Interface ObjectFactory.Context

All Known Implementing Classes:

ExpCompiler.Factory.Context

Enclosing class:

ObjectFactory<V>

public static interface ObjectFactory.Context

This is for testing only.

Context contain the Factory implementation specific non-default values and mechanism for overriding the default instance type returned by the Factory. Factory implementation can extend the Context interface to capture its specific override values. If, for example, a Factory implementation uses a ThreadLocal to override the default instance type for unit tests, then the Context will hold the current value of the ThreadLocal. Getting the Context, clears the ThreadLocal value. This allows the tester who wishes to create code that will provide a wrapper around the default instance type to register their wrapper class name with the ThreadLocal, and, within the wrapper constructor, get the Context, get a default instance, and then restore the Context.
