edu.cmu.cs.crystal.annotations.AnnotationDatabase

This class is a database for annotations. It can store annotations of methods we have analyzed or of ones we have not. Either way, it does not store any AST information, so it returns Crystal objects that represent an annotation. Those who want to use this database must register the type of annotations to scan for, @see{ICrystalAnnotation}. A ICrystalAnnotation provides all the information that one needs about the annotations. An AnnotationSummary is particularly useful for finding all information relating to the method, including parameters. And just in case you were wondering...we can not use regular reflection objects here (Class, Annotation, etc.) as the files we are analyzing aren't on the classpath of the system we are running. The annotation database currently allows clients to request annotations if they provide an ITypeBinding. However, this means that Crystal needs to have parsed and analyzed the code in question to get an ITypeBinding in the first place. Instead, we would like to retrieve annotations from unanalyzed code (for example, a library). This can currently be done with @link{#getAnnosForType(IType)}, and the plan is to eventually allow methods and fields based upon the Java Model instead of the Java ASTNodes. @author ciera @author Nels Beckman
