Package org.jgroups.blocks

Class MethodCall

java.lang.Object

org.jgroups.blocks.MethodCall

All Implemented Interfaces:

Constructable<MethodCall>, Streamable

Direct Known Subclasses:

PerfUtil.CustomCall, PerfUtil.GetCall, PerfUtil.PutCall

public class MethodCall
extends Object
implements Streamable, Constructable<MethodCall>

A method call is the JGroups representation of a remote method. It includes the name of the method (case sensitive) and a list of arguments. A method call is serializable and can be passed over the wire.
