Package org.springframework.data.gemfire.function

Class PojoFunctionWrapper

java.lang.Object

org.springframework.data.gemfire.function.PojoFunctionWrapper

All Implemented Interfaces:

Serializable, Function, Identifiable

public class PojoFunctionWrapper
extends Object
implements Function

Invokes a given POJO Method as a (remote) GemFire/Geode Function. If the POJO has a constructor that takes a Map, and the Function context is a Region, the Region will be injected. The delegate class name, the method name, and Method arguments are part of the Function invocation, therefore all arguments must be Serializable or an alternate serialization strategy must be used. The delegate Class must be on the class path of the remote cache(s).

Since:

1.2.0
