Method Extract
- Namespace

- QueryGuard.Core.dll
Extract(string?)
Extracts every QueryGuard directive from a command's leading comments.
public static IReadOnlyList<string>? Extract(string? commandText)Parameters
Returns
- IReadOnlyList<string>
The directives found, or null when there are none, which is the common case and avoids allocating an empty collection per command.
Remarks
Only line comments are scanned, because that is what TagWith produces. Scanning stops
at the first line that is neither blank nor a comment: a directive belongs at the top of the
statement, and reading the whole statement on every command would be work done for nothing.
