+/**
+ * <p>
+ * This class is a container for the information reported about an HDF5 Object
+ * from the H5Gget_obj_info() method.
+ * <p>
+ * The fileno and objno fields contain four values which uniquely identify an
+ * object among those HDF5 files which are open: if all four values are the same
+ * between two objects, then the two objects are the same (provided both files
+ * are still open). The nlink field is the number of hard links to the object or
+ * zero when information is being returned about a symbolic link (symbolic links
+ * do not have hard links but all other objects always have at least one). The
+ * type field contains the type of the object, one of H5G_GROUP, H5G_DATASET, or
+ * H5G_LINK. The mtime field contains the modification time. If information is
+ * being returned about a symbolic link then linklen will be the length of the
+ * link value (the name of the pointed-to object with the null terminator);
+ * otherwise linklen will be zero. Other fields may be added to this structure
+ * in the future.
+ *
+ * @deprecated  Not for public use. It is not used by the library.
+ *    This class assumes that an object can contain four values which uniquely identify an
+ *    object among those HDF5 files which are open. This is no longer valid in future
+ *    HDF5 releases.
