Namespace: Autodesk.Revit.DB Class: FilterNumericRuleEvaluator

FilterNumericRuleEvaluator.Evaluate(Double, Double, Double)

Method

Description:
Derived classes override this method to implement the test that determines whether the two given double-precision values satisfy the desired condition or not.

Remarks:
The arguments may be thought of as the left and right operands of a binary expression; for example, "a < b", "x >= 100", etc. The left operand comes from an element in the Revit document (e.g., the value of a parameter.) The right operand is supplied by the user when creating the filter that contains the rule that uses this evaluator.

Syntax

public bool Evaluate(
	double lhs,
	double rhs,
	double epsilon
)

Public Function Evaluate ( 
	lhs As Double,
	rhs As Double,
	epsilon As Double
) As Boolean

public:
bool Evaluate(
	double lhs, 
	double rhs, 
	double epsilon
)

member Evaluate : 
        lhs : float * 
        rhs : float * 
        epsilon : float -> bool

Parameters

Parameter	Type	Description
lhs	Double	A value from an element in the document.
rhs	Double	The user-supplied value against which values from the document are tested.
epsilon	Double	Defines the tolerance within which two values may be considered equal.

Return Value

Type	Description
Boolean	True if the given arguments satisfy the condition, otherwise false.

Exceptions

Exception	Condition
ArgumentException	The given value for lhs is not finite -or- The given value for lhs is not a number -or- The given value for rhs is not finite -or- The given value for rhs is not a number -or- The given value for epsilon is not finite -or- The given value for epsilon is not a number
