Seems like a standard case, as in:
bind(NoSqlEntityManager.class)
.toProvider(new Provider<NoSqlEntityManager>() {
@Override public NoSqlEntityManager get() {
NoSqlMgrFactory factory = NoSqlPersistence.createMgrFactory();
return factory.createMgr();
}
}).in(Singleton.class);
or
@Provides @Singleton provideNoSqlEntityManager() {
NoSqlMgrFactory factory = NoSqlPersistence.createMgrFactory();
return factory.createMgr();
}
