extends MamdaOrderBookComplexDelta
    MamdaOrderBookConcreteComplexDelta is a class that saves information about a complex order book delta. A complex delta involves multiple entries and/or price levels. For example, a modified order may involve a price change that means moving an entry from one price level to another. A complex delta is made up of several simple deltas, which can be iterated over by methods provided in the class.

      • getSrcTime

        public com.wombat.mama.MamaDateTime getSrcTime()
        Returns:
        Source time. Typically, the exchange generated feed time stamp. This is often the same as the "event time", because many feeds do not distinguish between the actual event time and when the exchange sent the message.

      • getSrcTimeFieldState

        public short getSrcTimeFieldState()
        Description copied from interface: MamdaBasicEvent
        return Source time Field State MODIFIED (2) value indicates the fied was updated in last tick NOT MODIFIED (1) value indicate that there was no change in the last tick NOT_INITIALISED (0) value indicates that the field has never been updated

      • setSrcTime

        public void setSrcTime​(com.wombat.mama.MamaDateTime srcTime)

      • getActivityTime

        public com.wombat.mama.MamaDateTime getActivityTime()
        Returns:
        Activity time. A feed handler generated time stamp representing when the data item was last updated.
