- com.massa.util.property.ReflectionPropertyAccessCache

All Implemented Interfaces:

IPropertyAccessCache

Direct Known Subclasses:

NativePropertyAccessCache
```
public class ReflectionPropertyAccessCache
extends Object
implements IPropertyAccessCache
```
Allows to cache data on read and write methods, for already encountered beans types.
All bean accesses are performed using the Java Reflection API.
This class and all performed operations are fully thread safe and can be used in a multithreaded environment.
