Class LongArray

java.lang.Object
  com.esri.arcgis.system.LongArray

All Implemented Interfaces:

com.esri.arcgis.interop.RemoteObjRef, ILongArray, IPersist, IPersistStream, IXMLSerialize, Externalizable, Serializable

public class LongArray
extends Object
implements com.esri.arcgis.interop.RemoteObjRef, ILongArray, IXMLSerialize, IPersist, IPersistStream, Externalizable

An object for holding a Long array.

Description

A LongArray stores an array of long integer values. You can insert or remove elements from any position in the array and access any element via a zero-based index. You can also persist the array to XML.

Remarks

LongArray objects are used by several interfaces including IMapServer to define a list of layer IDs.
