IEnumNetEID Interface

Provides access to members that iterate through an enumeration of network element IDs (EIDs).

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

Members

		Description
	Count	Number of network elements in this enumeration.
	ElementType	Type of network elements in this enumeration.
	Last	Forces the enumerator pointing at the last element in the enumeration and returns the last element.
	Network	Network from which these elements came.
	Next	Moves the enumerator forward and returns the network element pointed by the enumerator.
	Prev	Returns the network element pointed by the enumerator and moves the enumerator backward.
	Reset	Forces the enumerator pointing before first network element; a subsequent next gives the first network element in the enumeration.

CoClasses that implement IEnumNetEID

CoClasses and Classes	Description
EnumNetEIDArray	A container for defining a network element ID (EID) enumeration.

Remarks

The IEnumNetEID interface is returned by various methods on the logical network. It contains a set of EIDs from a given network. For example, calling the method INetwork::CreateNetBrowser returns a reference to the IEnumNetEID interface containing a set of EIDs based on the specified type of network element requested. INetElements::GetEIDs also returns an enumerator of this type.

Many of the trace tasks on the TraceFlowSolver object return this enumerator as well.
