Class ValueParserPolicy

java.lang.Object

uk.ac.ed.epcc.safe.accounting.parsers.value.ValueParserPolicy

All Implemented Interfaces:

PropExpressionVisitor<ValueParser>, BasePropExpressionVisitor<ValueParser>

public class ValueParserPolicy
extends java.lang.Object
implements PropExpressionVisitor<ValueParser>

A PropExpressionVisitor to create a ValueParser appropriate to a PropExpression. This class defaults to using the ValueParserService but can be sub-classed to customise the behaviour. This class also caches the ValueParsers by PropertyTag so a single visitor should be used for an entire parse pass.
