    • calcAverageDegree

      public static double calcAverageDegree​(java.util.HashMap<java.lang.Character,​java.lang.String[]> keys)
      Calculates the average "degree" of a keyboard or keypad. On the qwerty keyboard, 'g' has degree 6, being adjacent to 'ftyhbv' and '\' has degree 1.
      Parameters:
      keys - a keyboard or keypad
      Returns:
      the average degree for this keyboard or keypad

    • neighborsNumber

      public static int neighborsNumber​(java.lang.String[] neighbors)
      Count how many neighbors a key has
      Parameters:
      neighbors - the neighbors
      Returns:
      the number of neighbors

    • getNeighbors

      public static java.util.Set<java.lang.Character> getNeighbors​(AdjacencyGraph adjacencyGraph, java.lang.Character key)
      Returns a set of neighbors for a specific character.
      Parameters:
      adjacencyGraph - the graph you are using to get the neighbors.
      key - the character you are getting neighbors for.
      Returns:
      A set of characters which are neighbors to the passed in character.

    • getTurns

      public static int getTurns​(AdjacencyGraph adjacencyGraph, java.lang.String part)
      Returns the number of turns in the part passed in based on the adjacency graph.
      Parameters:
      adjacencyGraph - the graph you are using to get the neighbors.
      part - the string you are getting turns for.
      Returns:
      the number of turns in this string for the AdjacencyGraph

    • getShifts

      public static int getShifts​(AdjacencyGraph adjacencyGraph, java.lang.String part)
      Returns the number of shifts in case in the part passed in.
      Parameters:
      adjacencyGraph - the graph you are using to get the neighbors
      part - the string you are getting shifts for.
      Returns:
      the number of shifts in this string for the AdjacencyGraph
