extvisitor
Interface IExtVisitorCmd<R,I,P,H extends IExtVisitorHost<I,? super H>>

Type Parameters:

R - The type of the return value

I - The type of the index value

P - The type of the input parameters

H - The type of the host, restricted to being a subclass of IExtVisitorHost<I, ? super H>

All Superinterfaces:

java.io.Serializable

All Known Implementing Classes:

ADataPacketAlgoCmd, AStatusAlgoCmd

public interface IExtVisitorCmd<R,I,P,H extends IExtVisitorHost<I,? super H>>
extends java.io.Serializable

Interface that defines a command used by AExtVisitor that has specific types for its return value, R, its index value, I, its input parameters, P, and its host, H. The host is restricted to being a subclass of IExtVisitorHost who takes the same index value and who accepts a visitor that takes this same host type. An IExtVisitorCmd is associated with every recognized case of an AExtVisitor, including the default case.
Usage:

 
 new IExtVisitorCmd<MyReturn, MyIndex, MyParam, MyExtVisitorHost>(){
     public <T extends IExtVisitorHost<Integer, ? super MyExtVisitorHost>> MyReturn apply(MyIndex index, T host, MyParam... params) {...}
 }
