Special ErrorInfo subclass representing a list of ErrorInfos.

Instances of this class are constructed by joinError.

◆ 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 93 of file Error.cpp.

◆ log()

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

◆ 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 967 of file Error.h.

◆ joinErrors

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 442 of file Error.h.

◆ visitErrors

template

Visit all the ErrorInfo(s) contained in E by passing them to the respective handler, without consuming the error.

Definition at line 1002 of file Error.h.

◆ ID

char llvm::ErrorList::ID = 0	static
