java.lang.Object

com.pervasive.datarush.graphs.EngineConfig.Sort

Enclosing class:

EngineConfig

public static final class EngineConfig.Sort
extends Object

Settings in this object determine default tuning for the Sort operator. This applies to any sort operators, either those that are implicitly injected by the framework or those that are explicitly added to the graph. Note that these merely determine the default values; settings may be explicitly overridden by adding an explicit Sort operator.
