Filter String Rule Evaluator Evaluate Method

Derived classes override this method to implement the test that determines whether the two given string 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

C++

public bool Evaluate(
	string lhs,
	string rhs,
	bool caseSensitive
)

Public Function Evaluate ( 
	lhs As String,
	rhs As String,
	caseSensitive As Boolean
) As Boolean

public:
bool Evaluate(
	String^ lhs, 
	String^ rhs, 
	bool caseSensitive
)

member Evaluate : 
        lhs : string * 
        rhs : string * 
        caseSensitive : bool -> bool

Parameters

lhs String: A value from an element in the document.
rhs String: The user-supplied value against which values from the document are tested.
caseSensitive Boolean: If true, string comparisons are done case-sensitively.

Return Value

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

Exceptions

Exception	Condition
ArgumentNullException	A non-optional argument was null

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.
