Parameter
Base class for parameter resolvers, needs to be implemented alongside the interface of at least one interaction type:
Text commands: TextParameterResolver or QuotableTextParameterResolver
Slash commands: SlashParameterResolver
Message context commands: MessageContextParameterResolver
User context commands: UserContextParameterResolver
Components: ComponentParameterResolver
Component timeouts: TimeoutParameterResolver
Modal handlers: ModalParameterResolver
Custom parameter types: ICustomResolver
Usage
As this class is sealed, you need to extend ClassParameterResolver or TypedParameterResolver instead.

The channel types are set automatically depending on the type, but a broader channel type can be used and restricted to multiple concrete types by using @ChannelTypes.
Parameter resolvers for services exist by default, and follow the rules described in @BService.
You can also check loaded parameter resolvers in the logs on the trace level.
