oAssociativeArray () An associative array (also knows as a map, dictionary or hash table) allows objects to be associated with string keys. The roAssociativeArray class implements the ifAssociativeArray interface. This object is created with no parameters: • CreateObject("roAssociativeArray") The ifAssociativeArray interface provides: • AddReplace(key As String, value As Object) As Void o Add a new entry to the array associating the supplied object with the supplied string. Only one object may be associated with a string so any existing object is discarded. • Lookup(key As String) As Object o Look for an object in the array associated with the specified string. If there is no object associated with the string then an object implementing ifInt containing zero is returned. • DoesExist(key As String) As Boolean o Look for an object in the array associated with the specified string. If there is no associated object then false is returned. If there is such an object then true is returned. • Delete(key As String) As Boolean o Look for an object in the array associated with the specified string. If there is such an object then it is deleted and true is returned. If not then false is returned. • Clear() As Void o Remove all objects from the associative array. Example: aa = CreateObject("roAssociativeArray") aa.AddReplace("Bright", "Sign") aa.AddReplace("TMOL", 42) print aa.Lookup("TMOL") print aa.Lookup("Bright") Produces: 42 Sign 42
oRectangle () This object is created with several parameters: • CreateObject("roRectangle", x As Integer, y As Integer, width As Integer, height As Integer) The interface provides: • SetX(x As Integer) As Void • SetY(y As Integer) As Void • SetWidth(width As Integer) As Void • SetHeight(height As Integer) As Void • GetX() As Integer • GetY() As Integer • GetWidth() As Integer • GetHeight() As Integer SetRectangle calls honor the view mode/aspect ratio conversion mode setup by the user. If the user has set the videoplayer to letterbox the video, it will do so if the video doesn't fit exactly in the new rectangle. 43
