Instance Method Details

#register(name, owner) ⇒ Object

Registers owner under name. Returns false when a different live owner already holds the name.

The registry is per-process, so with a multi-process cable adapter the uniqueness check is best-effort (client-generated names carry enough entropy for collisions to be negligible).
