Evaluate Method (Double, Double, Double)

Filter Numeric Rule Evaluator Evaluate(Double, Double, Double) Method

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

Namespace: Autodesk.Revit.DB
Assembly: RevitAPI (in RevitAPI.dll) Version: 25.0.0.0 (25.0.0.0)
Syntax 
public bool Evaluate(
	double lhs,
	double rhs,
	double epsilon
)

Parameters

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

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
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.
