Detailed Description

Every ClangTidyCheck reports errors through a DiagnosticsEngine provided by this context.

A ClangTidyCheck always has access to the active context to report warnings like:

Context->Diag(Loc, "Single-argument constructors must be explicit")

<< FixItHint::CreateInsertion(Loc, "explicit ");

		const Diagnostic &	Info,

		bool	AllowIO = true,
		bool	EnableNoLintBlocks = true )

Check whether a given diagnostic should be suppressed due to the presence of a "NOLINT" suppression comment.

This is exposed so that other tools that present clang-tidy diagnostics (such as clangd) can respect the same suppression rules as clang-tidy. This does not handle suppression of notes following a suppressed diagnostic; that is left to the caller as it requires maintaining state in between calls to this function. If any NOLINT is malformed, e.g. a BEGIN without a subsequent END, output

Parameters

NoLintErrors	will return an error about it. If
AllowIO	is false, the function does not attempt to read source files from disk which are not already mapped into memory; such files are treated as not containing a suppression comment.
EnableNoLintBlocks	controls whether to honor NOLINTBEGIN/NOLINTEND blocks; if false, only considers line-level disabling.

◆ treatAsError()
