Class PropExpressionNormaliser

java.lang.Object

uk.ac.ed.epcc.safe.accounting.expr.PropExpressionNormaliser

All Implemented Interfaces:

PropExpressionVisitor<PropExpression>, BasePropExpressionVisitor<PropExpression>

public class PropExpressionNormaliser
extends java.lang.Object
implements PropExpressionVisitor<PropExpression>

A PropExpressionVisitor that re-writes a PropExpression to normalised form. Mostly it copies through the input expression. This is intended to perform simple optimisations. Note it will not expand PropertyTags as these may have different expansions on different objects and PropExpressions may dereference to other objects.
