This aspect simplifies method overloading.
Note the OverloadAspect is not compatible with other type builders that generate a method body.
If you apply them along with the OverloadAspect to an abstract method, they will be igored.
OverloadAspect.cs
using NUnit.Framework;
using BLToolkit.Aspects;
using BLToolkit.Reflection;
namespace HowTo.Aspects
{
public abstract class OverloadTestObject
{
// This is a member we will overload.
//
public int Test(int intVal, string strVal)
{
return intVal;
}
// Overloaded methods simply calls a base method with same name
// and has a few parameters less or more.
//
[Overload] public abstract int Test(int intVal);
[Overload] public abstract int Test(string strVal);
[Overload] public abstract int Test(int intVal, string strVal, bool boolVal);
}
[TestFixture]
public class OverloadAspectTest
{
[Test]
public void OverloadTest()
{
OverloadTestObject o = TypeAccessor<OverloadTestObject>.CreateInstance();
Assert.AreEqual(1, o.Test(1));
Assert.AreEqual(0, o.Test("str"));
}
}
} |
BLToolkit type builder will generate the following for the class above:
[BLToolkitGenerated]
public sealed class OverloadTestObject : OverloadTestObject
{
[BLToolkitGenerated]
public override int Test(int intVal)
{
return this.Test(intVal, string.Empty);
}
[BLToolkitGenerated]
public override int Test(string strVal)
{
return this.Test(0x0, strVal);
}
[BLToolkitGenerated]
public override int Test(int intVal, string strVal, bool boolVal)
{
return this.Test(intVal, strVal);
}
