Returns:
- Type
- Buffer
getRawQueryOptions() → {QueryOptions}
Gets the query options as provided to the execution method without setting the default values.
- Source:
Returns:
- Type
- QueryOptions
(abstract) getReadTimeout() → {Number}

- Number
(abstract) getRetryPolicy() → {RetryPolicy}
Gets the retry policy to be used.
- Source:
Returns:
A RetryPolicy instance, it can't be undefined.
- Type
- RetryPolicy
