Member Function Documentation

cloneImpl()

template<typename HasherT>

IntrusiveRefCntPtr< OutputBackend > llvm::vfs::HashingOutputBackend< HasherT >::cloneImpl ( ) const

inlineoverrideprotectedvirtual

Must be thread-safe.

Virtual function has a different name than clone() so that implementations can override the return value.

Implements llvm::vfs::OutputBackend.

Definition at line 71 of file HashingOutputBackend.h.

createFileImpl()

template<typename HasherT>

Expected< std::unique_ptr< OutputFileImpl > > llvm::vfs::HashingOutputBackend< HasherT >::createFileImpl ( StringRef Path, std::optional< OutputConfig > Config )

inlineoverrideprotectedvirtual

Create a file for Path.

Must be thread-safe.

Precondition

Config is valid or std::nullopt.

Implements llvm::vfs::OutputBackend.

Definition at line 76 of file HashingOutputBackend.h.

getHashValueForFile()

template<typename HasherT>

std::optional< std::string > llvm::vfs::HashingOutputBackend< HasherT >::getHashValueForFile ( StringRef Path )

inline

Get hash value for the output files in hex representation.

Return None if the requested path is not generated.

Not thread safe. Should be queried after all outputs are written.

Definition at line 90 of file HashingOutputBackend.h.

References F, and llvm::toHex().

outputFiles()

template<typename HasherT>

auto llvm::vfs::HashingOutputBackend< HasherT >::outputFiles ( ) const

inline

Iterator for all the output file names.

Not thread safe. Should be queried after all outputs are written.

Definition at line 84 of file HashingOutputBackend.h.
