Class ValueRestriction

java.lang.Object
  org.omwg.mediation.mappingstore.query.ValueRestriction

All Implemented Interfaces:

Restriction

public class ValueRestriction

extends java.lang.Object

implements Restriction

The ValueRestriction is used to implement range restriction or equals for numbers. To add a range restriction use two ValueRestrictions with LOWER and UPPER bounds.

Field Summary

static int	EQUAL
static int	LOWER
static int	NO_RESTRICTION
static int	UPPER

Constructor Summary

ValueRestriction(int typeOfRestriction, java.lang.Comparable value)
Constructs basic restriction by comparable object and type.

Method Summary

boolean	admit(java.lang.Object o) This method is speciifed by Restriction Interface

Constructor Detail

ValueRestriction

public ValueRestriction(int typeOfRestriction,
                        java.lang.Comparable value)

Constructs basic restriction by comparable object and type. The range of the first argument is set of values of class variables referring to the type of the restriction.

Parameters:

typeOfRestriction - given restriction type

value - given comparable object

Method Detail

admit

public boolean admit(java.lang.Object o)

This method is speciifed by Restriction Interface

Specified by:

admit in interface Restriction

Parameters:

o - given object of type Comparable

Returns:

True if the Comparable object satisfies the restrictions, otherwise returns False.

reduceToLuceneQuery

public java.lang.String reduceToLuceneQuery(java.lang.String field)

Specified by:

reduceToLuceneQuery in interface Restriction
