Interface RuntimeAttributeContainer

public interface RuntimeAttributeContainer

A runtime attribute container is an object that accepts key-value pairs as runtime attributes. Runtime attributes are used to store arbitrary values that cannot be determined at the time of the implementation of the object.
This is usually implemented using a simple map. However, the map should be allocated only if an attribute is set in order to save memory.
They are usually not written to/read from persistent storage when the object is being serialized/deserialized, thus the name runtime attributes. The dynamic property access mechanism implemented by the PropertyAccessUtil class supports runtime attribute containers.
