Represents the results of name lookup.

An instance of the LookupResult class captures the results of a single name lookup, which can return no result (nothing found), a single declaration, a set of overloaded functions, or an ambiguity. Use the getKind() method to determine which of these results occurred for a given lookup.

◆ AmbiguityKind

Enumerator
AmbiguousBaseSubobjectTypes Name lookup results in an ambiguity because multiple entities that meet the lookup criteria were found in subobjects of different types. For example: struct A { void f(int); } struct B { void f(double); } struct C : A, B { }; void test(C c) { c.f(0); } c__device__ __2f16 float cDefinition: __clang_hip_libdevice_declares.h:304 clang::LinkageSpecLanguageIDs::C@ C
AmbiguousBaseSubobjects Name lookup results in an ambiguity because multiple nonstatic entities that meet the lookup criteria were found in different subobjects of the same type. For example: struct A { int x; }; struct B : A { }; struct C : A { }; struct D : B, C { }; int test(D d) { return d.x; } Dconst Decl * DDefinition: CheckExprLifetime.cpp:211
AmbiguousReference Name lookup results in an ambiguity because multiple definitions of entity that meet the lookup criteria were found in different declaration contexts. namespace A { int i; namespace B { int i; } int test() { using namespace B; return i; } }
AmbiguousReferenceToPlaceholderVariable Name lookup results in an ambiguity because multiple placeholder variables were found in the same scope. void f() { int _ = 0; int _ = 0; return _; }
AmbiguousTagHiding Name lookup results in an ambiguity because an entity with a tag name was hidden by an entity with an ordinary name from a different context. namespace A { struct Foo {}; } namespace B { void Foo(); } namespace C { using namespace A; using namespace B; } void test() { C::Foo(); }

Enumerator
NotFound No entity found met the criteria.
NotFoundInCurrentInstantiation No entity found met the criteria within the current instantiation,, but there were dependent base classes of the current instantiation that could not be searched.
Found Name lookup found a single declaration that met the criteria. getFoundDecl() will return this declaration.
FoundOverloaded Name lookup found a set of overloaded functions that met the criteria.
FoundUnresolvedValue Name lookup found an unresolvable value declaration and cannot yet complete. This only happens in C++ dependent contexts with dependent using declarations.
Ambiguous Name lookup results in an ambiguity; use getAmbiguityKind to figure out what kind of ambiguity we have.

Returns the 'naming class' for this lookup, i.e.

the class which was looked into to find these results.

C++0x [class.access.base]p5: The access to a member is affected by the class in which the member is named. This naming class is the class in which the member name was looked up and found. [Note: this class can be explicit, e.g., when a qualified-id is used, or implicit, e.g., when a class member access operator (5.2.5) is used (including cases where an implicit "this->" is added). If both a class member access operator and a qualified-id are used to name the member (as in p->T::m), the class naming the member is the class named by the nested-name-specifier of the qualified-id (that is, T). – end note ]

This is set by the lookup routines when they find results in a class.

◆ setTemplateNameLookup()

void clang::LookupResult::setTemplateNameLookup ( bool TemplateName) inline

Sets whether this is a template-name lookup.

For template-name lookups, injected-class-names are treated as naming a template rather than a template specialization.

◆ suppressDiagnostics()

void clang::LookupResult::suppressDiagnostics ( ) inline

Suppress the diagnostics that would normally fire because of this lookup.

This happens during (e.g.) redeclaration lookups.
