public class JavaManager
A JavaManager
is an implementation of the JavaFileProvider
interface. It provides structured access to the contents of Java class and source files visible through a Project
or through a set of source and classpaths.
There is also access to a JavaClassLocator
instance for searching for the classes and subpackages contained in a package, and for finding an URL associated with a Java source or class file.
By default, the JavaFile and JavaClass (as well as SourceFile and SourceClass) instances retrieved through this API saved in a cache. Clients are encouraged to use the provided CacheSupport
API to provide indication as to when the cache is used, and when it is no longer in use (and can be flushed). Clients can also force a cache flush to occur.

getAnyJavaManager(Project project) Fetch a JavaManager instance in a fail-safe manner. |
static Project |
getDefiningProject(Context context, java.net.URL url) Finds the project that defines the specified URL. The method searches the currentProject , the jdk libraries, the project's libraries, it will repeat the same search for the upstream dependencies and if it still not found, it will search all the other projects in the workspace. |
