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.

◆ getArrayExprIndex()

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

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

◆ getBase()

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

For a base class node, returns the base specifier.

◆ getEndLoc()

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

◆ getField()

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

For a field offsetof node, returns the field.

Definition at line 2433 of file Expr.h.

References Data, Field, and getKind().

Referenced by getFieldName(), clang::tooling::RecursiveSymbolVisitor< T >::VisitOffsetOfExpr(), and clang::ASTNodeImporter::VisitOffsetOfExpr().

◆ getFieldName()

IdentifierInfo * OffsetOfNode::getFieldName ( ) const

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

Definition at line 1692 of file Expr.cpp.

References Field, getField(), clang::NamedDecl::getIdentifier(), getKind(), and Identifier.

◆ 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.
