collection persister

Extract the values of the component properties from the given component instance without access to the
session.
|

an entity, or key of a collection)
|

|
Object |
hydrate(ResultSet rs,
String[] names,
SessionImplementor session,

|
boolean |
isAlwaysDirtyChecked()
Do we dirty check this association, even when there are
no columns to be updated?
|
boolean |
isAnyType()
Return true if the implementation is castable to
AnyType . |
boolean |
isAssociationType()
Return true if the implementation is castable to
AssociationType . |
boolean |

Return true if the implementation is castable to
CompositeType . |

Object current,
boolean[] checkable,
SessionImplementor session)
Should the parent be considered dirty, given both the old and current value?
|
boolean |
isEmbedded()
Is this component embedded? "embedded" indicates that the component is "virtual", that its properties are
"flattened" onto its owner

associations.
