false otherwise

    • markForExpiration

      public abstract ExpiryMarker markForExpiration(long timeout, String nextMarkerId)
      Mark the entry for expiration with the given timeout and marker id.

      For every invocation a corresponding call to ExpiryMarker.expire(long) should be made, provided that the returned marker matches(ExpiryMarker)

      Parameters:
      timeout - the timestamp in which the lock times out
      nextMarkerId - the next lock id to use if creating a new lock
      Returns:
      the newly created marker, or the current marker with a higher multiplicity
