Constructor Detail

CpaAlgorithm

public CpaAlgorithm(ConfigurableProgramAnalysis cpa)

Create an algorithm to run the specified CPA.

Parameters:

cpa - a CPA instance wrapping the transfer relation, the merge, and the stop operator, and the precision adjustment

CpaAlgorithm

public CpaAlgorithm(TransferRelation transferRelation,
                    MergeOperator mergeOperator,
                    StopOperator stopOperator,
                    PrecisionAdjustment precisionAdjustment)

Create a CPA algorithm from CPA components.

Parameters:

transferRelation - a transfer relation specifying how successor states are computed

mergeOperator - a merge operator defining how (and whether) the older AbstractState should be updated with the newly discovered AbstractState

stopOperator - a stop operator deciding whether the successor state should be added to the ReachedSet based on the content of the latter

precisionAdjustment - a precision adjustment selecting the Precision for the currently processed AbstractState considering the ReachedSet content

Method Detail

run

public void run(ReachedSet reachedSet,
                Waitlist waitlist,
                AbortOperator abortOperator)

Algorithm from the paper is parametrized with the reached set and the waitlist. Thus one can select the start point of the algorithm (e.g., for resuming the analysis). The abortOperator determines whether the analysis should end prematurely.
