Public Attributes | |
| ImplicitConversionKind | First: 8 |
| First – The first conversion can be an lvalue-to-rvalue conversion, array-to-pointer conversion, or function-to-pointer conversion. | |
| ImplicitConversionKind | Second: 8 |
| Second - The second conversion can be an integral promotion, floating point promotion, integral conversion, floating point conversion, floating-integral conversion, pointer conversion, pointer-to-member conversion, or boolean conversion. | |
| ImplicitConversionKind | Dimension: 8 |
| Dimension - Between the second and third conversion a vector or matrix dimension conversion may occur. | |
| ImplicitConversionKind | Third: 8 |
| Third - The third conversion can be a qualification conversion or a function conversion. | |
| unsigned | DeprecatedStringLiteralToCharPtr: 1 |
| Whether this is the deprecated conversion of a string literal to a pointer to non-const character data (C++ 4.2p2). | |
| unsigned | QualificationIncludesObjCLifetime: 1 |
| Whether the qualification conversion involves a change in the Objective-C lifetime (for automatic reference counting). | |
| unsigned | IncompatibleObjC: 1 |
| IncompatibleObjC - Whether this is an Objective-C conversion that we should warn about (if we actually use it). | |
| unsigned | ReferenceBinding: 1 |
| ReferenceBinding - True when this is a reference binding (C++ [over.ics.ref]). | |
| unsigned | DirectBinding: 1 |
| DirectBinding - True when this is a reference binding that is a direct binding (C++ [dcl.init.ref]). | |
| unsigned | IsLvalueReference: 1 |
| Whether this is an lvalue reference binding (otherwise, it's an rvalue reference binding). | |
| unsigned | BindsToFunctionLvalue: 1 |
| Whether we're binding to a function lvalue. | |
| unsigned | BindsToRvalue: 1 |
| Whether we're binding to an rvalue. | |
| unsigned | BindsImplicitObjectArgumentWithoutRefQualifier: 1 |
| Whether this binds an implicit object argument to a non-static member function without a ref-qualifier. | |
| unsigned | ObjCLifetimeConversionBinding: 1 |
| Whether this binds a reference to an object with a different Objective-C lifetime qualifier. | |
| void * | FromTypePtr |
| FromType - The type that this conversion is converting from. | |
| void * | ToTypePtrs [3] |
| ToType - The types that this conversion is converting to in each step. | |
| CXXConstructorDecl * | CopyConstructor |
| CopyConstructor - The copy constructor that is used to perform this conversion, when the conversion is actually just the initialization of an object via copy constructor. | |
| DeclAccessPair | FoundCopyConstructor |
StandardConversionSequence - represents a standard conversion sequence (C++ 13.3.3.1.1).
A standard conversion sequence contains between zero and three conversions. If a particular conversion is not needed, it will be set to the identity conversion (ICK_Identity).
Definition at line 292 of file Overload.h.
| LLVM_DUMP_METHOD void StandardConversionSequence::dump | ( | ) | const |
dump - Print this standard conversion sequence to standard error.
Useful for debugging overloading issues.
