Enumeration Type Documentation

◆ CXNameRefFlags

Enumerator
CXNameRange_WantQualifier 

Include the nested-name-specifier, e.g.

Foo:: in x.Foo::y, in the range.

CXNameRange_WantTemplateArgs 

Include the explicit template arguments, e.g.

<int> in x.f<int>, in the range.

CXNameRange_WantSinglePiece 

If the name is non-contiguous, return the full spanning range.

Non-contiguous names occur in Objective-C when a selector with two or more parameters is used, or in C++ when using an operator:

[object doSomething:here withValue:there]; // Objective-C
return some_vector[1]; // C++

◆ clang_getCursorReferenceNameRange()

CINDEX_LINKAGE CXSourceRange clang_getCursorReferenceNameRange ( CXCursor  C,
unsigned  NameFlags,
unsigned  PieceIndex 
)

Given a cursor that references something else, return the source range covering that reference.

Parameters
CA cursor pointing to a member reference, a declaration reference, or an operator call.
NameFlagsA bitset with three independent flags: CXNameRange_WantQualifier, CXNameRange_WantTemplateArgs, and CXNameRange_WantSinglePiece.
PieceIndexFor contiguous names or when passing the flag CXNameRange_WantSinglePiece, only one piece with index 0 is available. When the CXNameRange_WantSinglePiece flag is not passed for a non-contiguous names, this index can be used to retrieve the individual pieces of the name. See also CXNameRange_WantSinglePiece.
Returns
The piece of the name pointed to by the given cursor. If there is no name, or if the PieceIndex is out-of-range, a null-cursor will be returned.

◆ clang_getSpecializedCursorTemplate()

CINDEX_LINKAGE CXCursor clang_getSpecializedCursorTemplate ( CXCursor  C)

Given a cursor that may represent a specialization or instantiation of a template, retrieve the cursor that represents the template that it specializes or from which it was instantiated.

This routine determines the template involved both for explicit specializations of templates and for implicit instantiations of the template, both of which are referred to as "specializations". For a class template specialization (e.g., std::vector<bool>), this routine will return either the primary template (std::vector) or, if the specialization was instantiated from a class template partial specialization, the class template partial specialization. For a class template partial specialization and a function template specialization (including instantiations), this this routine will return the specialized template.

For members of a class template (e.g., member functions, member classes, or static data members), returns the specialized or instantiated member. Although not strictly "templates" in the C++ language, members of class templates have the same notions of specializations and instantiations that templates do, so this routine treats them similarly.

Parameters
CA cursor that may be a specialization of a template or a member of a template.
Returns
If the given cursor is a specialization or instantiation of a template or a member thereof, the template or member that it specializes or from which it was instantiated. Otherwise, returns a NULL cursor.

◆ clang_getTemplateCursorKind()

CINDEX_LINKAGE enum CXCursorKind clang_getTemplateCursorKind ( CXCursor  C)

Given a cursor that represents a template, determine the cursor kind of the specializations would be generated by instantiating the template.

This routine can be used to determine what flavor of function template, class template, or class template partial specialization is stored in the cursor. For example, it can describe whether a class template cursor is declared with "struct", "class" or "union".

Parameters
CThe cursor to query. This cursor should represent a template declaration.
Returns
The cursor kind of the specializations that would be generated by instantiating the template C. If C is not a template, returns CXCursor_NoDeclFound.
