Gang,
I tried to create a general EntityStore Cleaner, which would remove
all entities in the all EntityStores in the current module. To ensure
that Testcases cleanup their crap properly.
It is easy to iterate the EntityStore via
EntityStoreUnitOfWork visitEntityStates( final EntityStateVisitor
visitor, Module moduleInstance );
BUT, since removal will load the entities and a commit can not happen
until after the above method returns, it is not possible to do batches
of let's say 1000 entities, to ensure that memory is not exhausted.
I propose a change to the EntityStateVisitor interface, so that the
EntityStoreUnitOfWork is passed in the method call;
interface EntityStateVisitor
{
void visitEntityState( EntityState entityState,
EntityStoreUnitOfWork esuow );
}
And that this change is propagated equally to the MapEntityStoreVisitor
interface MapEntityStoreVisitor
{
void visitEntity( Reader entityState, EntityStoreUnitOfWork esuow );
}
This allows the visitor to do intermediary commits if needed.
WDYT?
Cheers
