Detailed Description

An interface for collecting the dependencies of a compilation.

Users should use attachToPreprocessor and attachToASTReader to get all of the dependencies. FIXME: Migrate DependencyFileGen and DependencyGraphGen to use this interface.

◆ maybeAddDependency()

void DependencyCollector::maybeAddDependency ( StringRef  Filename,
bool  FromModule,
bool  IsSystem,
bool  IsModuleFile,
bool  IsMissing 
)

Add a dependency Filename if it has not been seen before and sawDependency() returns true.

Definition at line 118 of file DependencyFile.cpp.

◆ needSystemDependencies()

virtual bool clang::DependencyCollector::needSystemDependencies ( )
inlinevirtual

Return true if system files should be passed to sawDependency().

Definition at line 94 of file Utils.h.

◆ sawDependency()

bool DependencyCollector::sawDependency ( StringRef  Filename,
bool  FromModule,
bool  IsSystem,
bool  IsModuleFile,
bool  IsMissing 
)
virtual

Called when a new file is seen.

Return true if Filename should be added to the list of dependencies.

The default implementation ignores <built-in> and system files.
