class ModuleDepCollector

Declaration

class ModuleDepCollector : public DependencyCollector { /* full declaration omitted */ };

Description

Collects modular and non-modular dependencies of the main file by attaching\c ModuleDepCollectorPP to the preprocessor.

Declared at: clang/include/clang/Tooling/DependencyScanning/ModuleDepCollector.h:199

Inherits from: DependencyCollector

Member Variables

private clang::CompilerInstance& ScanInstance

The compiler instance for scanning the current translation unit.

private clang::tooling::dependencies::DependencyConsumer& Consumer

The consumer of collected dependency information.

private std::string MainFile

Path to the main source file.

private std::string ContextHash

Hash identifying the compilation conditions of the current TU.

private std::vector<std::string> FileDeps

Non-modular file dependencies. This includes the main source file and textually included header files.

private llvm::MapVector<const Module*, std::unique_ptr<ModuleDeps>> ModularDeps

Direct and transitive modular dependencies of the main source file.

private std::unique_ptr<DependencyOutputOptions> Opts

Options that control the dependency output generation.

private clang::CompilerInvocation OriginalInvocation

The original Clang invocation passed to dependency scanner.

private bool OptimizeArgs

Whether to optimize the modules' command-line arguments.
