These pages is intended to aid individuals building gear to increase or use AJDT/AspectJ. Kindly donate to these pages with any related details, such as for example sample code using the AJDT and/or AspectJ APIs.
This page may be out of go out. All of our objective is upgrade these pages for AJDT 1.6.1, but we not have time for this yet. Be sure to keep in mind that a few of what’s with this webpage may no much longer become proper. For those who have any questions, please send them to the email list ajdt-dev.

Acquiring crosscutting partnership info from AJDT
If you’re developing an eclipse plug-in and need the means to access crosscutting information whenever a project is made, you’ll subscribe a listener with AJDT. Your own plug-in will need to be determined by org.eclipse.ajdt.core, org.eclipse.core.resources and org.eclipse.jdt.core, and org.aspectj.weaver. From inside the org.eclipse.ajdt.core plug-in you will find an IAdviceChangedListener program with an individual adviceChanged() technique.
Enroll this aided by the AJBuilder lessons in this way (inside plug-in’s start() method for sample):
Presently (AJDT 1.6) that is labeled as after each and every acquire of an AspectJ job (in other words. every *potential* guidance changes). In a future launch this can be optimized are merely called in the event that advice enjoys actually altered. AJDT/UI uses this system to update the lime arrow graphics decorator.
Crosscutting information can then end up being obtained from the AJProjectModelFacade course. Discover an illustration with many pseudo code possible adapt:
A number of records about this:
- The API could have some slight changes in the long term. Be sure to send a note towards ajdt-dev mailing list if anything on this subject web page is beyond big date.
- The AJProjectModelFacade item is actually a light-weight access to the AspectJ world. It can be legitimate until the then create. Thus, you should not keep them. Make use of them and dispose as required.
- AJProjectModelFacade items merely have information after the first effective build. You’ll be able to call the possessModel() method to see if an AspectJ product is present for all the job.
- Perhaps you have realized, you receive the relationship in directions. Discover AJRelationshipManager the full range of interactions, so you can just request the relationship types you find attractive.
- IRelationship.getSourceHandle() and IRelationship.getgoals() return Strings that represent AspectJ component handles. You need the following AJProjectModelFacade methods to convert to model characteristics:
- toProgramElement(sequence) — returns IProgramElement. From here possible obtain information regarding the pointcut, intertype component, or declare aspect.
- programElementToJavaElement(sequence) or programElementToJavaElement(IProgramElement) — returns IJavaElement. From here you can easily catch into JDT tooling.
- There’s absolutely no necessity to register an information altered listener. You can aquire access to the crosscutting model at any time (so long as your panels has received a fruitful create) with the next laws:
Compilation Units in AJDT
JDT produces compilation devices (instances of ICompilationproduct) for .java data files. AJDT produces collection products for .aj documents, which are instances of AJCompilationUnit (which implements ICompilationUnit). The category AJCompilationUnitManager (in the org.eclipse.ajdt.core plug-in) consists of some useful means relating to this, particularly:
From an AJCompilationUnit it is possible to get different architectural records particularly getAllTypes(). The primary type for “.aj” records is normally an element, which is represented by the AspectElement course, which contains aspect-specific methods such as getPointcuts() and getAdvice(). These return more aspect-specific characteristics such as PointcutElement and AdviceElement.
Since AJDT 1.6.2 for Eclispe 3.4, we utilize the Eclipse weaving services to incorporate into JDT. One collection of join details which are advised are those regarding the creation of CompilationUnit things. When the document enjoys was *.aj file, AJCompilationUnit is generated rather than a typical Java Compilationproduct.
Acquiring the belongings in an AJCompilationUnit
Because JDT expects that every supply it works with does work Java code, JDT doesn’t work better with AspectJ. In order to get surrounding this, AJCompilationUnits maintain two buffers containing provider articles. The first is a java compatible buffer as well as the 2nd could be the earliest information buffer. The java suitable buffer will be the buffer that is returned automagically when AJCompilationUnit.getContents() is known as. This buffer provides the AspectJ code with aspect-specific syntax removed
Like in the event that earliest content buffer seems like:
the Java compatible buffer becomes
Notice that the foundation locations regarding the identifiers are identical in buffers. This helps to ensure that guide searching and hyperlinking work not surprisingly.
In the event that you call for dealing with the initial contents of an AspectJ CompilationUnit ajproduct, you can do the following:
What this method really does requests for the AJCU to briefly turn their buffer towards AJ buffer through the Java buffer. It is best to do this in a synchronized block to make sure you do not exposure other posts coming by and unintentionally with the completely wrong buffer (AJDT by itself doesn’t utilize a synchronized block https://datingranking.net/fruzo-review/ for this, nevertheless should).
Making use of the AspectJ AST parser
