ExtObjectSet SourceCode GPL - https://github.com/iboxdb/db4o-gpl

All Superinterfaces:

java.util.Collection, java.lang.Iterable, java.util.List, ObjectSet

All Known Implementing Classes:

ObjectSetFacade
```
public interface ExtObjectSet
extends ObjectSet
```
extended functionality for the ObjectSet interface.

Every db4o ObjectSet always is an ExtObjectSet so a cast is possible.

ObjectSet.ext() is a convenient method to perform the cast.

The ObjectSet functionality is split to two interfaces to allow newcomers to focus on the essential methods.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`java.lang.Object`	`get(int index)`	returns the item at position [index] in this ObjectSet.
`long[]`	`getIDs()`	returns an array of internal IDs that correspond to the contained objects.
`void`	`skip(int count)`	skips the specified number of objects without activating them.

- Method Detail
  - getIDs
```
long[] getIDs()
```
    returns an array of internal IDs that correspond to the contained objects.
    
    See Also:
    
    ExtObjectContainer.getID(java.lang.Object), ExtObjectContainer.getByID(long)
  - get
```
java.lang.Object get(int index)
```
    returns the item at position [index] in this ObjectSet.
    
    The object will be activated.
    
    Specified by:
    
    get in interface java.util.List
    
    Parameters:
    
    index - the index position in this ObjectSet.
    
    Returns:
    
    the activated object.
  - skip
```
void skip(int count)
```
    skips the specified number of objects without activating them. Call this method before starting iterating over the iterator returned by List.iterator(). This method has no effect on calls to get(int)
