def _empty_of_local_shape(self, context, dtype): (source)

Create an empty array whose shape matches its environment. This kind of behavior is necessary because we allow new bindings to be created through masking adapters and need to create a shape for the real, unmasked array. The current behavior is to assume a 'depth' array exists and to use its shape. FIXME
