Constructor Details

SimpleCpa

public SimpleCpa(TransferRelation<StateT> transferRelation,
 MergeOperator<StateT> mergeOperator,
 StopOperator<StateT> stopOperator)

Create a simple CPA with a static precision adjustment.

Parameters:

abstractDomain - a join-semilattice of AbstractStates defining the abstraction level of the analysis

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

SimpleCpa

public SimpleCpa(TransferRelation<StateT> transferRelation,
 MergeOperator<StateT> mergeOperator,
 StopOperator<StateT> stopOperator,
 PrecisionAdjustment precisionAdjustment,
 AbortOperator abortOperator)

Create a simple CPA from ConfigurableProgramAnalysis components.

Parameters:

abstractDomain - a join-semilattice of AbstractStates defining the abstraction level of the analysis

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

abortOperator - an operator used to terminate the analysis prematurely.
