class BindingDecl

Declaration

class BindingDecl : public ValueDecl { /* full declaration omitted */ };

Description

A binding in a decomposition declaration. For instance, given: int n[3]; auto & [a, b, c] = n; a, b, and c are BindingDecls, whose bindings are the expressions x[0], x[1], and x[2] respectively, where x is the implicit DecompositionDecl of type 'int ( & )[3]'.

Member Variables

private clang::ValueDecl* Decomp

The declaration that this binding binds to part of.

private clang::Expr* Binding = nullptr

The binding represented by this declaration. References to this declaration are effectively equivalent to this expression (except that it is only evaluated once at the point of declaration of the binding).

Methods

¶BindingDecl(clang::DeclContext* DC,
            clang::SourceLocation IdLoc,
            clang::IdentifierInfo* Id)

Declared at: clang/include/clang/AST/DeclCXX.h:4001

Parameters

clang::DeclContext* DC

clang::SourceLocation IdLoc

clang::IdentifierInfo* Id

¶static clang::BindingDecl* Create(
    clang::ASTContext& C,
    clang::DeclContext* DC,
    clang::SourceLocation IdLoc,
    clang::IdentifierInfo* Id)

Declared at: clang/include/clang/AST/DeclCXX.h:4009

Parameters

clang::ASTContext& C

clang::DeclContext* DC

clang::SourceLocation IdLoc

clang::IdentifierInfo* Id

¶static clang::BindingDecl* CreateDeserialized(
    clang::ASTContext& C,
    unsigned int ID)

Declared at: clang/include/clang/AST/DeclCXX.h:4011

Parameters

clang::ASTContext& C

unsigned int ID

¶void anchor()

Declared at: clang/include/clang/AST/DeclCXX.h:4004

¶static bool classof(const clang::Decl* D)

Declared at: clang/include/clang/AST/DeclCXX.h:4037

Parameters

const clang::Decl* D

¶static bool classofKind(clang::Decl::Kind K)

Declared at: clang/include/clang/AST/DeclCXX.h:4038

Parameters

clang::Decl::Kind K

¶clang::Expr* getBinding() const

Description

Get the expression to which this declaration is bound. This may be null in two different cases: while parsing the initializer for the decomposition declaration, and when the initializer is type-dependent.

Declared at: clang/include/clang/AST/DeclCXX.h:4016

¶clang::ValueDecl* getDecomposedDecl() const

Description

Get the decomposition declaration that this binding represents a decomposition of.

Declared at: clang/include/clang/AST/DeclCXX.h:4020

¶clang::VarDecl* getHoldingVar() const

Description

Get the variable (if any) that holds the value of evaluating the binding. Only present for user-defined bindings for tuple-like types.

Declared at: clang/include/clang/AST/DeclCXX.h:4024

¶void setBinding(clang::QualType DeclaredType,
                clang::Expr* Binding)

Description

Set the binding for this BindingDecl, along with its declared type (which should be a possibly-cv-qualified form of the type of the binding, or a reference to such a type).

Declared at: clang/include/clang/AST/DeclCXX.h:4029

Parameters

clang::QualType DeclaredType

clang::Expr* Binding

¶void setDecomposedDecl(
    clang::ValueDecl* Decomposed)

Description

Set the decomposed variable for this BindingDecl.

Declared at: clang/include/clang/AST/DeclCXX.h:4035

Parameters

clang::ValueDecl* Decomposed
