Detailed Description

Variant value class.

Basically, a tagged union with value type semantics. It is used by the registry as the return value and argument type for the matcher factory methods. It can be constructed from any of the supported types. It supports copy/assignment.

Supported types:

unsigned
std::string
VariantMatcher (DynTypedMatcher / Matcher<T>)

bool clang::ast_matchers::dynamic::VariantValue::isConvertibleTo	(	ArgKind	Kind,
		unsigned *	Specificity

Determines if the contained value can be converted to Kind.

Parameters:

Kind	the requested destination type.
Specificity	value corresponding to the "specificity" of the convertion.

bool clang::ast_matchers::dynamic::VariantValue::isConvertibleTo	(	ArrayRef< ArgKind >	Kinds,

Determines if the contained value can be converted to any kind in Kinds.

Parameters:

Kinds	the requested destination types.
Specificity	value corresponding to the "specificity" of the convertion. It is the maximum specificity of all the possible conversions.
