Syntax

public static bool operator <(
	PIPointClass lhs,
	PIPointClass rhs
)

Public Shared Operator < ( 
	lhs As PIPointClass,
	rhs As PIPointClass
) As Boolean

Dim lhs As PIPointClass
Dim rhs As PIPointClass
Dim returnValue As Boolean

returnValue = (lhs < rhs)

public:
static bool operator <(
	PIPointClass^ lhs, 
	PIPointClass^ rhs
)

static let inline (<)
        lhs : PIPointClass * 
        rhs : PIPointClass  : bool

Parameters

lhs: Type: OSIsoft.AF.PIPIPointClass
Left hand operator.
rhs: Type: OSIsoft.AF.PIPIPointClass
Right hand operator.
