Method Detail

reset

public void reset(ConcreteState initialConcreteState,
         SymbolicState initialSymbolicState)

Resets the trace with the given parameters. Set both parameters to initialize a combined symbolic and concrete trace. If both parameters are null the trace will be useless, and the append methods will throw IllegalStateExceptions.

Parameters:

initialConcreteState - the initial concrete state. If null this trace will not be concrete.

initialSymbolicState - the initial symbolic state. If null this trace will not be symbolic.

clearAfterState

public void clearAfterState(int i)

append

public void append(BigDecimal delay,
          SystemEdge[] transitionEdges,
          ConcreteState concreteState,
          SymbolicState symbolicState)

append

public void append(BigDecimal delay,
          SystemEdge[] transitionEdges,
          ConcreteState concreteState)

append

public void append(SystemEdge[] transitionEdges,
          SymbolicState symbolicState)

getEntryTime

public BigDecimal getEntryTime(int i)

getDelay

public BigDecimal getDelay(int i)

Returns:

The i'th delay. Null if the i'th delay is undefined.

getTransitionEdges

public SystemEdge[] getTransitionEdges(int i)

getSymbolicTransition

public SymbolicTransition getSymbolicTransition(int i)

Warning: In this representation of the trace, all transitions have a source and a destination, meaning that compared with the old symbolic trace representation, the initial transition is missing. The initial transition was a (null,null,initialState) transition and was a hack necessary only in the old symbolic trace representation. Therefore it will not be reflected by this new trace representation. This warning can be removed when all of the old symbolic trace is gone.

Returns:

The i'th symbolic transition. Null if the i'th symbolic transition is undefined.

getConcreteState

public ConcreteState getConcreteState(int i)

getSymbolicState

public SymbolicState getSymbolicState(int i)
