I noticed the AspectJ compiler doesn't use a parser generator. Why is that?
AspectJ Frequently Asked QuestionsIn AspectJ 1.0, the PARSER for ajc is written by hand. This choice was made with full awareness of the generator tools out there. (Jim had for example used the excellent javacc tool for building the parser for JPython (now Jython)). One of the reasons that AspectJ uses a hand-written parser is that using javacc taught Jim about the LL-k design for parsers (pioneered by antlr). As opposed to the state-machine parsers produced by yacc, these parsers are very readable and writable by humans.
Related QuestionsDo I have to use the AspectJ compiler?
AspectJ Frequently Asked QuestionsThe AspectJ compiler or weaver is required at some point, but many people can use AspectJ without changing their build or deployment process significantly. For aspects that are not required to compile, you can use the AspectJ binary weaver, run at build-time or class-load-time. You can write aspects using the original code style (which must be compiled with the AspectJ compiler) or using the annotation style new in AspectJ 5 (which may be compiled with Javac or the AspectJ compiler).
Related QuestionsWhat Java virtual machine (JVM) do I use to run the AspectJ compiler?
AspectJ Frequently Asked QuestionsUse the latest, greatest, fastest JVM you can get your hands on for your platform. The compiler's performance is dependent on the performance of the JVM it is running on, so the faster a JVM you can find to run it on, the shorter your compile times will be. At a minimum you need to use a Java 2 or later JVM to run the compiler (J2SE 1.3 for AspectJ 1.1). We realize that this constraint can be a problem for users who don't currently have a Java 2 JVM available.
Related QuestionsHow do I write bugs for the AspectJ compiler?
AspectJ Frequently Asked QuestionsThe best compiler bug report is a reproducible test case, standalone code that demonstrates the problem. Sometimes with aspects, a test case requires several files, if not some way to capture the behavior. Here's how we recommend submitting test cases: Write the test case so that when the compiler bug is fixed, the test completes normally without output (e.g., expected compiler errors are issued, or classes produced run correctly). This usually means writing one or more source files.
Related QuestionsCan I use AspectJ with J2EE?
AspectJ Frequently Asked QuestionsJSP: It is possible to use AspectJ to affect code in JSPs by precompiling them into Java sources and compiling these with ajc. This can be used, e.g., to customize displays by turning on and off custom JSP taglibs. The mapping from a given jsp source to java package and class name is not standardized, which means doing this imposes dependencies on specific container versions. EJB: AspectJ supports a wide variety of aspects for EJBs.

AspectJ Frequently Asked QuestionsBut at this time, unfortunately not. The two compilers are just not at all compatible.

Related QuestionsI just noticed that my Touareg doesn't appear to have any antennae. Isn't that odd?
Volkswagen Touareg Frequently-Asked QuestionsIt would be odd if it were true. The Touareg actually has several antennas, including AM radio, FM radio, long-range remote control, four short-range remote control, four tire pressure monitor, and in some vehicles, GPS, and OnStar antennas. Some of these antennas, including the GPS and radio antennas are in the rear glass on either side of the vehicle.
Related QuestionsHow do I use scanf() and gets() functions with the PICC/PICC18 compiler ?
HI-TECH Software Frequently Asked QuestionsHow do I use scanf() and gets() functions with the PICC/PICC-18 compiler? A. The gets() function is not supplied by the compiler. Becuase gets() will get a string from a programer specified input, such as the serial port, it is easier for the programer to write this function then for it to be supplied in a library. There is a console get string function, cgets(), that will read string from an input using console formatting. The cgets() function is available in the cgets.

Is it safe to use AspectJ in my product plans?
AspectJ Frequently Asked QuestionsYou may use AspectJ in your product or project with little risk. Several factors play a role in reducing the risk of adopting this new technology: AspectJ is an addition to Java, and can be introduced into a project in a way that limits risk. See Q: How should I start using AspectJ? for some suggestions on how to do this. The AspectJ compiler accepts standard Java as input and produces standard Java bytecode as output. In 1.

Related QuestionsCan I give the parser part-of-speech (POS) tagged input and force the parser to use those tags?
The Stanford NLP (Natural Language Processing) GroupYes, you can. However, you will need to provide correctly tokenized input if you want to provide POS-annotated input. (That is, the input must be tokenized and normalized exactly as the material in the treebank underlying the grammar is.) Read the Javadocs for the main method of the LexicalizedParser class. The relevant options are -sentences (see above), -tokenized, and -tagSeparator.

It can be used in small acrylic shower units, which don't have high heat demands due to size and wall materials.

Related QuestionsWhy can't I use my backup generator for on-site power production?
Distributed Energy Program: Frequently Asked QuestionsThe primary problem with using backup generators for on site power generation concerns their emissions, NOx and SOx, although noise and durability can also be problems. Most urban areas limit the maximum number of hours that IC engine driven backup generators can be operated each year because of their NOx and SOx emission levels. Generators for CHP systems can operate upwards of 8000 hours per year which greatly exceed backup generator usage, typically limited to less than 200 hours per year.
