AspectJ tools most notably contains the AspectJ compiler (AJC). AJC applies aspects to Java classes during compilation, fully replacing Javac for plain Java classes and also compiling native AspectJ or annotation-based @AspectJ syntax. Furthermore, AJC can weave aspects into existing class files in a post-compile binary weaving step. This library is a superset of AspectJ weaver and hence also of AspectJ runtime.

There is a newer version: 1.9.22.1

 * Slave documents are documents whose contents is defined in terms of a master
 * document. Thus, slave documents usually reflect a projection of the master document.
 * Slave documents are causally connected to the master document. This means, changes
 * of the master document have immediate effect on the slave document and vice versa.
 * 
 * A slave document manager creates slave documents for given master documents, manages the
 * life cycle of the slave documents, and keeps track of the information flow between
 * master and slave documents. The slave document manager defines the construction rules of the
 * slave documents in terms of the master document.
 * 
* In order to provided backward compatibility for clients of ISlaveDocumentManager, extension
 * interfaces are used to provide a means of evolution. The following extension interfaces
 * exist:
 * 
 * 
 *  {@link org.eclipse.jface.text.ISlaveDocumentManagerExtension} since version 3.0 extending the protocol
 *      with an access to all managed slave document for a given master document.
