Detailed Description

Special ErrorInfo subclass representing a list of ErrorInfos.

Instances of this class are constructed by joinError.

Member Function Documentation

◆ convertToErrorCode()

std::error_code llvm::ErrorList::convertToErrorCode ( ) const
overridevirtual

Convert this error to a std::error_code.

This is a temporary crutch to enable interaction with code still using std::error_code. It will be removed in the future.

Implements llvm::ErrorInfoBase.

Definition at line 68 of file Error.cpp.

◆ log()

void llvm::ErrorList::log ( raw_ostream OS) const
inlineoverridevirtual

Print an error message to an output stream.

Implements llvm::ErrorInfoBase.

Definition at line 352 of file Error.h.

References llvm::ErrorInfoBase::convertToErrorCode().

◆ handleErrors

template<typename... HandlerTs>
Error handleErrors ( Error  E,
HandlerTs &&...  Handlers 
)
friend

Pass the ErrorInfo(s) contained in E to their respective handlers.

Any unhandled errors (or Errors returned by handlers) are re-concatenated and returned. Because this function returns an error, its result must also be checked or returned. If you intend to handle all errors use handleAllErrors (which returns void, and will abort() on unhandled errors) instead.

Definition at line 857 of file Error.h.

◆ joinErrors

Error joinErrors ( Error  E1,
Error  E2 
)
friend

Concatenate errors.

The resulting Error is unchecked, and contains the ErrorInfo(s), if any, contained in E1, followed by the ErrorInfo(s), if any, contained in E2.

Definition at line 406 of file Error.h.
