- Method Detail
  - clearDeferredChanges
```
void clearDeferredChanges()
```
    INTERNAL: clear any changes that have been deferred to instantiation. Indirect collections with change tracking avoid instantiation on add/remove.
  - hasDeferredChanges
```
boolean hasDeferredChanges()
```
    INTERNAL: Return if the collection has any changes that have been deferred to instantiation. Indirect collections with change tracking avoid instantiation on add/remove.
  - getAddedElements
```
java.util.Collection getAddedElements()
```
    INTERNAL: Return if the collection has any elements added that have been deferred to instantiation. Indirect collections with change tracking avoid instantiation on add/remove.
  - getRemovedElements
```
java.util.Collection getRemovedElements()
```
    INTERNAL: Return if the collection has any elements removed that have been deferred to instantiation. Indirect collections with change tracking avoid instantiation on add/remove.
  - getDelegateObject
```
java.lang.Object getDelegateObject()
```
    INTERNAL: Return the real collection object. This will force instantiation.
  - setUseLazyInstantiation
```
void setUseLazyInstantiation(boolean useLazyInstantiation)
```
    INTERNAL Set whether this collection should attempt do deal with adds and removes without retrieving the collection from the dB
