package com.pure.util;

import java.util.ArrayList;
import java.util.List;

import com.pure.domain.Image;

public class ActiveUploadFile {
	public static ActiveUploadFile self = null;

	private static List uploadFiles = new ArrayList();

	public static ActiveUploadFile getInstance() {
		if (self == null) {
			synchronized (ActiveUploadFile.class) {
				self = new ActiveUploadFile();
			}
		}
		return self;
	}

	public synchronized void addUploadFile(Image image) {
		uploadFiles.add(image);
	}

	public synchronized void removeUploadFile(Image uploadFile) {
		uploadFiles.remove(uploadFile);
	}
	
	public synchronized void removeUploadFile(int index) {
		uploadFiles.remove(index);
	}
	
	public synchronized void clear() {
		uploadFiles.clear();
	}
	
	
	
	public synchronized List getUploadFiles() {
		return uploadFiles;
