Package it.unive.lisa.analysis.value

Interface ValueDomain<D extends ValueDomain<D>>

Type Parameters:

D - the concrete type of the ValueDomain

All Superinterfaces:

Lattice<D>, ScopedObject<D>, SemanticDomain<D,ValueExpression,Identifier>, StructuredObject, ValueOracle

All Known Subinterfaces:

TypeDomain<T>

All Known Implementing Classes:

DataflowDomain, DefiniteDataflowDomain, InferenceSystem, PossibleDataflowDomain, TypeEnvironment, ValueEnvironment

public interface ValueDomain<D extends ValueDomain<D>>
extends ValueOracle, SemanticDomain<D,ValueExpression,Identifier>, Lattice<D>

A semantic domain that can evaluate the semantic of statements that operate on values, and not on memory locations. A value domain can handle instances of ValueExpressions, and manage identifiers that are Variables.

Method Detail

applyReplacement

default D applyReplacement(HeapSemanticOperation.HeapReplacement r,
                           ProgramPoint pp,
                           SemanticOracle oracle)
                    throws SemanticException

Applies a substitution of identifiers that is caused by a modification of the abstraction provided in the HeapDomain of the analysis. A substitution is composed by a list of HeapSemanticOperation.HeapReplacement instances, that must be applied in order.

Parameters:

r - the replacement to apply

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

oracle - the oracle for inter-domain communication

Returns:

the value domain instance modified by the substitution

Throws:

SemanticException - if an error occurs during the computation
