rewriteDescendants(
    const clang::Decl& Node,
    clang::transformer::RewriteRule Rule,
    const ast_matchers::MatchFinder::MatchResult&
        Result)

Description

The following overload set is a version of `rewriteDescendants` that operates directly on the AST, rather than generating a Transformer combinator. It applies `Rule` to all descendants of `Node`, although not `Node` itself. `Rule` can refer to nodes bound in `Result`. For example, assuming that "body" is bound to a function body in MatchResult `Results`, this will produce edits to change all appearances of `x` in that body to `3`. ``` auto InlineX = makeRule(declRefExpr(to(varDecl(hasName("x")))), changeTo(cat("3"))); const auto *Node = Results.Nodes.getNodeAs <Stmt >("body"); auto Edits = rewriteDescendants(*Node, InlineX, Results); ``` @ {
