Declarative caching and invalidation
[CacheConfiguration( AbsoluteExpiration = 10 )]
class CustomerServices
{
[Cache]
public static Customer GetCustomer(int id)
{
return DetailsSkipped();
}
[InvalidateCache(nameof(GetCustomer))]
public static void RenameCustomer(int id, string newName)
{
// Parameter 'id' of 'GetCustomer' method matched by name.
DetailsSkipped();
}
}
- Add caching to a method with a simple custom attribute.
- Cache key automatically generated based on method name and parameter values.
- Invalidate cached method with custom attribute and automatic, build-time parameter matching.
- Fully customizable.
Object-oriented invalidation
internal class AccountServices
{
[Cache]
public static Account GetAccount(int id)
{
// Add an object-oriented dependency to GetMethod.
CachingServices.CurrentContext.AddDependency(new AccountDependency(id));
return DetailsSkipped();
}
[Cache]
public static Account[] GetAccountsOfCustomer(int customerId)
{
// Implicitly adds dependencies to Account(1) and Account(2).
return GetAccountIds(customerId).Select(GetAccount).ToArray();
}
public static void UpdateAccount(Account account)
{
// Invalidates both GetAccount and GetAccountsOfCustomers.
CachingServices.Invalidation.Invalidate(
new AccountDependency(account.Id));
}
}
- Improve seperation of concerns between readers and updaters.
- Dependencies of called methods automatically added to the caller context.
