1、ObservableList 基础 List 类型测试
cs
using System;
using System.Collections.Specialized;
using ObservableCollections;
using UnityEngine;
namespace Aladdin.Standard.Observable.Collections.List
{
public class ObservableListTest : MonoBehaviour
{
protected readonly ObservableList<int> observableList = new ObservableList<int>();
public void Start()
{
ISynchronizedView<int, string> observableListSynchronizedView = this.observableList.CreateView((value) => $"这是测试数据: {value}");
observableListSynchronizedView.ViewChanged += this.ObservableListSynchronizedViewViewChanged;
this.observableList.Add(1);
this.observableList.Add(2);
this.observableList.Add(3);
this.observableList.AddRange(new[] { 4, 5, 6 });
this.observableList[4] = 8;
this.observableList.RemoveAt(0);
this.observableList.Move(2, 0);
foreach (int value in this.observableList)
{
Debug.LogError($"{value}");
}
foreach (string value in observableListSynchronizedView)
{
Debug.LogError($"{value}");
}
this.observableList.Sort();
this.observableList.Reverse();
this.observableList.Clear();
observableListSynchronizedView.Dispose();
}
internal void ObservableListSynchronizedViewViewChanged(in SynchronizedViewChangedEventArgs<int, string> eventArgs)
{
switch (eventArgs.Action)
{
case NotifyCollectionChangedAction.Add:
Debug.LogError($"添加数据：{eventArgs.NewItem.View}");
break;
case NotifyCollectionChangedAction.Move:
Debug.LogError($"移动数据：{eventArgs.NewItem.View}");
break;
case NotifyCollectionChangedAction.Remove:
Debug.LogError($"删除数据：{eventArgs.OldItem.View}");
break;
case NotifyCollectionChangedAction.Replace:
Debug.LogError($"替换数据：{eventArgs.NewItem.View} {eventArgs.OldItem.View}");
break;
case NotifyCollectionChangedAction.Reset:
Debug.LogError($"重置数据：{eventArgs.SortOperation.IsSort} {eventArgs.SortOperation.IsClear} {eventArgs.SortOperation.IsReverse}");
break;
default:
throw new ArgumentOutOfRangeException();
}
}
}
}2、List ObservableCollections Filter 过滤
cs
using ObservableCollections;
using UnityEngine;
namespace Aladdin.Standard.Observable.Collections.List
{
public class ObservableListFilter : MonoBehaviour
{
protected readonly ObservableList<int> observableList = new ObservableList<int>();
public void Start()
{
this.observableList.Add(1);
this.observableList.Add(20);
this.observableList.AddRange(new[] { 30, 31, 32 });
foreach (int value in this.observableList)
{
Debug.LogError($"未过滤：{value}");
}
ISynchronizedView<int, string> observableListSynchronizedView = this.observableList.CreateView((value) => $"过滤: {value}");
Debug.LogError($"数据长度：{observableListSynchronizedView.Count} ========================");
observableListSynchronizedView.AttachFilter(value => value % 2 == 0);
foreach (string value in observableListSynchronizedView)
{
Debug.LogError($"{value}");
}
Debug.LogError($"数据长度：{observableListSynchronizedView.Count} ========================");
observableListSynchronizedView.AttachFilter(x => x % 2 == 1);
foreach (string value in observableListSynchronizedView)
{
Debug.LogError($"{value}");
}
Debug.LogError($"数据长度：{observableListSynchronizedView.Count} ========================");
observableListSynchronizedView.Dispose();
}
}
}3、List ObservableCollections Sort And Reverse（排序和反转）
cs
using System.Collections.Generic;
using ObservableCollections;
using UnityEngine;
namespace Aladdin.Standard.Observable.Collections.List
{
public class ObservableListSortAndReverse : MonoBehaviour
{
protected readonly ObservableList<int> observableList = new ObservableList<int>();
public void Start()
{
this.observableList.AddRange(new[] { 1, 301, 20, 50001, 4000 });
foreach (int value in this.observableList)
{
Debug.LogError($"正常数据：{value}");
}
ISynchronizedView<int, string> observableListSynchronizedView = this.observableList.CreateView((value) => $"数据: {value}");
Debug.LogError($"数据长度：{observableListSynchronizedView.Count} ========================");
observableListSynchronizedView.AttachFilter(value => value % 2 == 0);
foreach (string value in observableListSynchronizedView)
{
Debug.LogError($"{value}");
}
Debug.LogError($"======================== 数据正常过滤 ========================");
this.observableList.Reverse();
foreach (string value in observableListSynchronizedView)
{
Debug.LogError($"{value}");
}
Debug.LogError($"======================== 数据反转数据长度 ========================");
observableListSynchronizedView.ResetFilter();
foreach (string value in observableListSynchronizedView)
{
Debug.LogError($"{value}");
}
Debug.LogError($"======================== 取消数据过滤：{observableListSynchronizedView.Count} ========================");
this.observableList.Sort();
foreach (string value in observableListSynchronizedView)
{
Debug.LogError($"{value}");
}
Debug.LogError($"======================== 数据排序 Sort ========================");
this.observableList.Sort(new DescendantComparer());
foreach (string value in observableListSynchronizedView)
{
Debug.LogError($"{value}");
}
Debug.LogError($"======================== 数据排序 自定义 ========================");
observableListSynchronizedView.Dispose();
}
struct DescendantComparer : IComparer<int>
{
public int Compare(int x, int y)
{
return y.CompareTo(x);
}
}
}
}4、List ObservableCollections Subscribe（数据事件订阅）
cs
using System.Collections.Generic;
using ObservableCollections;
using R3;
using UnityEngine;
namespace Aladdin.Standard.Observable.Collections.List
{
/// <summary> 这里主要是测试集合添加数据移除数据的回调测试, Package: ObservableCollections.R3 </summary>
public class ObservableListSubscribe : MonoBehaviour
{
protected readonly ObservableList<int> observableList = new ObservableList<int>();
public void Start()
{
this.observableList.ObserveAdd().Subscribe(this.ObservableListAdd);
this.observableList.ObserveChanged().Subscribe(this.ObservableListChanged);
this.observableList.ObserveRemove().Subscribe(this.ObservableListRemove);
this.observableList.ObserveReplace().Subscribe(this.ObservableListReplace);
this.observableList.ObserveMove().Subscribe(this.ObservableListMove);
this.observableList.ObserveReset().Subscribe(this.ObservableListReset);
this.observableList.ObserveClear().Subscribe(this.ObservableListClear);
this.observableList.ObserveReverse().Subscribe(this.ObservableListReverse);
this.observableList.ObserveSort().Subscribe(this.ObservableListSort);
this.observableList.ObserveCountChanged().Subscribe(this.ObservableListCountChanged);
this.observableList.Add(1);
this.observableList.Add(20);
this.observableList.AddRange(new[] { 30, 31, 32 });
this.observableList[1] = 60;
this.observableList.Move(1, 0);
this.observableList.RemoveAt(0);
this.observableList.Move(1, 0);
this.observableList.Sort();
this.observableList.Sort(new DescendantComparer());
foreach (int value in this.observableList)
{
Debug.LogError($"{value}");
}
}
struct DescendantComparer : IComparer<int>
{
public int Compare(int x, int y)
{
return y.CompareTo(x);
}
}
internal void ObservableListCountChanged(int count)
{
Debug.Log($"数据长度变动：{count}");
}
internal void ObservableListSort((int Index, int Count, IComparer<int> Comparer) sortTuple)
{
Debug.Log($"数据排序：{sortTuple.Index} {sortTuple.Count} {sortTuple.Comparer}");
}
internal void ObservableListReverse((int Index, int Count) reverseTuple)
{
Debug.Log($"数据反转：{reverseTuple.Index} {reverseTuple.Count}");
}
internal void ObservableListClear(Unit unit)
{
Debug.Log($"数据清理：{unit}");
}
internal void ObservableListReset(CollectionResetEvent<int> collectionEvent)
{
Debug.Log($"数据重置：{collectionEvent.Index} isClear={collectionEvent.IsClear} isReverse={collectionEvent.IsReverse} isSort={collectionEvent.IsSort}");
}
internal void ObservableListMove(CollectionMoveEvent<int> collectionEvent)
{
Debug.Log($"数据移动：ni={collectionEvent.NewIndex} oi={collectionEvent.OldIndex} v={collectionEvent.Value}");
}
internal void ObservableListChanged(CollectionChangedEvent<int> changedEvent)
{
Debug.Log($"数据变动：o={changedEvent.OldItem} n={changedEvent.NewItem}");
}
internal void ObservableListReplace(CollectionReplaceEvent<int> replaceEvent)
{
Debug.Log($"数据替换：o={replaceEvent.OldValue} n={replaceEvent.NewValue}");
}
internal void ObservableListRemove(CollectionRemoveEvent<int> removeEvent)
{
Debug.Log($"删除数据：o={removeEvent.Value}");
}
internal void ObservableListAdd(CollectionAddEvent<int> addEvent)
{
Debug.Log($"添加数据：{addEvent}");
}
}
}
