Time for action – GamePiece class methods – part 3 – connection methods

1. Add the GetOtherEnds() method to the GamePiece class:

   Public Function GetOtherEnds(startingEnd As String) As String()
     Dim Opposites As List(Of String) = New List(Of String)()
   
       For Each pipeEnd As String In _pieceType.Split(CChar(","))
         If pipeEnd <> startingEnd Then
           Opposites.Add(pipeEnd)
         End If
       Next
   
     Return Opposites.ToArray()
   End Function

2. Add the HasConnector() method to the GamePiece class:

   Public Function HasConnector(direction As String) As Boolean
     Return _pieceType.Contains(direction)
   End Function

What just happened?

The GetOtherEnds() method creates an empty List object for holding the ends we want to return to the calling code. It then uses the Split() method of the String class to get each end listed in the _pieceType. For example, the Top,Bottom piece will return an array with two elements. The first element will contain Top, and the second will contain Bottom. The comma delimiter...
