This class provides a public static resolve method that, given a vector of StackTraceFrames that have only their address fields set, resolves as many other fields in those frames as possible. The Elf object file format is used on Linux and Solaris platforms. On Linux, some Elf sections contain data in the DWARF format, which makes it possible to resolve line numbers and file names.

class ResolverImpl<ObjectFileFormat::Elf>;| Name | Description |
|---|---|
numUnmatchedFrames | Return the number of frames in the stack trace that are still unmatched. |
processLoadedImage | Process a loaded image found via the link map, either the main program or some shared library. The specified libraryFileName is the name of the file containing the image. The specified programHeaders is a pointer to an array of elf program headers and the specified numProgramHeaders is its length, it is a void * because the type ElfProgramHeader is local to the implementation file. Specify one of textSegPtr and baseAddress, and the other as 0, this method will infer the one specified as 0 from the other. Specify isMainExecutable, indicating whether the image is the main executable. Return 0 on success and a non-zero value otherwise. Note that this method is not to be called by external users of this component, it is only public so a static routine in the implementation file can call it. Also note that if isMainExecutable is set, libraryFileName is ignored and the argv[0] the program was called with is used in its place. |
| Name | Description |
|---|---|
resolve | Populate information for the specified *stackTrace, which contains a sequence of randomly-accessible stack trace frames. Specify demanglingPreferredFlag, to determine whether demangling is to occur. The behavior is undefined unless all the address field in *stackTrace are valid and other fields are invalid. |
test | This function is just there to test how code deals with inline functions in an include file. It does not provide any otherwise useful functionality. Return a line number near the beginning of the function in the low-order 14 bits of the result. Other bits of the result are to be considered garbage. |
