Detailed Description

This represents a decl that may have a name.

Many decls have names such as ObjCMethodDecl, but not @class, etc.

Note that not every NamedDecl is actually named (e.g., a struct might be anonymous), and not every name is an identifier.

◆ ExplicitVisibilityKind

Kinds of explicit visibility.


Do an LV computation for, ultimately, a type.

Visibility may be restricted by type visibility settings and the visibility of template arguments.


Do an LV computation for, ultimately, a non-type declaration.

◆ declarationReplaces()

bool NamedDecl::declarationReplaces ( NamedDecl OldD,
bool  IsKnownNewer = true 
) const

Determine whether this declaration, if known to be well-formed within its context, will replace the declaration OldD if introduced into scope.

A declaration will replace another declaration if, for example, it is a redeclaration of the same variable or function, but not if it is a declaration of a different kind (function vs. class) or an overloaded function.

IsKnownNewertrue if this declaration is known to be newer than OldD (for instance, if this declaration is newly-created).

◆ getDeclName()

DeclarationName clang::NamedDecl::getDeclName ( ) const

Get the actual, stored name of the declaration, which may be a special name.

Note that generally in diagnostics, the non-null NamedDecl* itself should be sent into the diagnostic instead of using the result of getDeclName().

A DeclarationName in a diagnostic will just be streamed to the output, which will directly result in a call to DeclarationName::print.

A NamedDecl* in a diagnostic will also ultimately result in a call to DeclarationName::print, but with two customisation points along the way (getNameForDiagnostic and printName). These are used to print the template arguments if any, and to provide a user-friendly name for some entities (such as unnamed variables and anonymous records).

This will return NULL if this declaration has no name (e.g., for an unnamed class) or if the name is a special name (C++ constructor, Objective-C selector, etc.).

Appends a human-readable name for this declaration into the given stream.

This is the method invoked by Sema when displaying a NamedDecl in a diagnostic. It does not necessarily produce the same result as printName(); for example, class template specializations are printed with their template arguments.

Creating this name is expensive, so it should be called only when performance doesn't matter.
