Brian Goetz Provides an Updated "State of the Lambda: Libraries Edition"
Recently, I've been investigating the methods Java provides for developing desktop applications that efficiently utilize multicore processors. Java 7's Fork/Join Framework is the current focus of my investigation. But, Brian Goetz has just provided an update on the State of the Lambda: Libraries Edition, which tells us lots about the current status of what's coming up in Java 8, where Project Lambda will introduce Lambda Expressions into Java.
It probably shouldn't be a big surprise, but implementing Lambda Expressions in Java 8 is going to have a very wide-ranging impact, on everything from the Collections framework to "laziness" to streams to parallelism to mutative operations... Brian takes the time to go into the details on these and other aspects of Lambda Expressions as the current work on Java 8 is progressing.
This document describes the design approach taken in the rough prototype that has been implemented in the Lambda Project repository. It is intended as a working straw-man proposal; the final version may look different, but there is a working design and implementation that may now serve as a jumping-off point for discussions.
If the implementation of Lambda Expressions in Java 8 is of considerable importance to you, this is a must read. The final implementation is no where near final at this point, and Brian is in essence asking people for suggestions. Take advantage of the offer to comment -- but, first, take the time to read Brian's State of the Lambda: Libraries Edition.
