Class Value

wanActiveActive.Value

All Implemented Interfaces:

com.gemstone.gemfire.pdx.PdxSerializable

public class Value
extends Object
implements com.gemstone.gemfire.pdx.PdxSerializable

Value is the class of objects stored in the cache by this example application. It contains an integer field which the example increments on every update, a string field that shows the origin of the update and a history list of the changes that have been made to it.

Value implements the GemFire PdxSerializable interface for highest serialization performance. PdxSerializable also allows cache servers to view and manipulate the object without having reference its class in their classpath.
