Method remove

structure/set.go:355–371

remove is a method on the FSet struct that takes in a variable number of string parameters. It takes these strings to be "members", and generates errors if any of these strings are not currently present in the FSet. Parameters: member: a variable list of strings that are supposed to be "members"

(member ...string)

//	the function immediately returns an ErrInvalidArgs error,
//	which signifies that an invalid argument has been provided to the function.
func (s *FSets) remove(member ...string) error {
	if s == nil {
		return ErrSetNotInitialized
	}
	for _, m := range member {
		// check to see if all members exist
		if _, exists := (*s)[m]; !exists {
			return ErrMemberNotFound
		}
	}
	// iterate again
	for _, m := range member {
		// remove elements from FSets
		delete(*s, m)
	}
	return nil
}

// GetSetFromDB retrieves a set from database given a key. If createIfNotExist is true,
// a new set will be created if the key is not found. It returns the file sets and any write error encountered.
