public class FamilySymbolFilter : ElementQuickFilter

The FamilySymbolFilter type exposes the following members.

Constructors

	Name	Description
	FamilySymbolFilter	Constructs a new instance of a filter to find all family symbols of the given family.

Properties

	Name	Description
	FamilyId	The family id.
	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

This filter is a quick filter. Quick filters operate only on the ElementRecord, a low-memory class which has a limited interface to read element properties. Elements which are rejected by a quick filter will not be expanded in memory.

Note that it may be faster to get a list of symbol ids from GetFamilySymbolIds() rather than to iterate all of the contents of a document with this filter applied.
