java.lang.Object

listFW.MTList

All Implemented Interfaces:

IList

public class MTList
extends java.lang.Object
implements IList

Represents the unique empty list using the singleton pattern. Provides concrete code for the execute method: simply calls the emptyCase method of the IListAlgo parameter, passing to this method itself as the host and the given input Object as the input.

Method Detail

execute

public final java.lang.Object execute(IListAlgo algo,
                       java.lang.Object... inp)

Calls the empty case of the algorithm algo, passing to it itself as the host parameter and the given input inp as the input parameter. This method is marked as final to prevent all subclasses from overriding it. Finalizing a method also allows the compiler to generate more efficient calling code.

Specified by:

execute in interface IList

Parameters:

algo - an extrinsic operation (algorithm) on this IList.

inp - a variable number of input parameters needed by algo to perform the computation.

Returns:

an Object representing the output of the computation.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
