/**
* Base class for all OpenCms VFS resources like {@link CmsFile} or {@link CmsFolder}.
*
* The OpenCms VFS resource is an important object for using the OpenCms API.
* Basically, all entries in the OpenCms VFS are considered to be "resources".
* Currently, only two types of resources exists:
* - Files, which are represented by the subclass {@link CmsFile}.
*
- Folders (also called Directories), which are represented by the subclass {@link CmsFolder}.
*
*
* If you have a resource, you can use {@link #isFile()} or {@link #isFolder()} to learn what kind of
* subclass you have. Please note that this is usually not required, as the only real difference between a
* {@link CmsFile} and a {@link CmsResource} is that the {@link CmsFile} also has the contents of the file,
* which you can obtain using {@link CmsFile#getContents()}. As long as you don't need the content, you can
* use the {@link CmsResource} for everything else. This is even more true for a {@link CmsFolder}, here you
* will need the subclass only in special cases, since the signature is identical to {@link CmsResource}.
*
* A OpenCms VFS resource can have any number of properties attached, which are represented by a {@link CmsProperty}.
* To read the properties for a resource, use {@link CmsObject#readPropertyObject(CmsResource, String, boolean)}
* or use {@link CmsObject#readPropertyObjects(CmsResource, boolean)} to read all properties of the resource.
*
