Syntax

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

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

Dim lhs As PIIdentityMapping
Dim rhs As PIIdentityMapping
Dim returnValue As Boolean

returnValue = (lhs < rhs)

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

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

Parameters

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

Return Value

Type: Boolean
Returns if the first operand is less than the second, otherwise.

By definition, any object compares greater than and two null references compare equal to each other.

This method uses the Name of the objects to perform the comparison operation.
