Instance Method Details

#template(*argv) { ... } ⇒ CAUnboundRepeat

Overrides CArray#template for unbound-repeat views.

The C-level CArray#template allocates an entity sized to self.shape, which for a CAUnboundRepeat would include the inflated unbound (:*) axes — semantically wrong (unbound axes are not yet bound to a size) and a memory bomb on broadcast patterns. Required for correctness.

This override allocates at the parent's compact shape instead, then rewraps the result with the same spec so the returned view preserves the unbound broadcast pattern.

Parameters:

  • argv (Array) —

    forwarded to CArray#template (data_type, bytes:, ...)

Yields:

  • forwarded to CArray#template

Returns:
