| static const HeaderMap * | Create (const FileEntry *FE, FileManager &FM) |
This class represents an Apple concept known as a 'header map'. To the #include file resolution process, it basically acts like a directory of symlinks to files. Its advantages are that it is dense and more efficient to create and process than a directory of symlinks.

HeaderMap::Create - This attempts to load the specified file as a header map. If it doesn't look like a HeaderMap, it gives up and returns null.
HeaderMap::Create - This attempts to load the specified file as a header map. If it doesn't look like a HeaderMap, it gives up and returns null. If it looks like a HeaderMap but is obviously corrupted, it puts a reason into the string error argument and returns null.

LookupFile - Check to see if the specified relative filename is located in this HeaderMap. If so, open it and return its FileEntry. If RawPath is not NULL and the file is found, RawPath will be set to the raw path at which the file was found in the file system. For example, for a search path ".." and a filename "../file.h" this would be "../../file.h".
