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

/**
 * A resource mapping context is provided to a resource mapping when traversing
 * the resources of the mapping. The type of context may determine what resources
 * are included in the traversals of a mapping.
 * 
 * There are currently two resource mapping contexts: the local mapping context
 * (represented by the singleton {@link #LOCAL_CONTEXT}),
 * and {@link RemoteResourceMappingContext}. Implementors of {@link ResourceMapping}
 * should not assume that these are the only valid contexts (in order to allow future
 * extensibility). Therefore, if the provided context is not of one of the above mentioned types,
 * the implementor can assume that the context is a local context.
 * 
 * 
 * This class may be subclassed by clients; this class is not intended to be
 * instantiated directly.
