H5 Objects Describe the properties of the different H5 objects H5 File H5 Group H5 Dataset H5 Dataspace H5Attribute H5 Type H5 Reference H5 objects have some accessible properties. All the properties name are case insensitive (except for the path or objects names). The following properties can be accessed: name: the filename; size: the file size; version: the HDF5 library version; root: the root group "/". If the field name starts with '/', then it is considered as a path and the returned value is the H5 object corresponding to this path. The following properties can be accessed: attributes: the attributes names; groups: the subgroups names; datasets: the datasets names; types: the types names; externals: the external links names; softs: the soft links names; danglings: the dangling links names; hards: the hard links names; links: the links names and types; name: the group name; path: the group path. If the field name is not in the previous list, then it is considered as a local path to another H5 object. The following properties can be accessed: attributes: the attributes names; type: the dataset type; dataspace: the dataset space; data: the dataset data; name: the group name; path: the group path. If the field name is not in the previous list, then it is considered as an attribute name. The following properties can be accessed: dims: the dataspace dimensions; extents: the dataspace max dimensions; type: the dataspace type: "scalar", "simple" or "null"; name: the parent name. path: the parent path. The following properties can be accessed: type: the attribute type; dataspace: the attribute dataspace; data: the attribute data; name: the attribute name. path: the parent path. The following properties can be accessed: class: the type class; type: the type name; size: the size in bytes; nativetype: the native type associated with this type; nativesize: the size of the native type. name: the parent name. path: the parent path. H5 Reference object wrap an hypermatrix object where elements are a reference to an H5 object. h5attr h5close h5cp h5dataset h5dump h5exists h5flush h5get h5group h5isAttr h5isFile h5isGroup h5isRef h5isSet h5isSpace h5isType h5label h5ln h5ls h5mount h5mv h5open h5read h5rm h5umount h5write h5writeattr 5.5.0 HDF5 module introduced.
