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.
| 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.
}
|
| 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: |
| 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
}
}
|
| 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
}
|
| 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.
