Examples of RepositoryItemUid

org.sonatype.nexus.proxy.item.RepositoryItemUid
Repository item UID represents a key that uniquely identifies a resource in a repository. Every Item originating from Nexus, that is not "virtual" is backed by UID with reference to it's originating Repository and path within that repository. UIDs are immutable.
Note about "paths" used by this class. UID Paths are not FS file paths! They are always same on every platform, they are more "URL-like" hierarchical paths. Separator is always same (see {@link RepositoryItemUid#PATH_SEPARATOR}) and UIDs does not support notion of "relative paths". They always start with path separator and have 0 or more path elements separated by path separator. They might or might not end with a path separator, telling do you deal with a "collection" (aka "directory" or "folder") or not (represented by {@link StorageCollectionItem}). Still, actual checking for file or collection is NOT recommended using checks for UID ending with a path separator, you'd do the by retrieving item and something like {@code item intanceof StorageCollectionItem}!
Few examples of UID paths:
```
 / /foo /foo/bar/folder/ 
```
Constructing UID instances that does not follow these requirements might lead to unexpected results! This might change in future, where the path will be validated and sanitized (and by throwing exceptions show you the location of bug in the code that tried to use invalid path for UID constructor). For path utilities, see {@link PathUtils}. @author cstamas
