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 OptionalTypeParameterDeclaration &optTypeParamDecl)`	Finds syntax nodes of the type `OptionalTypeParameterDeclaration` and returns them as `optTypeParamDecl`. This represents a template type parameter with a default.
`isa(Cpp.Node.Node node)`	Checks if `node` is an `OptionalTypeParameterDeclaration`.
`cast(Cpp.Node.Node node, required OptionalTypeParameterDeclaration &cast)`	Finds `OptionalTypeParameterDeclaration` nodes from `node` when compatible.
`name(OptionalTypeParameterDeclaration self, Cpp.Node.Node &child)`	Matches the template parameter name.
`defaultType(OptionalTypeParameterDeclaration self, Cpp.Node.Node &child)`	Matches the default type of the template parameter.
`isEnclosedInOptionalTypeParameterDeclaration(Cpp.Node.Node child)`	Checks if `child` appears inside an `OptionalTypeParameterDeclaration`.
`getEnclosingOptionalTypeParameterDeclaration(Cpp.Node.Node child, required OptionalTypeParameterDeclaration &parent)`	Finds the nearest enclosing `OptionalTypeParameterDeclaration` ancestor of `child`.
