beginExclusive method

@override QueryExecutor beginExclusive()

Returns a new QueryExecutor that, when first opened, takes an exclusive lock over this executor and prevents queries from running until it is closed.

The difference between this and beginTransaction is that this does not start a database transaction. The QueryExecutor returned by beginExclusive can be used to start a transaction with beginTransaction.

Implementation

@override
QueryExecutor beginExclusive() {
  return _ExclusiveExecutor(this);
}
