Detailed Description

Manages a set of available checkers for running a static analysis.

The checkers are organized into packages by full name, where including a package will recursively include all subpackages and checkers within it. For example, the checker "core.builtin.NoReturnFunctionChecker" will be included if initializeManager() is called with an option of "core", "core.builtin", or the full name "core.builtin.NoReturnFunctionChecker".

◆ addChecker() [1/2]

void clang::ento::CheckerRegistry::addChecker	(	RegisterCheckerFn	Fn,
		ShouldRegisterFunction	sfn,
		StringRef	FullName,
		StringRef	Desc,
		StringRef	DocsUri,
		bool	IsHidden
	)

Adds a checker to the registry.

Use this non-templated overload when your checker requires custom initialization.

◆ addChecker() [2/2]

template<class T >

void clang::ento::CheckerRegistry::addChecker	(	StringRef	FullName,
		StringRef	Desc,
		StringRef	DocsUri,
		bool	IsHidden = `false`
	)

inline

Adds a checker to the registry.

Use this templated overload when your checker does not require any custom initialization. This function isn't really needed and probably causes more headaches than the tiny convenience that it provides, but external plugins might use it, and there isn't a strong incentive to remove it.

◆ addCheckerOption()

void CheckerRegistry::addCheckerOption	(	StringRef	OptionType,
		StringRef	CheckerFullName,
		StringRef	OptionName,
		StringRef	DefaultValStr,
		StringRef	Description,
		StringRef	DevelopmentStatus,
		bool	IsHidden = `false`
	)

Registers an option to a given checker.

A checker option will always have the following format: CheckerFullName:OptionName=Value And can be specified from the command line like this: -analyzer-config CheckerFullName:OptionName=Value

Options for unknown checkers, or unknown options for a given checker, or invalid value types for that given option are reported as an error in non-compatibility mode.

◆ addDependency()

void CheckerRegistry::addDependency	(	StringRef	FullName,
		StringRef	Dependency
	)

Makes the checker with the full name fullName depend on the checker called dependency.

void CheckerRegistry::addPackage ( StringRef FullName )

Adds a package to the registry.

		StringRef	PackageFullName,
		StringRef	OptionName,

		bool	IsHidden = `false`
	)

Registers an option to a given package.

A package option will always have the following format: PackageFullName:OptionName=Value And can be specified from the command line like this: -analyzer-config PackageFullName:OptionName=Value

Options for unknown packages, or unknown options for a given package, or invalid value types for that given option are reported as an error in non-compatibility mode.

◆ addWeakDependency()

void CheckerRegistry::addWeakDependency	(	StringRef	FullName,

Makes the checker with the full name fullName weak depend on the checker called dependency.

◆ initializeManager()

void CheckerRegistry::initializeManager ( CheckerManager & CheckerMgr ) const

Initializes a CheckerManager by calling the initialization functions for all checkers specified by the given CheckerOptInfo list.

The order of this list is significant; later options can be used to reverse earlier ones. This can be used to exclude certain checkers in an included package.
