class FieldDecl

Declaration

class FieldDecl : public DeclaratorDecl, public Mergeable { /* full declaration omitted */ };

Description

Represents a member of a struct/union/class.

Declared at: clang/include/clang/AST/Decl.h:2873

Inherits from: DeclaratorDecl, Mergeable

Member Variables

private unsigned int BitField

private unsigned int Mutable

private unsigned int CachedFieldIndex

private llvm::PointerIntPair<void*, 2, InitStorageKind> InitStorage

If the storage kind is ISK_InClassCopyInit or ISK_InClassListInit, but the initializer is null, then this field has an in-class initializer that has not yet been parsed and attached.

Parameters

const clang::ASTContext& Ctx

¶const clang::FieldDecl* getCanonicalDecl() const

Declared at: clang/include/clang/AST/Decl.h:3077

¶clang::FieldDecl* getCanonicalDecl()

Description

Retrieves the canonical declaration of this field.

Declared at: clang/include/clang/AST/Decl.h:3076

¶const clang::VariableArrayType*
getCapturedVLAType() const

Description

Get the captured variable length array type.

Declared at: clang/include/clang/AST/Decl.h:3051

¶unsigned int getFieldIndex() const

Description

Returns the index of this field within its record, as appropriate for passing to ASTRecordLayout::getFieldOffset.

Declared at: clang/include/clang/AST/Decl.h:2945

¶clang::InClassInitStyle getInClassInitStyle()
    const

Description

Get the kind of (C++11) default member initializer that this field has.

Declared at: clang/include/clang/AST/Decl.h:3006

¶clang::Expr* getInClassInitializer() const

Description

Get the C++11 default member initializer for this member, or null if one has not been set. If a valid declaration has a default member initializer, but this returns null, then we have not parsed and attached it yet.

Declared at: clang/include/clang/AST/Decl.h:3065

¶clang::RecordDecl* getParent()

Declared at: clang/include/clang/AST/Decl.h:3069

Determine whether this member has a C++11 default member initializer.

Declared at: clang/include/clang/AST/Decl.h:3013
