Defined in:
lib/netcdf/group.rb

Overview

A Group is a logical collection of Variables. The Groups in a Dataset form a hierarchical tree, like directories on a disk. A Group has a name and optionally a set of Attributes. There is always at least one Group in a dataset, the root Group, whose name is the empty string.

Immutable if setImmutable() was called.
