Member Function Documentation

get()

BFNContext & BFNContext::get ( )

static

Returns

the current compilation context, which must be of type BFNContext.

getOutputDirectory()

cstring BFNContext::getOutputDirectory	(	const cstring &	suffix = cstring(),
		int	pipe_id = -1 )

Returns

a string that represents a path to an output directory: options.outputDir + pipename + suffix If pipe_id is not set (-1) return just options.outputDir. No other files except for the manifest should be stored in the root. If suffix is empty, return options.outputDir + pipename.

The structure of the output directory is: options.outputDir / manifest.json for each pipe / pipeName/context.json / pipeName/tofino[x].bin / pipeName/program.bfa / pipeName/program.res.json / pipeName/logs/ / pipeName/graphs/

If the directory does not exists, it is created. If the creation fails print an error message and return an empty string. FIXME: Make this return std::filesystem::path. There are quite a few invocations of this function.

options()

BFN_Options & BFNContext::options ( )

override

Returns

the compiler options for this compilation context.
