The less than relation operator (<) compares its operands to determine which one is less than the other.

Namespace: OSIsoft.AF.Time
Assembly: OSIsoft.AFSDK (in OSIsoft.AFSDK.dll) Version: 3.1.1.1182

Syntax

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

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

Dim lhs As AFTime
Dim rhs As AFTime
Dim returnValue As Boolean

returnValue = (lhs < rhs)

public:
static bool operator <(
	AFTime lhs, 
	AFTime rhs
)

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

Parameters

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

Return Value

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

Remarks

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

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