Detailed Description

This class is a separate subset of options for running an experiment. These options can be specified by a spec string that looks like: "id=<number greater than 0>;level=<rewrite level>="">;enabled= <comma-separated-list of filters to enable>;disabled= <comma-separated-list of filters to disable>;options= <comma-separated-list of option=value pairs to set>.

Constructor & Destructor Documentation

net_instaweb::RewriteOptions::ExperimentSpec::ExperimentSpec	(	const StringPiece &	spec,
		const RewriteOptions *	options,
		MessageHandler *	handler
	)

Creates a ExperimentSpec parsed from spec. If spec doesn't have an id, then id_ will be set to experiment::kExperimentNotSet. These ExperimentSpecs will then be rejected by AddExperimentSpec().

net_instaweb::RewriteOptions::ExperimentSpec::ExperimentSpec ( int id )

explicit

Creates a ExperimentSpec with id_=id. All other variables are initialized to 0. This is primarily used for setting up the control and for cloning.

Member Function Documentation

static void net_instaweb::RewriteOptions::ExperimentSpec::CombineQuotedHostPort	(	StringPieceVector *	vec,
		size_t	first_pos,
		GoogleString *	combined_container
	)

staticprotected

Combine consecutive entries in a StringPieceVector such that [ a, b, "host, port" ] can be turned into [ a, b, host:port ]. Inspects vec[first_pos] and vec[first_pos + 1]. If they appear to be a quoted tuple, will replace vec[first_pos] with a combined value and vec[first_pos + 1] will be removed, ie: vec will reduce in size by 1. combined_container is used as the underlying storage for the combined string, if necessary.

static bool net_instaweb::RewriteOptions::ExperimentSpec::LooksLikeValidHost ( const StringPiece & s )

staticprotected

Simple check that 's' is not obviously an invalid host. Used to avoid problems when a port number is accidentally placed in a host field.

void net_instaweb::RewriteOptions::ExperimentSpec::Merge ( const ExperimentSpec & spec )

protected

Merges a spec into this. This follows the same semantics as RewriteOptions. Specifically, filter/options list get unioned, and vars get overwritten, except ID. In the event of a conflict, e.g. preserve vs extend_cache, *this will take precedence.

static bool net_instaweb::RewriteOptions::ExperimentSpec::ParseAlternateOriginDomain	(	const StringPiece &	in,
		AlternateOriginDomainSpec *	out,
		MessageHandler *	handler
	)

staticprotected

Parses the string after an 'alternate_origin_domain' experiment option, returning if it was successfull. If it returns false, the spec is invalid and should be discarded.

static GoogleString net_instaweb::RewriteOptions::ExperimentSpec::QuoteHostPort ( const GoogleString & in )

staticprotected

Returns a copy of the input string that will be surrounded by double quotes if the input string contains a colon. This is used to turn host:port into "host:port" when printing an ExperimentSpec.
