+ * This class is a container for the information reported about an HDF5 Object + * from the H5Gget_obj_info() method. + *
+ * 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 This is no longer valid in future + * HDF5 releases. + */ + +@Deprecated +public class HDF5GroupInfo { + long[] fileno; + long[] objno; + int nlink; + int type; + long mtime; + int linklen; + + /** + * Container for the information reported about an HDF5 Object + * from the H5Gget_obj_info() method + */ + public HDF5GroupInfo() + { + fileno = new long[2]; + objno = new long[2]; + nlink = -1; + type = -1; + mtime = 0; + linklen = 0; + } + + /** + * Sets the HDF5 group information.
