Detailed Description

Class for calculating "goodness of fit" of parameter trials against a prototype model.

The class is instantiated with a prototype model (ProtoModel). A set of Varnode parameter trials are registered by calling addParameter() for each trial. Then calling doScore() computes a score that evaluates how well the set of registered trials fit the prototype model. A lower score indicates a better fit.

Constructor & Destructor Documentation

ScoreProtoModel::ScoreProtoModel	(	bool	isinput,
		const ProtoModel *	mod,
		int4	numparam
	)

Constructor.

Parameters

isinput	is set to true to compute scores against the input part of the model
mod	is the prototype model to score against
numparam	is the presumed number of trials that will constitute the score

Member Function Documentation

void ScoreProtoModel::addParameter	(	const Address &	addr,
		int4	sz
	)

Register a trial to be scored.

Parameters

addr	is the starting address of the trial
sz	is the number of bytes in the trial
