SessionResolver

@groovy.transform.CompileStatic
class TransactionSynchronizationSessionResolver
extends java.lang.Object
implements SessionResolver

The default SessionResolver, backed by the same SessionHolder/ TransactionSynchronizationManager state as DatastoreUtils's session binding - a thin, stateless view over the one authoritative session stack for its owning datastore, rather than an independent thread-local store that could disagree with it. Nested bindings are supported because SessionHolder itself is a stack: bind(Session) pushes, resolve() returns the topmost still-connected session, and unbind() closes and pops only the top session, restoring the outer binding rather than discarding the whole holder.

resolve() performs the same housekeeping as DatastoreUtils.doGetSession: disconnected sessions are evicted from the holder, and a holder left empty by eviction is unbound (unless it is synchronized with an active transaction, in which case the transaction manager owns its lifecycle) so that a stale binding can never block a later bindSession.
