Package it.unive.lisa.analysis.nonrelational

Interface NonRelationalDomain<T extends NonRelationalDomain<T,E,F>,E extends SymbolicExpression,F extends Environment<F,E,T>>

Type Parameters:

T - the concrete type of the domain

E - the type of expressions that this domain can evaluate

F - the type of functional lattice that is used in conjunction with this domain

All Superinterfaces:

Lattice<T>, NonRelationalElement<T,E,F>, SemanticEvaluator, StructuredObject

All Known Subinterfaces:

BaseNonRelationalTypeDomain<T>, BaseNonRelationalValueDomain<T>, NonRelationalHeapDomain<T>, NonRelationalTypeDomain<T>, NonRelationalValueDomain<T>

public interface NonRelationalDomain<T extends NonRelationalDomain<T,E,F>,E extends SymbolicExpression,F extends Environment<F,E,T>>
extends NonRelationalElement<T,E,F>

A NonRelationalElement that models the standard concept of non-relational abstract domain, and that is able to compute the value of a SymbolicExpressions of type E by knowing the values of all program variables. Instances of this class can be wrapped inside an FunctionalLattice to represent abstract values of individual Identifiers.

Method Detail

eval

T eval(E expression,
       F environment,
       ProgramPoint pp,
       SemanticOracle oracle)
throws SemanticException

Evaluates a SymbolicExpression, assuming that the values of program variables are the ones stored in environment.

Parameters:

expression - the expression to evaluate

environment - the environment containing the values of program variables for the evaluation

pp - the program point that where this operation is being evaluated

oracle - the oracle for inter-domain communication

Returns:

an new instance of this domain, representing the abstract result of expression when evaluated on environment

Throws:

SemanticException - if something goes wrong during the computation
