Class ReflectionComparatorFactory

java.lang.Object

org.unitils.reflectionassert.ReflectionComparatorFactory

public class ReflectionComparatorFactory
extends Object

A factory for creating a reflection comparator. This will assemble the apropriate comparator chain and constructs a reflection comparator.

By default, a strict comparison is performed, but if needed, some leniency can be configured by setting one or more comparator modes:

• ignore defaults: all fields that have a default java value for the left object will be ignored. Eg if the left object contains an int field with value 0 it will not be compared to the value of the right object.
• lenient dates: only check whether both Date objects contain a value or not, the value itself is not compared. Eg. if the left object contained a date with value 1-1-2006 and the right object contained a date with value 2-2-2006 they would still be considered equal.
• lenient order: only check whether both collections or arrays contain the same value, the actual order of the values is not compared. Eg. if the left object is int[]{ 1, 2} and the right value is int[]{2, 1} they would still be considered equal.

Method Detail

createRefectionComparator

public static ReflectionComparator createRefectionComparator(ReflectionComparatorMode... modes)

Creates a reflection comparator for the given modes. If no mode is given, a strict comparator will be created.

Parameters:

modes - The modes, null for strict comparison

Returns:

The reflection comparator, not null

getComparatorChain

protected static List<Comparator> getComparatorChain(Set<ReflectionComparatorMode> modes)

Creates a comparator chain for the given modes. If no mode is given, a strict comparator will be created.

Parameters:

modes - The modes, null for strict comparison

Returns:

The comparator chain, not null
