ILRuntime中跨域继承
如果你想在热更DLL项目当中继承一个Unity主工程里的类
,或者实现一个主工程里的接口
,你需要在Unity主工程中实现一个继承适配器。
方法如下:
public class TestClass2Adapter : CrossBindingAdaptor
{
//定义访问方法的方法信息
static CrossBindingMethodInfo mVMethod1_0 = new CrossBindingMethodInfo("VMethod1");
static CrossBindingFunctionInfo<System.Boolean> mVMethod2_1 = new CrossBindingFunctionInfo<System.Boolean>("VMethod2");
static CrossBindingMethodInfo mAbMethod1_3 = new CrossBindingMethodInfo("AbMethod1");
static CrossBindingFunctionInfo<System.Int32, System.Single> mAbMethod2_4 = new CrossBindingFunctionInfo<System.Int32, System.Single>("AbMethod2");
public override Type BaseCLRType
{
get
{
return typeof(ILRuntimeTest.TestFramework.TestClass2);//这里是你想继承的类型
}
}
public override Type AdaptorType
{
get
{
return typeof(Adapter);
}
}
public override object CreateCLRInstance(ILRuntime.Runtime.Enviorment.AppDomain appdomain, ILTypeInstance instance)
{
return new Adapter(appdomain, instance);
}
public class Adapter : ILRuntimeTest.TestFramework.TestClass2, CrossBindingAdaptorType
{
ILTypeInstance instance;
ILRuntime.Runtime.Enviorment.AppDomain appdomain;
//必须要提供一个无参数的构造函数
public Adapter()
{
}
public Adapter(ILRuntime.Runtime.Enviorment.AppDomain appdomain, ILTypeInstance instance)
{
this.appdomain = appdomain;
this.instance = instance;
}
public ILTypeInstance ILInstance { get { return instance; } }
//下面将所有虚函数都重载一遍,并中转到热更内
public override void VMethod1()
{
if (mVMethod1_0.CheckShouldInvokeBase(this.instance))
base.VMethod1();
else
mVMethod1_0.Invoke(this.instance);
}
public override System.Boolean VMethod2()
{
if (mVMethod2_1.CheckShouldInvokeBase(this.instance))
return base.VMethod2();
else
return mVMethod2_1.Invoke(this.instance);
}
protected override void AbMethod1()
{
mAbMethod1_3.Invoke(this.instance);
}
public override System.Single AbMethod2(System.Int32 arg1)
{
return mAbMethod2_4.Invoke(this.instance, arg1);
}
public override string ToString()
{
IMethod m = appdomain.ObjectType.GetMethod("ToString", 0);
m = instance.Type.GetVirtualMethod(m);
if (m == null || m is ILMethod)
{
return instance.ToString();
}
else
return instance.Type.FullName;
}
}
}
因为跨域继承必须要注册适配器。 如果是热更DLL里面继承热更里面的类型,不需要任何注册。
appdomain.RegisterCrossBindingAdaptor(new ClassInheritanceAdaptor());
