Functions

func NewCommandsResolver

func NewCommandsResolver(commands Commands, commandCompleted func(string)) resolver.Resolver

NewCommandsResolver returns a new Resolver that returns operations to execute "juju run" commands.

The returned resolver's NextOp method will return operations to execute run commands whenever the remote state's "Commands" is non-empty, by taking the first ID in the sequence and fetching the command arguments from the Commands interface passed into this function. When the command execution operation is committed, the ID of the command is passed to the "commandCompleted" callback.

Types

	// with the specified ID, as registered in AddCommand.
	GetCommand(id string) (operation.CommandArgs, operation.CommandResponseFunc)

	// RemoveCommand removes the command arguments and response function
	// associated with the specified ID.
