Namespace: OSIsoft.AF.PI
Assembly: OSIsoft.AFSDK (in OSIsoft.AFSDK.dll) Version: 3.2.0.7

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.

Return Value

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

Remarks

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.
