NoCache attribute

RSS

Cache aspect can be applied to entire class. In this case all virtual and abstract members will be cached. However you can use the NoCache> attribute to exclude particular members from caching.

NoCache.cs

using BLToolkit.Reflection;

namespace HowTo.Aspects
{
    [Cache]
    public abstract class NoCacheTestClass
    {
        public static int Value;

        public virtual int CachedMethod(int p1, int p2)
        {
            return Value;
        }

        [NoCache]
        public virtual int NoCacheMethod(int p1, int p2)
        {
            return Value;
        }

        public static NoCacheTestClass CreateInstance()
        {
            // Use TypeAccessor to create an instance of an abstract class.
            //
            return TypeAccessor<NoCacheTestClass>.CreateInstance();
        }
    }

    [TestFixture]
    public class NoCacheAttributeTest
    {
        [Test]
        public void Test()
        {
            NoCacheTestClass t = TypeAccessor<NoCacheTestClass>.CreateInstance();

            NoCacheTestClass.Value = 1; Assert.AreEqual(1, t.CachedMethod(1, 1));
            NoCacheTestClass.Value = 2; Assert.AreEqual(1, t.CachedMethod(1, 1)); // no change

            NoCacheTestClass.Value = 3; Assert.AreEqual(3, t.NoCacheMethod(2, 1));
            NoCacheTestClass.Value = 4; Assert.AreEqual(4, t.NoCacheMethod(2, 1));
        }
    }
