Detailed Description

DeclarationNameExtra is used as a base of various uncommon special names.

This class is needed since DeclarationName has not enough space to store the kind of every possible names. Therefore the kind of common names is stored directly in DeclarationName, and the kind of uncommon names is stored in DeclarationNameExtra. It is aligned to 8 bytes because DeclarationName needs the lower 3 bits to store the kind of common names. DeclarationNameExtra is tightly coupled to DeclarationName and any change here is very likely to require changes in DeclarationName(Table).

The kind of "extra" information stored in the DeclarationName.

See ExtraKindOrNumArgs for an explanation of how these enumerator values are used. Note that DeclarationName depends on the numerical values of the enumerators in this enum. See DeclarationName::StoredNameKind for more info.

Member Data Documentation

ExtraKindOrNumArgs

unsigned clang::detail::DeclarationNameExtra::ExtraKindOrNumArgs

protected

ExtraKindOrNumArgs has one of the following meaning:

• The kind of an uncommon C++ special name. This DeclarationNameExtra is in this case in fact either a CXXDeductionGuideNameExtra or a CXXLiteralOperatorIdName.
• It may be also name common to C++ using-directives (CXXUsingDirective),
• Otherwise it is ObjCMultiArgSelector+NumArgs, where NumArgs is the number of arguments in the Objective-C selector, in which case the DeclarationNameExtra is also a MultiKeywordSelector.
