Detailed Description

Data structure that captures multiple levels of template argument lists for use in template instantiation.

Multiple levels of template arguments occur when instantiating the definitions of member templates. For example:

template<typename T>
struct X {
template<T Value>
struct Y {
void f();
};
};

When instantiating X<int>::Y<17>::f, the multi-level template argument list will contain a template argument list (int) at depth 0 and a template argument list (17) at depth 1.

Member Function Documentation

◆ addOuterRetainedLevel()

void clang::MultiLevelTemplateArgumentList::addOuterRetainedLevel ( )
inline

Add an outermost level that we are not substituting.

We have no arguments at this level, and do not remove it from the depth of inner template parameters that we instantiate.

Definition at line 149 of file Template.h.

◆ addOuterTemplateArguments() [1/2]

void clang::MultiLevelTemplateArgumentList::addOuterTemplateArguments ( const TemplateArgumentList TemplateArgs)
inline

◆ addOuterTemplateArguments() [2/2]

void clang::MultiLevelTemplateArgumentList::addOuterTemplateArguments ( ArgList  Args)
inline

Add a new outmost level to the multi-level template argument list.

Definition at line 140 of file Template.h.

◆ getInnermost()

const ArgList& clang::MultiLevelTemplateArgumentList::getInnermost ( ) const
inline

◆ getNumLevels()

unsigned clang::MultiLevelTemplateArgumentList::getNumLevels ( ) const
inline

Determine the number of levels in this template argument list.

Definition at line 88 of file Template.h.

◆ getNumSubstitutedLevels()

unsigned clang::MultiLevelTemplateArgumentList::getNumSubstitutedLevels ( ) const
inline

Determine the number of substituted levels in this template argument list.

Definition at line 94 of file Template.h.

◆ hasTemplateArgument()

bool clang::MultiLevelTemplateArgumentList::hasTemplateArgument ( unsigned  Depth,
unsigned  Index 
) const
inline

Determine whether there is a non-NULL template argument at the given depth and index.

There must exist a template argument list at the given depth.

Definition at line 109 of file Template.h.

◆ operator()()

const TemplateArgument& clang::MultiLevelTemplateArgumentList::operator() ( unsigned  Depth,
unsigned  Index 
) const
inline

Retrieve the template argument at a given depth and index.

Definition at line 99 of file Template.h.

◆ setArgument()

void clang::MultiLevelTemplateArgumentList::setArgument ( unsigned  Depth,
unsigned  Index,
TemplateArgument  Arg 
)
inline

Clear out a specific template argument.
