walkModuleImage
public static void walkModuleImage(File image, JRTUtil.JrtFileVisitor<Path> visitor, int notify) throws IOExceptionGiven the path of a modular image file, this method walks the archive content and notifies the supplied visitor about packages and files visited. The file system contains the following top level directories: /modules/$MODULE/$PATH /packages/$PACKAGE/$MODULE The latter provides quick look up of the module that contains a particular package. However, this method only notifies its clients of the entries within the modules (former) sub-directory. Clients can decide which notifications they want to receive. SeeNOTIFY_ALL

andNOTIFY_MODULES
.- Parameters:
image
- a java.io.File handle to the JRT image.visitor
- an instance of JrtFileVisitor to be notified of the entries in the JRT image.notify
- flag indicating the notifications the client is interested in.- Throws:
IOException
