Nested Class Summary
static class	Cascades.CascadeStyle           A style of cascade that can be specified by the mapping for an association.
static class	Cascades.CascadingAction           A session action that may be cascaded from parent entity to its children
static class	Cascades.IdentifierValue           A strategy for determining if an identifier value is an identifier of a new transient instance or a previously persistent transient instance.
static class	Cascades.VersionValue           A strategy for determining if a version value is an version of a new transient instance or a previously persistent transient instance.
