Abstract
An object system provides composable object execution environment extensions with an object model that defines a framework with contexts, policies, policy makers and activators that act as object creation-time, reference creation-time and call-time event sinks to provide processing of effects specific to the environment extensions. At object creation time, an object instantiation service of the object system delegates to the activators to establish a context in which the object is created. The context contains context properties that represent particular of the composable environment extensions in which the object is to execute. The context properties also can act as policy makers that contribute policies to an optimized policy set for references that cross context boundaries. The policies in such optimized sets are issued policy events on calls across the context boundary to process effects of switching between the environment extensions of the two contexts.
