Member Enumeration Documentation

Kind

enum clang::OffsetOfNode::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.

References getKind(), and Identifier.

Referenced by PrintFloatingLiteral(), and clang::ASTNodeImporter::VisitOffsetOfExpr().

getKind()

Kind clang::OffsetOfNode::getKind ( ) const

inline

Determine what kind of offsetof node this is.

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.
