Method Detail

canEncapsulate	back to summary
public static boolean canEncapsulate(String name) Return true if a resource can be encapsulated. Resource with names ending in ".class" or "/" cannot be encapsulated. Resource names that map to a legal package name can be encapsulated.

mayTranslate	back to summary
private static boolean mayTranslate(String name, int off, int len) Returns `true` if the element in a resource name is a candidate to translate to the element of a file path.

toFilePath	back to summary
public static Path toFilePath(Path dir, String name) throws IOException Returns a file path to a resource in a file tree. If the resource name has a trailing "/" then the file path will locate a directory. Returns `null` if the resource does not map to a file in the tree file.

toPackageName	back to summary
public static String toPackageName(String name) Derive a package name for a resource. The package name returned by this method may not be a legal package name. This method returns null if the resource name ends with a "/" (a directory) or the resource name does not contain a "/".

toResourceName	back to summary
public static String toResourceName(Path dir, Path file) Returns a resource name corresponding to the relative file path between `dir` and `file`. If the file is a directory then the name will end with a "/", except the top-level directory where the empty string is returned.

toSafeFilePath	back to summary
private static Path toSafeFilePath(FileSystem fs, String name) Map a resource name to a "safe" file path. Returns `null` if the resource name cannot be converted into a "safe" file path. Resource names with empty elements, or elements that are "." or ".." are rejected, as are resource names that translates to a file path with a root component.
