public interface AbstractState<StateT extends AbstractState<StateT>>
An AbstractState contains information about the program state.

Abstract states are meant as part of a join-semilattice representing the domain of the analysis and implement operations over this set. In particular the states should be able to determine whether they are below another state in the partial order and to calculate the least upper bound on the semilattice when another state is provided (i.e., join operation).

    Modifier and Type
    Method
    Description
    StateT
    copy()
    Creates a copy of itself.
    boolean
    equals(Object obj)
     
    default Precision
    getPrecision()
    Returns the Precision used by the PrecisionAdjustment.
    int
    hashCode()
     
    default boolean
    isLess(StateT abstractStateT)
    Strictly compares itself to the abstractState.
    boolean
    isLessOrEqual(StateT abstractState)
    Compares itself to the abstractState (i.e., compare the states on the partial order provided by the domain of the analysis).
    StateT
    join(StateT abstractState)
    Computes a join over itself and another abstract state abstractState (i.e., finds the least upper bound on the semilattice).

    • join

      StateT join(StateT abstractState)
