-// This class exposes a static method that receives a vector of TitleInfo |
-// objects so that it can find the length of the common prefixes among all |
-// the titles. It can be used for tab titles for example so that the common |
-// prefixes can be elided. |
-// First, the caller needs to fill a vector of TitleInfo objects with the titles |
-// for which they want to find the common prefix lengths. They can also provide |
-// an optional caller_value where the index of the tabs could be saved |
-// for example. This way the caller can remember which tab this title belongs |
-// to, if not all tabs are passed into the vector. |
-// When CalculatePrefixLengths returns, the TitleInfo objects in the vector |
-// are set with the prefix_length that is common between this title |
-// and at least one other. |
-// Note that the prefix_length is only calculated at word boundaries. |
