Detailed Description

The TraceCallExtractor class parses an OpenGL trace output generated by a GraphicsManager, segmenting it into a vector of calls with arguments.

It also contains utility functions to locate and count particular calls. Calls are tested using one or more strings that must match the beginnings of the resulting trace strings. This scheme is used, rather than exact full-string matches, to allow for differences in trace formatting on different platforms.

size_t ion::gfx::TraceCallExtractor::GetNthIndexOf	(	size_t	n,
		const std::string &	call_prefix
	)		const

Returns the index of the nth call in the trace stream beginning with start, if it exists, otherwise returns base::kInvalidIndex.

Note that n == 0 returns the first index, n == 1 returns the second index, and so on.
