Class ContextLink

java.lang.Object
  ix.util.context.ContextLink

public final class ContextLink
extends java.lang.Object

An element in a chain of associations between contexts and values.

A chain of ContextLinks is used to map contexts to values (Objects). The public constructors create a 1-link chain. This normally specifies a default, initial, or top-level value (typically one associated with the root context). Further links are normally added by calling the Context.setInContext method; this ensures that the resulting chain can be processed correctly by the Context.getInContext method, which requires that entries for newer (higher-numbered) contexts appear before those for older ones.
