Detailed Description

CaseStmt - Represent a case statement.

It can optionally be a GNU case statement of the form LHS ... RHS representing a range of cases.

Definition at line 1809 of file Stmt.h.

Member Function Documentation

◆ caseStmtIsGNURange()

bool clang::CaseStmt::caseStmtIsGNURange ( ) const

inline

True if this case statement is of the form case LHS ... RHS, which is a GNU extension.

In this case the RHS can be obtained with getRHS() and the location of the ellipsis can be obtained with getEllipsisLoc().
