All Implemented Interfaces:

Direct Known Subclasses:

AutoOrderHistoryManager

public class LiveOrderHistoryManager
extends OrderHistoryManager
implements Lifecycle

Provides a historically-aware OrderHistoryManager implementation.

Instantiate this class with an origin date. The origin date establishes how far back to look for order history.

Note that there are significant performance and resource implications when using this class. Depending on historical order volume, this class may be required to process thousands or millions of reports. There are two ramifications of this:

• Make an effort to limit the number of instances of this class. Each instance in the same process has access to the same reports. The only reason to have more than one instance of this class is if more than one historical range is required. Even then, it is preferable to use a single instance with the oldest origin date.
• Use the most recent origin date feasible. Ideally, make this midnight of the current day, or whatever makes sense for the current trading session. Obviously, business requirements will dictate what the origin date is.

It may take a significant amount of time to start this object as it must process historical order history. Callers may choose to make this operation asynchronous. The object will report that it is running when the processing is complete.
