func (*InputOptions) Name

func (*InputOptions) Name() string

Name returns a human-readable group name for input options.

type MongoFiles

type MongoFiles struct {
	// generic mongo tool options
	ToolOptions *options.ToolOptions

	// mongofiles-specific storage options
	StorageOptions *StorageOptions

	// mongofiles-specific input options
	InputOptions *InputOptions

	// for connecting to the db
	SessionProvider *db.SessionProvider

	// command to run
	Command string

	// filename in GridFS
	FileName string

	// ID to put into GridFS
	Id string

	// List of filenames for use as supporting
	// arguments in put and get commands
	FileNameList []string

	// Regular expression as supporting argument
