public interface EngineCollection
extends java.io.Serializable
```
Provides functionality common to all collection objects. This interface is the base interface for the collection class hierarchy.
A collection can be one of three types: a set, a list, or a row set. A set is a collection of independent objects, the elements of which are unordered and unique. Functionality common only to sets is defined in the EngineSet interface. Sets can be iterated a page at a time (instead of one object or one row at a time), and may not be directly updated. A list is a collection of dependent objects, the elements of which are ordered and need not be unique. A row set is a collection of rows (such as the result set returned from a query) and has the characteristics of a set-type collection.

The name of a collection identifies its type. For example, a DocumentSet is a collection of Document objects, which are independent objects. A DependentObjectList is a collection of dependent objects. A RepositoryRowSet is a row set.

This interface provides standard collection methods.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method and Description
`boolean`	`isEmpty()` Indicates whether the collection is empty.
`java.util.Iterator`	`iterator()` Returns a Java `Iterator` object for iterating the items in the collection.

- Method Detail
  - isEmpty
```
boolean isEmpty()
```
    Indicates whether the collection is empty. This method may require a round trip to the server for unevaluated sets (such as IndependentObjectSet and RepositoryRowSet).
    
    Returns:
    
    true if the collection has no elements; otherwise, returns false.
  - iterator
```
java.util.Iterator iterator()
```
    Returns a Java Iterator object for iterating the items in the collection. In the case of sets, paging is performed transparently.
    The returned Iterator object's remove() method throws an UnsupportedOperationException.
    
    Returns:
    
    An Iterator object.
