public interface Context
extends ContextItem

A Context is a mapping from a name (ContextKey) to a value (ContextItem)

For example, for CFA-1, there is only one name ("caller"); and the context maps "caller" to an IMethod

As another example, for CPA, there would be name for each parameter slot ("zero","one","two"), and the Context provides a mapping from this name to a set of types. eg. "one" -> {java.lang.String, java.lang.Date}
