|
inlineoverridevirtual |
Callback invoked whenever an inclusion directive of any kind (#include
, #import
, etc.) has been processed, regardless of whether the inclusion will actually result in an inclusion.
HashLoc | The location of the '#' that starts the inclusion directive. |
IncludeTok | The token that indicates the kind of inclusion directive, e.g., 'include' or 'import'. |
FileName | The name of the file being included, as written in the source code. |
IsAngled | Whether the file name was enclosed in angle brackets; otherwise, it was enclosed in quotes. |
FilenameRange | The character range of the quotes or angle brackets for the written file name. |
File | The actual file that may be included by this inclusion directive. |
SearchPath | Contains the search path which was used to find the file in the file system. If the file was found via an absolute include path, SearchPath will be empty. For framework includes, the SearchPath and RelativePath will be split up. For example, if an include of "Some/Some.h" is found via the framework path "path/to/Frameworks/Some.framework/Headers/Some.h", SearchPath will be "path/to/Frameworks/Some.framework/Headers" and RelativePath will be "Some.h". |
RelativePath | The path relative to SearchPath, at which the include file was found. This is equal to FileName except for framework includes. |
Imported | The module, whenever an inclusion directive was automatically turned into a module import or null otherwise. |
FileType | The characteristic kind, indicates whether a file or directory holds normal user code, system code, or system code which is implicitly 'extern "C"' in C++ mode. |
