Examples of ucar.nc2.Dimension

ucar.nc2.Dimension
A Dimension is used to define the array shape of a Variable. It may be shared among Variables, which provides a simple yet powerful way of associating Variables. When a Dimension is shared, it has a unique name within its Group. It may have a coordinate Variable, which gives each index a coordinate value. A private Dimension cannot have a coordinate Variable, so use shared dimensions with coordinates when possible. The Dimension length must be > 0, except for an unlimited dimension which may have length = 0, and a vlen Dimension has length = -1.
Immutable if setImmutable() was called, except for an Unlimited Dimension, whose size can change. @author caron
