public class ElementSlowFilter : ElementFilter

The ElementSlowFilter type exposes the following members.

Properties

	Name	Description
	Inverted	True if the results of the filter are inverted; elements that would normally be accepted by this filter will be rejected, and elements that would normally be rejected will be accepted. (Inherited from ElementFilter)
	IsValidObject	Specifies whether the .NET object represents a valid Revit entity. (Inherited from ElementFilter)

Methods

	Name	Description
	Dispose	(Inherited from ElementFilter)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
	GetHashCode	Serves as the default hash function. (Inherited from Object)
	GetType	Gets the Type of the current instance. (Inherited from Object)
	PassesFilter(Element)	Applies the filter to a given element. (Inherited from ElementFilter)
	PassesFilter(Document, ElementId)	Applies the filter to a given element. (Inherited from ElementFilter)
	ToString	Returns a string that represents the current object. (Inherited from Object)

Remarks

Slow filters require that the Element be obtained and expanded in memory first. Thus it is preferable to couple slow filters with at least one ElementQuickFilter, which should minimize the number of Elements that are expanded in order to evaluate against the criteria set by this filter.
