This site is intended to assist individuals creating tools to give or assist AJDT/AspectJ. Please subscribe to these pages with any relevant information, eg sample rule utilising the AJDT and/or AspectJ APIs.
This site may be out of big date. The purpose is to modify this page for AJDT 1.6.1, but we have not have opportunity because of this yet. Be sure to understand that a number of something about page may no longer become proper. When you have any questions, please submit them to the subscriber list ajdt-dev.

Getting crosscutting connection info from AJDT
If you’re building an eclipse plugin and call for accessibility crosscutting info whenever a project is built, you can enter a listener with AJDT. Your plug-in should rely on org.eclipse.ajdt.core, org.eclipse.core.resources and org.eclipse.jdt.core, and org.aspectj.weaver. Into the org.eclipse.ajdt.core plug-in there can be an IAdviceChangedListener user interface with a single adviceChanged() way.
Enroll this utilizing the AJBuilder lessons such as this (in your plug-in’s start() way of instance):
Currently (AJDT 1.6) this really is labeled as after every acquire of an AspectJ project (for example. معلومات عن رونالدو every *potential* guidance change). In a future launch this may be enhanced to-be merely called in the event that guidance possess actually altered. AJDT/UI makes use of this system to modify the tangerine arrow image decorator.
Crosscutting ideas can then getting obtained from the AJProjectModelFacade lessons. Here is an illustration with some pseudo-code possible adjust:
Several notes about this:
- The API might have some small changes in the long term. Please send a message to the ajdt-dev mailing list if things about page may be out of day.
- The AJProjectModelFacade item try a lightweight entrance into the AspectJ community. It is simply appropriate before the after that build. So, never save them. Use them and dispose as required.
- AJProjectModelFacade stuff best include facts following the very first effective build. Possible call the possessModel() solution to see if an AspectJ design is present when it comes to task.
- Perhaps you have realized, you receive the partnership in both directions. Read AJRelationshipManager for all the complete selection of connections, to help you just request the connection type you are interested in.
- IRelationship.getSourceHandle() and IRelationship.getobjectives() return chain that represent AspectJ aspect manages. You can use the next AJProjectModelFacade ways to become model aspects:
- toProgramElement(String) — profits IProgramElement. From this point you’ll be able to obtain information about the pointcut, intertype component, or declare element.
- programElementToJavaElement(String) or programElementToJavaElement(IProgramElement) — returns IJavaElement. From here you are able to connect into JDT tooling.
- There is no criteria to join up a recommendations altered listener. You can get use of the crosscutting product whenever you want (assuming that your panels has already established a fruitful acquire) utilising the preceding rule:
Collection Devices in AJDT
JDT produces collection models (cases of ICompilationproduct) for .java documents. AJDT produces compilation devices for .aj data, which are cases of AJCompilationUnit (which implements ICompilationdevice). The course AJCompilationUnitManager (within the org.eclipse.ajdt.core plug-in) have some of good use practices relating to this, instance:
From an AJCompilationUnit you are able to acquire different architectural information such as getAllTypes(). The principal kind for ”.aj” data is usually an element, in fact it is represented by AspectElement lessons, containing aspect-specific means for example getPointcuts() and getAdvice(). These return furthermore aspect-specific aspects such as PointcutElement and AdviceElement.
Since AJDT 1.6.2 for Eclispe 3.4, we utilize the Eclipse weaving provider to weave into JDT. One pair of join factors which are urged are those about the production of CompilationUnit objects. In the event the file have try *.aj file, AJCompilationUnit is done versus a general coffee CompilationUnit.
Obtaining the belongings in an AJCompilationUnit
Because JDT needs that most resource it truly does work with is true Java rule, JDT can not work well with AspectJ. To get for this, AJCompilationUnits keep two buffers which contain supply contents. The very first is a java suitable buffer in addition to second will be the initial articles buffer. The coffee suitable buffer will be the buffer this is certainly returned automatically when AJCompilationUnit.getContents() is known as. This buffer provides the AspectJ rule with all aspect-specific syntax stripped out. The original articles buffer includes (when you would count on) the original content material of this document.
Like in the event the initial content material buffer appears to be:
the Java compatible buffer becomes
Realize that the foundation areas in the identifiers are exactly the same both in buffers. This helps to ensure that research researching and hyperlinking works needlessly to say.
Any time you call for cooperating with the original articles of an AspectJ CompilationUnit ajUnit, you certainly can do the immediate following:
Exactly what this process does asks for the AJCU to temporarily switch its buffer into the AJ buffer from Java buffer. It is best to repeat this in a synchronized block to make sure you cannot chance different threads coming by and inadvertently using the incorrect buffer (AJDT it self doesn’t incorporate a synchronized block for this, but it should).
Utilizing the AspectJ AST parser
