ContractCompanion

Metadata and utilities associated with a template as a whole, rather than one single contract made from that template. Application code should not instantiate or subclass; instead, refer to the COMPANION field on generated Template subclasses. All protected members herein are considered part of the INTERNAL API. Every instance is either a ContractCompanion.WithKey or ContractCompanion.WithoutKey, depending on whether the template defined a key type. ContractCompanion.WithKey defines extra utilities for working with contract keys.
