Syntax

C#

public class FilterElementIdRule : FilterNumericValueRule

The FilterElementIdRule type exposes the following members.

Constructors

	Name	Description
	FilterElementIdRule	Constructs an instance of FilterElementIdRule.

Properties

	Name	Description
	IsValidObject	Specifies whether the .NET object represents a valid Revit entity. (Inherited from FilterRule)
	RuleValue	The user-supplied value against which values from a Revit document will be tested.

Methods

	Name	Description
	Dispose	(Inherited from FilterRule)
	ElementPasses	Derived classes override this method to implement the test that determines whether the given element passes this rule or not. (Inherited from FilterRule)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
	GetEvaluator	Gets the evaluator that implements the test for this rule. (Inherited from FilterNumericValueRule)
	GetHashCode	Serves as the default hash function. (Inherited from Object)
	GetRuleParameter	Returns the ElementId of the parameter associated to this FilterRule if there is one, or invalidElementId if there is no associated parameter. (Inherited from FilterRule)
	GetType	Gets the Type of the current instance. (Inherited from Object)
	SetEvaluator	Sets the evaluator that implements the test for this rule. (Inherited from FilterNumericValueRule)
	ToString	Returns a string that represents the current object. (Inherited from Object)
	UsesLevelFiltering	This function checks if a parameter uses level filtering.

Remarks

When GetRuleParameter() returns a parameter that UsesLevelFiltering(Document, ElementId), then the comparisons will first compare the values of the levels' elevations, then compare the levels' names, and finally the levels' element ids to rank and sort the levels.
