Android Question Public Property

[/
        Public Property Longitude() As Coordinate
            Get
                Return cooLong
            End Get
            Set(value As Coordinate)
                If value.Direction = CardinalDirection.East OrElse value.Direction = CardinalDirection.West Then
                    cooLong = value
                    GetUTM()
                End If
            End Set
        End Property
]

How would I write this in B4A?

Thanks
