Class QuoteScenarioArray

java.lang.Object

com.opengamma.strata.market.observable.QuoteScenarioArray

All Implemented Interfaces:

ScenarioArray<Double>, Serializable, org.joda.beans.Bean, org.joda.beans.ImmutableBean

public final class QuoteScenarioArray
extends Object
implements ScenarioArray<Double>, org.joda.beans.ImmutableBean, Serializable

Container for values for an item of quoted market data in multiple scenarios.

This class is a more efficient alternative to storing quotes using MarketDataBox.ofScenarioValues or ScenarioValuesList.

It stores the quote values in a primitive double array which reduces memory footprint and avoids the overhead of boxing.

For maximum performance functions can access the array of quotes without boxing or copying via the quotes property. Functions should use a QuoteScenarioArrayId to request a QuotesArray from the market data container if they need direct access to the array of quotes.
