Detailed Description
Simple callback implementation. Marshaller and function are provided.
This class wraps a function of arbitrary signature and a marshaller function into a MatcherDescriptor. The marshaller is in charge of taking the VariantValue arguments, checking their types, unpacking them and calling the underlying function.

- Parameters:
-
Marshaller Function to unpack the arguments and call FuncFunc Matcher construct function. This is the function that compile-time matcher expressions would use to create the matcher. RetKinds The list of matcher types to which the matcher is convertible. ArgKinds The types of the arguments this matcher takes.

Given that the matcher is being converted to type ThisKind, append the set of argument types accepted for argument ArgNo to ArgKinds.

| unsigned clang::ast_matchers::dynamic::internal::FixedArgCountMatcherDescriptor::getNumArgs | ( | ) | const [inline, virtual] |
Returns the number of arguments accepted by the matcher if not variadic.

| unsigned * | Specificity, | ||
| ast_type_traits::ASTNodeKind * | LeastDerivedKind | ||
| ) | const [inline, virtual] |
Returns whether this matcher is convertible to the given type. If it is so convertible, store in *Specificity a value corresponding to the "specificity" of the converted matcher to the given context, and in LeastDerivedKind the least derived matcher kind which would result in the same matcher overload. Zero specificity indicates that this conversion would produce a trivial matcher that will either always or never match. Such matchers are excluded from code completion results.

| bool clang::ast_matchers::dynamic::internal::FixedArgCountMatcherDescriptor::isVariadic | ( | ) | const [inline, virtual] |
Returns whether the matcher is variadic. Variadic matchers can take any number of arguments, but they must be of the same type.
