Syntaxes

This class defines these predicates that act on the objects of this class. In addition, objects of this class can access the predicates defined by the base class AstNodeProperties. An object of this class is an object of AstNodeProperties class.

Predicates	Description
`is(required LinkageSpecification &linkageSpec)`	Finds syntax nodes of the type `LinkageSpecification` and returns them as `linkageSpec`. This represents an `extern "C"` or `extern "C++"` linkage specification.
`isa(Cpp.Node.Node node)`	Checks if `node` is a `LinkageSpecification`.
`cast(Cpp.Node.Node node, required LinkageSpecification &cast)`	Finds `LinkageSpecification` nodes from `node` when compatible.
`value(LinkageSpecification self, Cpp.Node.Node &child)`	Matches the linkage value string literal. For example, this predicate matches `"C"` or `"C++"`.
`body(LinkageSpecification self, Cpp.Node.Node &child)`	Matches the body of a compound linkage specification, such as `{ void foo(); void bar(); }`.
`isEnclosedInLinkageSpecification(Cpp.Node.Node child)`	Checks if `child` appears inside a `LinkageSpecification`.
`getEnclosingLinkageSpecification(Cpp.Node.Node child, required LinkageSpecification &parent)`	Finds the nearest enclosing `LinkageSpecification` ancestor of `child`.
