const

Get the depth of this template parameter list in the set of template parameter lists.

The first template parameter list in a declaration will have depth 0, the second template parameter list will have depth 1, etc.

getMinRequiredArguments()

unsigned TemplateParameterList::getMinRequiredArguments

const

Returns the minimum number of arguments needed to form a template specialization.

This may be fewer than the number of template parameters, if some of the parameters have default arguments or if there is a parameter pack.
