Must copy the unconstrained current values of the proper type within Vector into the local instance.
Implemented in ncml_module::NCMLArray< T >.

pure virtual |
Copy the data values from the given array, assuming the type matches the template type T of the subclass. If not, then exception.

Given the current Shape of the Array, generate the constrained value buffer and set it into the Vector superclass rep for proper serialize().

Get the current dimensions of our superclass Array as a Shape object.

Return whether the constraints used to create Vector._buf for the last read() have changed, meaning we need to recompute Vector._buf using the new values.

If there are no constraints and this is the first call to read(), we will do nothing, assuming the sueprclasses have everything under control.
If there are constraints, this function will create the correct buffer in Vector with the constrained data, generated from cached local values gathered to be from the unconstrained state.
The first call to read() will assume the CURRENT Vector buffer has ALL values (unconstrained) and store a local copy before generating a Vector buffer for the current constraints.
After this call, the caller can be assured that the Vector's data buffer has properly constrained data matching the current super Array's constraints. Subsequent calls to read() will see if the constraints used to create the Vector data buffer have changed and if so recompute a new Vector buffer from the locally cached values.

Override to return false if we have uncomputed constraints and only true if the current constraints match the Vector value buffer.

Override to disable setting of this flag. We will leave it false unless the constraints match the Vector value buffer.
