Class EqStruct

java.lang.Object

objects.EqStruct

All Implemented Interfaces:

com.gemstone.gemfire.DataSerializable, Serializable, objects.ConfigurableObject, TimestampedObject, UpdatableObject

public class EqStruct
extends Object
implements objects.ConfigurableObject, com.gemstone.gemfire.DataSerializable, TimestampedObject, UpdatableObject

The EqStruct is based on the UseCase12 Benchmark and provides us with a flat object graph with many fields that implements the DataSerializable interface and avoids the overhead associated with reflection during seralization.

Since:

4.1
