implementing the generic interface
- by user845405
Could any one help me on implementing the generic interface for this class. I want to be able to use the below Cache class methods through an interface.
Thank you for the help!.
public class CacheStore
{
private Dictionary<string, object> _cache;
private object _sync;
public CacheStore()
{
_cache = new Dictionary<string, object>();
_sync = new object();
}
public bool Exists<T>(string key) where T : class
{
Type type = typeof(T);
lock (_sync)
{
return _cache.ContainsKey(type.Name + key);
}
}
public bool Exists<T>() where T : class
{
Type type = typeof(T);
lock (_sync)
{
return _cache.ContainsKey(type.Name);
}
}
public T Get<T>(string key) where T : class
{
Type type = typeof(T);
lock (_sync)
{
if (_cache.ContainsKey(key + type.Name) == false)
throw new ApplicationException(String.Format("An object with key '{0}' does not exists", key));
lock (_sync)
{
return (T)_cache[key + type.Name];
}
}
}
public void Add<T>(string key, T value)
{
Type type = typeof(T);
if (value.GetType() != type)
throw new ApplicationException(String.Format("The type of value passed to
cache {0} does not match the cache type {1} for key {2}",
value.GetType().FullName, type.FullName, key));
lock (_sync)
{
if (_cache.ContainsKey(key + type.Name))
throw new ApplicationException(String.Format("An object with key '{0}'
already exists", key));
lock (_sync)
{
_cache.Add(key + type.Name, value);
}
}
}
}
