Instance Method Details

#tag_version(tag) ⇒ Object

Accepts a single string argument which is attached to the version record associated with the current version number of the parent object.

Returns the given tag if successful, nil if not. Tags must be unique within the scope of the parent object. Tag creation will fail if non-unique.

Version records corresponding to version number 1 are not typically created, but one will be built to house the given tag if the parent object’s current version number is 1.
