 The Eclipse 4 Application Platform manages state and services using a set of _contexts_; this information is used for injection. 
-Contexts are used as the sources for [Dependency Injection](https://github.com/eclipse-platform/eclipse.platform.ui/blob/master/docs/Eclipse4_RCP_Dependency_Injection.md).

 In this respect, they are somewhat analogous to _modules_ in Guice. 
 Normally code should not have to use or know about the context.

 A context (a IEclipseContext) is a hierarchical key-value map. The keys are strings, often Java class names, and the values are any Java object. Each context has a parent, such that contexts are linked together to form a tree structure. When a key is not found in a context, the lookup is retried on the parent, repeating until either a value is found or the root of the tree has been reached.
