- // fast_source_line_resolver.h: FastSourceLineResolver is derived from
- // SourceLineResolverBase, and is a concrete implementation of
- // SourceLineResolverInterface.
- //
- // FastSourceLineResolver is a sibling class of BasicSourceLineResolver. The
- // difference is FastSourceLineResolver loads a serialized memory chunk of data
- // which can be used directly a Module without parsing or copying of underlying
- // data. Therefore loading a symbol in FastSourceLineResolver is much faster
- // and more memory-efficient than BasicSourceLineResolver.
- //
- // See "source_line_resolver_base.h" and
- // "google_breakpad/source_line_resolver_interface.h" for more reference.
