Collects all bindings in Cluster
that may refer to bindings within Top
.
Each binding is a pair whose first
is the key (a BindingKey) and whose second
is the value (an SVal).
The IncludeAllDefaultBindings
parameter specifies whether to include default bindings that may extend beyond Top
itself, e.g. if Top
is an aggregate within a larger aggregate with a default binding.

Checks to see if store B
has a lazy binding for region R
.
If AllowSubregionBindings
is false
, a lazy binding will be rejected if there are additional bindings within R
.
Note that unlike RegionStoreManager::findLazyBinding, this will not search for lazy bindings for super-regions of R
.
