class CBNSLink

The Link data structure is used primarily to store the relation between the two nodes

Public Fields

static int	m_nCounter The variable is used to check for the memory leaks in the program
static int	m_nID Is a unique identifier for the link and is used to remove duplicates

Public Methods

virtual void

Copy (CBNSLink& cLink) This function can be used to copy the contents from cLink
