    • encodeEntry

      public static void encodeEntry(Appendable out, int id, int lastId, int reps) throws IOException
      The source map line map is consists of a series of entries each representing a map entry and a repetition count of that entry.
      Parameters:
      out - The entry destination.
      id - The id for the entry.
      lastId - The previous id written, used to generate a relative map id.
      reps - The number of times the id is repeated in the map.
      Throws:
      IOException

    • getRelativeMappingId

      public static int getRelativeMappingId(int id, int idLength, int lastId)
      Parameters:
      idLength - the length relative id, when encoded in as a base64 value. @see #getRelativeMappingIdLength
      Returns:
      A value relative to the the lastId. Negative value are represented as a two-complement value.

    • getRelativeMappingIdLength

      public static int getRelativeMappingIdLength(int rawId, int lastId)
      Returns:
      The length of the base64 number needed to include the id.
