InvocationScope

public class InvocationScope
extends Object implements Scope

java.lang.Object
↳	com.android.tradefed.guice.InvocationScope

Scopes a single Tradefed invocation.

The scope can be initialized with one or more seed values by calling seed(key, value) before the injector will be called upon to provide for this key. A typical use is for a test invocation to enter/exit the scope, representing an invocation Scope, and seed configuration objects. For each key inserted with seed(), you must include a corresponding binding:


   bind(key)
       .toProvider(SimpleScope.seededKeyProvider())
       .in(InvocationScoped.class);

FIXME: Possibly handle multi objects (like lists).

Summary

Public constructors
`InvocationScope()`

Public methods
`void`	`enter()` Start marking the scope of the Tradefed Invocation.
`void`	`exit()` Mark the end of the scope for the Tradefed Invocation.
`static InvocationScope`	`getDefault()`
`<T> Provider<T>`	`scope(Key<T> key, Provider<T> unscoped)`
`<T> void`	`seed(Key<T> key, T value)` Seed a key/value that will be available during the TF invocation scope to be used.
`<T> void`	`seed(Class<T> clazz, T value)` Seed a key/value that will be available during the TF invocation scope to be used.
`void`	`seedConfiguration(IConfiguration config)` Interface init between Tradefed and Guice: This is the place where TF object are seeded to the invocation scope to be used.
`static <T> Provider<T>`	`seededKeyProvider()` Returns a provider that always throws exception complaining that the object in question must be seeded before it can be injected.
