/**
|
|
* A persistent collection.
|
|
*
|
|
* A collection object is strongly typed in the sense that it can only contain
|
|
* entities of a specific type or one of it's subtypes. A collection object is
|
|
* basically a wrapper around an ordinary php array and just like a php array
|
|
* it can have List or Map semantics.
|
|
*
|
|
* A collection of entities represents only the associations (links) to those entities.
|
|
* That means, if the collection is part of a many-many mapping and you remove
|
|
* entities from the collection, only the links in the xref table are removed (on flush).
|
|
* Similarly, if you remove entities from a collection that is part of a one-many
|
|
* mapping this will only result in the nulling out of the foreign keys on flush
|
|
* (or removal of the links in the xref table if the one-many is mapped through an
|
|
* xref table). If you want entities in a one-many collection to be removed when
|
|
* they're removed from the collection, use deleteOrphans => true on the one-many
|
|
* mapping.
