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

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

Syntax

public static bool operator <=(
	PIPoint lhs,
	PIPoint rhs
)

Public Shared Operator <= ( 
	lhs As PIPoint,
	rhs As PIPoint
) As Boolean

Dim lhs As PIPoint
Dim rhs As PIPoint
Dim returnValue As Boolean

returnValue = (lhs <= rhs)

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

static let inline (<=)
        lhs : PIPoint * 
        rhs : PIPoint  : bool

Parameters

lhs: Type: OSIsoft.AF.PIPIPoint
Left hand operator.
rhs: Type: OSIsoft.AF.PIPIPoint
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 ID and Server of the objects to perform the comparison operation.
