Detailed Description

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.

Member Enumeration Documentation

◆ AmbiguityKind

enum clang::LookupResult::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); // error: A::f and B::f come from subobjects of different
// types. overload resolution is not performed.
}
c
__device__ __2f16 float c
Definition: __clang_hip_libdevice_declares.h:304
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; // error: 'x' is found in two A subobjects (of B and C)
}
D
const Decl * D
Definition: CheckExprLifetime.cpp:200
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; // error 'i' is found in namespace A and A::B
}
}
AmbiguousReferenceToPlaceholderVariable 

Name lookup results in an ambiguity because multiple placeholder variables were found in the same scope.

void f() {
int _ = 0;
int _ = 0;
return _; // ambiguous use of placeholder variable
}
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(); // error: tag 'A::Foo' is hidden by an object in a
// different namespace
}

Definition at line 76 of file Lookup.h.

◆ LookupResultKind

enum clang::LookupResult::LookupResultKind
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.

enum clang::LookupResult::TemporaryToken

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.

◆ isAvailableForLookup()

bool LookupResult::isAvailableForLookup ( Sema &  SemaRef,
NamedDecl *  ND

static

Determine whether this lookup is permitted to see the declaration.

Note that a reachable but not visible declaration inhabiting a namespace is not allowed to be seen during name lookup.

For example:

// m.cppm
export module m;
struct reachable { int v; }
export auto func() { return reachable{43}; }
// Use.cpp
import m;
auto Use() {
// Not valid. We couldn't see reachable here.
// So isAvailableForLookup would return false when we look
up 'reachable' here.
// return reachable(43).v;
// Valid. The field name 'v' is allowed during name lookup.
// So isAvailableForLookup would return true when we look up 'v' here.
return func().v;
}
