Enumeration Type Documentation

◆ CacheStatFailure

enum class clang::tooling::dependencies::CacheStatFailure

strong

Enumerator
Yes
No

Definition at line 273 of file DependencyScanningFilesystem.h.

◆ ModuleOutputKind

enum class clang::tooling::dependencies::ModuleOutputKind

strong

An output from a module compilation, such as the path of the module file.

Enumerator
ModuleFile	The module file (.pcm). Required.
DependencyFile	The path of the dependency file (.d), if any.
DependencyTargets	The null-separated list of names to use as the targets in the dependency file, if any. Defaults to the value of `ModuleFile`, as in the driver.
DiagnosticSerializationFile	The path of the serialized diagnostic file (.dia), if any.

Definition at line 88 of file ModuleDepCollector.h.

◆ ScanFile

enum class clang::tooling::dependencies::ScanFile

strong

Enumerator
Yes
No

Definition at line 272 of file DependencyScanningFilesystem.h.

◆ ScanningMode

enum class clang::tooling::dependencies::ScanningMode

strong

The mode in which the dependency scanner will operate to find the dependencies.

Enumerator
CanonicalPreprocessing	This mode is used to compute the dependencies by running the preprocessor over the source files.
DependencyDirectivesScan	This mode is used to compute the dependencies by running the preprocessor with special kind of lexing after scanning header and source files to get the minimum necessary preprocessor directives for evaluating includes.
