StackAbstractState<AbstractSpaceT>	copy()	Creates a copy of itself.
boolean	isLessOrEqual(StackAbstractState<AbstractSpaceT> abstractState)	Compares itself to the abstractState (i.e., compare the states on the partial order provided by the domain of the analysis).

Method Detail

join

public StackAbstractState<AbstractSpaceT> join(StackAbstractState<AbstractSpaceT> abstractState)

Description copied from interface: AbstractState

Computes a join over itself and another abstract state abstractState (i.e., finds the least upper bound on the semilattice).

Specified by:

join in interface AbstractState<AbstractSpaceT extends AbstractState<AbstractSpaceT>>

isLessOrEqual

public boolean isLessOrEqual(StackAbstractState<AbstractSpaceT> abstractState)

Description copied from interface: AbstractState

Compares itself to the abstractState (i.e., compare the states on the partial order provided by the domain of the analysis).

Specified by:

isLessOrEqual in interface AbstractState<AbstractSpaceT extends AbstractState<AbstractSpaceT>>

copy

public StackAbstractState<AbstractSpaceT> copy()

Description copied from interface: AbstractState

Creates a copy of itself.

Specified by:

copy in interface AbstractState<AbstractSpaceT extends AbstractState<AbstractSpaceT>>

popOrDefault

public AbstractSpaceT popOrDefault(AbstractSpaceT defaultState)

Removes the top of the stack and returns it. If the stack is empty, it returns the defaultState.

peek

public AbstractSpaceT peek(int index)

Returns the indexth element from the top of the stack. If the stack does not have enough elements, it throws an exception.

peekOrDefault

public AbstractSpaceT peekOrDefault(int index,
                                    AbstractSpaceT defaultState)

Returns the indexth element from the top of the stack. If the stack does not have enough elements, it returns the defaultState.
