Implement a relaxed immutability model
Immutable objects are a great help for writing thread-safe software. In the Java™ language, the primary mechanism for guaranteeing immutability is the use of final fields. But final fields must be set in constructors, and in some cases, this requirement is too restrictive. This article shows an efficient way to implement a slightly more relaxed model of immutability, using normal cached fields whose values can still be accessed safely without synchronization.
