java.lang.Object

it.unive.lisa.analysis.heap.BaseHeapDomain.Rewriter

All Implemented Interfaces:

ExpressionVisitor<ExpressionSet<ValueExpression>>

Direct Known Subclasses:

PointBasedHeap.Rewriter

Enclosing class:

BaseHeapDomain<H extends BaseHeapDomain<H>>

protected abstract static class BaseHeapDomain.Rewriter
extends java.lang.Object
implements ExpressionVisitor<ExpressionSet<ValueExpression>>

An ExpressionVisitor that rewrites SymbolicExpressions to ValueExpressions. The visiting of HeapExpressions is left unimplemented for concrete instances to provide their logic.

visit

public final ExpressionSet<ValueExpression> visit(UnaryExpression expression,
                                                  ExpressionSet<ValueExpression> arg,
                                                  java.lang.Object... params)
                                           throws SemanticException

Description copied from interface: ExpressionVisitor

Visits a UnaryExpression. This callback is invoked after the inner expressions have been visited, and their produced value is passed as argument.

Specified by:

visit in interface ExpressionVisitor<ExpressionSet<ValueExpression>>

Parameters:

expression - the expression

arg - the value produced by visiting the argument of the expression

params - the additional parameters provided to SymbolicExpression.accept(ExpressionVisitor, Object...), if any

Returns:

the value produced by visiting the expression

Throws:

SemanticException - if an error occurs during the visit operation

visit

public final ExpressionSet<ValueExpression> visit(BinaryExpression expression,
                                                  ExpressionSet<ValueExpression> left,
                                                  ExpressionSet<ValueExpression> right,
                                                  java.lang.Object... params)
                                           throws SemanticException

Description copied from interface: ExpressionVisitor

Visits a BinaryExpression. This callback is invoked after the inner expressions have been visited, and their produced value is passed as argument.

Specified by:

visit in interface ExpressionVisitor<ExpressionSet<ValueExpression>>

Parameters:

expression - the expression

left - the value produced by visiting the left-hand side of the expression

right - the value produced by visiting the right-hand side of the expression

params - the additional parameters provided to SymbolicExpression.accept(ExpressionVisitor, Object...), if any

Returns:

the value produced by visiting the expression

Throws:

SemanticException - if an error occurs during the visit operation
