QueryInterceptor class abstract

An interceptor for SQL queries.

This wraps an existing QueryExecutor implemented by drift, and by default does nothing. However, specific methods can be overridden to customize the behavior of an existing query executor.

To apply an interceptor to an executor, use ApplyInterceptor.interceptWith. This returns a new QueryExecutor which can be used as a replacement when opening the database.

For an example on how interceptors may be used and installed, see this documentation page: https://drift.simonbinder.eu/docs/examples/tracing/
