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.

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).

◆ dump()

LLVM_DUMP_METHOD void StandardConversionSequence::dump ( ) const

◆ getFromType()

QualType clang::StandardConversionSequence::getFromType ( ) const inline

◆ getNarrowingKind()

Check if this standard conversion sequence represents a narrowing conversion, according to C++11 [dcl.init.list]p7.

Parameters

Ctx The AST context.
Converted The result of applying this standard conversion sequence.
ConstantValue If this is an NK_Constant_Narrowing conversion, the value of the expression prior to the narrowing conversion.
ConstantType If this is an NK_Constant_Narrowing conversion, the type of the expression prior to the narrowing conversion.
IgnoreFloatToIntegralConversion If true type-narrowing conversions from floating point types to integral types should be ignored.
