Detailed Description

This is a collection of features.

Represents a shallow snapshot of a collection of features. Stores references to the features at the time of creation. If those features change after the collection has been created, the collection still contains the modified features. If a feature within the collection is deleted, the collection still returns a corresponding feature of which its methods always fail with E_INVALID_OR_DELETED_FEATURE.

This collection is compatible with JavaScript, Visual Basic, and VBScript.

Example code in JavaScript:
var featureCollection = ...; // initialize to refer to collection object
var enum = new Enumerator(featureCollection);
for (; !enum.atEnd(); enum.moveNext())
  var feature = e.item();
  doSomething(feature);
}

Example code in Visual Basic and VBScript:
Dim featureCollection = ... ' initialize to refer to collection object
For Each feature In featureCollection
  DoSomething feature
Next

Note:

This is a one-based index collection, which means the first element's index is 1, and the last element's index is equal to the collection's Count.

Associated GUIDs:

• IID_IFeatureCollectionGE = {0x851D25E7,0x785F,0x4DB7, {0x95,0xF9,0xA0,0xEF,0x7E,0x83,0x6C,0x44}};
