```
public class OrderBase
extends MarketEvent
implements IndexedEvent<String>
```
Base class for common fields of Order, AnalyticOrder, OtcMarketsOrder and SpreadOrder events. Order events represent a snapshot for a full available market depth for a symbol. The collection of order events of a symbol represents the most recent information that is available about orders on the market at any given moment of time.
Order event represents market depth for a specific symbol.
AnalyticOrder event represents market depth for a specific symbol extended with an analytic information, for example, whether particular order represent an iceberg or not.
OtcMarketsOrder event represents market depth for a specific symbol traded on the OTC Markets. The event is extended with the additional OTC Markets quote data, such as Quote Access Payment (QAP) value, Quote Price Type, Open/Closed status, and Unsolicited state indication, when applicable.
SpreadOrder event represents market depth for all spreads on a given underlying symbol.
Order events arrive from multiple sources for the same market symbol and are distinguished by their index. Index is a unique per symbol identifier of the event. It is unique across all the sources of depth information for the symbol. The event with sizeAsDouble either 0 or NaN is a signal to remove previously received order for the corresponding index. The method hasSize is a convenient method to test for size presence.
Event flags, transactions and snapshots
Some order event sources provide a consistent view of the price-level or detailed order book. Their updates may incorporate multiple changes to price levels or to individual orders that have to be processed at the same time. The corresponding information is carried in eventFlags property. The logic behind this property is detailed in IndexedEvent class documentation.
The event source identifier for an order is a part of the unique event index. It occupies highest bits of the index (index is not-negative). The lowest bits of index contain source-specific event index which is always zero in an event that is marked with IndexedEvent.SNAPSHOT_END bit in eventFlags.
Note that for an order with IndexedEvent.REMOVE_EVENT bit in eventFlags it is always the case that sizeAsDouble is either 0 or NaN, so no additional logic to process this bit is required for orders. Transactions and snapshots may include orders with sizeAsDouble of 0. The filtering that distinguishes those events as removals of orders shall be performed after all transactions and snapshot processing.
Some aggregated feeds (like CME market depth) are mapped into two distinct source ids (one for buy orders and one for sell orders), but updates and transactions may span both. It is important to keep a separate track of transactional state for each source id, but, at the same time, when DXFeedEventListener.eventsReceived method is called for a list of events, the order book shall be considered complete and consistent only when all events from the given list are processed.
OrderBookModel class contains all the appropriate logic to deal with transactions and snapshots for Order events. The client-visible changes to the model are reported only when the snapshot for the specific source id is received completely and when there is no ongoing transaction for the specific source id. It relies on the code of AbstractIndexedEventModel to handle this logic. Use the source code of AbstractIndexedEventModel for clarification on transactions and snapshot logic.
