接口 AppendList<T>

所有超级接口：

Iterable<T>

所有已知实现类：

public interface AppendList<T>
extends Iterable<T>

Appendable list interface definition.

Two states are in this list. State AppendList.State.WRITE when instance created, then element can be append to tail. After all elements are appended, switch state to AppendList.State.READ. When state is AppendList.State.READ, data cannot be appended, only can be iterative.

Only support appending element to tail and iterative reading.

Such code as an example:

 AppendList<Data> dataList = new MemoryDiskList<Data>(60L, "c.txt");
 dataList.append(new Data(1, 1));
 dataList.append(new Data(2, 2));
 dataList.append(new Data(3, 3));
 dataList.append(new Data(4, 4));
 
 dataList.switchState();
 
 for(Data d: dataList) {
     System.out.println(d);
 }
