Interfaces

Name	Description
IJBController	General interface for the generic controller methods in this contract that interacts with funding cycles and tokens according to the protocol's rules.
IJBMigratable	Allows migrating to this contract, with a hook called to prepare for the migration.

Inheritance

Contract	Description
JBOperatable	Includes convenience functionality for checking a message sender's permissions before executing certain transactions.
ERC165	Introspection on interface adherance.
