Syntax

C# 
public static ParameterFilterElement Create(
	Document aDocument,
	string name,
	ICollection<ElementId> categories,
	ElementFilter elementFilter
)
Visual Basic 
Public Shared Function Create ( _
	aDocument As Document, _
	name As String, _
	categories As ICollection(Of ElementId), _
	elementFilter As ElementFilter _
) As ParameterFilterElement
Visual C++ 
public:
static ParameterFilterElement^ Create(
	Document^ aDocument, 
	String^ name, 
	ICollection<ElementId^>^ categories, 
	ElementFilter^ elementFilter
)

Parameters

aDocument
Type: Autodesk.Revit.DB Document
The document in which to create the ParameterFilterElement.
name
Type: System String
The user-visible name for the new ParameterFilterElement.
categories
Type: System.Collections.Generic ICollection ElementId
The categories for the new ParameterFilterElement.
elementFilter
Type: Autodesk.Revit.DB ElementFilter
The rules for the new ParameterFilterElement, represented as an ElementFilter. ElementFilter is either an ElementParameterFilter or an ElementLogicalFilter representing a Boolean combination of ElementParameterFilters. In addition, we check that each ElementParameterFilter satisfies the following conditions: Its array of FilterRules is not empty and contains:
  • Any number of FilterRules of type FilterValueRule, FilterInverseRule, and SharedParameterApplicableRule or
  • Exactly one FilterCategoryRule containing only one category from categories stored by this ParameterFilterElement or
  • Exactly two rules: the first one is a FilterCategoryRule containing only one category from categories stored by this ParameterFilterElement and the second one is a FilterRule of type FilterValueRule, FilterInverseRule, or SharedParameterApplicableRule.
Note that cases in the second and third bullet are currently allowed only if the parent node of ElementParameterFilter is LogicalOrFilter.

Return Value

A pointer to the new ParameterFilterElement.
