Member Enumeration Documentation

◆ Kind

The kind of offsetof node we have.

Enumerator
Array 

An index into an array.

Field 

A field.

Identifier 

A field in a dependent type, known only by its name.

Base 

An implicit indirection through a C++ base class, when the field found is in a base class.

Constructor & Destructor Documentation

◆ OffsetOfNode() [1/4]

clang::OffsetOfNode::OffsetOfNode ( SourceLocation  LBracketLoc,
unsigned  Index,
SourceLocation  RBracketLoc 
)
inline

Create an offsetof node that refers to an array element.

Definition at line 1856 of file Expr.h.

◆ OffsetOfNode() [2/4]

clang::OffsetOfNode::OffsetOfNode ( SourceLocation  DotLoc,
FieldDecl Field,
SourceLocation  NameLoc 
)
inline

Create an offsetof node that refers to a field.

Definition at line 1861 of file Expr.h.

◆ OffsetOfNode() [3/4]

clang::OffsetOfNode::OffsetOfNode ( SourceLocation  DotLoc,
IdentifierInfo Name,
SourceLocation  NameLoc 
)
inline

Create an offsetof node that refers to an identifier.

Definition at line 1866 of file Expr.h.

◆ OffsetOfNode() [4/4]

clang::OffsetOfNode::OffsetOfNode ( const CXXBaseSpecifier Base)
inlineexplicit

Create an offsetof node that refers into a C++ base class.

Definition at line 1872 of file Expr.h.

Member Function Documentation

◆ getArrayExprIndex()

unsigned clang::OffsetOfNode::getArrayExprIndex ( ) const
inline

For an array element node, returns the index into the array of expressions.

Definition at line 1880 of file Expr.h.

References getKind().

◆ getBase()

CXXBaseSpecifier* clang::OffsetOfNode::getBase ( ) const
inline

For a base class node, returns the base specifier.

Definition at line 1896 of file Expr.h.

References getKind().

◆ getField()

FieldDecl* clang::OffsetOfNode::getField ( ) const
inline

For a field offsetof node, returns the field.

Definition at line 1886 of file Expr.h.

References clang::SubobjectAdjustment::Field, and getKind().

◆ getFieldName()

IdentifierInfo * OffsetOfNode::getFieldName ( ) const

For a field or identifier offsetof node, returns the name of the field.

Definition at line 1391 of file Expr.cpp.

References getKind().

Referenced by PrintFloatingLiteral().

◆ getKind()

Kind clang::OffsetOfNode::getKind ( ) const
inline

Determine what kind of offsetof node this is.

Definition at line 1876 of file Expr.h.

◆ getLocEnd()

SourceLocation clang::OffsetOfNode::getLocEnd ( ) const
inline

Definition at line 1909 of file Expr.h.

References clang::SourceRange::getEnd().

◆ getLocStart()

SourceLocation clang::OffsetOfNode::getLocStart ( ) const

Definition at line 1908 of file Expr.h.

References clang::SourceRange::getBegin().

◆ getSourceRange()

SourceRange clang::OffsetOfNode::getSourceRange ( ) const
inline

Retrieve the source range that covers this offsetof node.

For an array element node, the source range contains the locations of the square brackets. For a field or identifier node, the source range contains the location of the period (if there is one) and the identifier.
