Package de.hybris.platform.acceleratorstorefrontcommons.variants.impl

Class DefaultVariantSortStrategy

java.lang.Object

de.hybris.platform.acceleratorstorefrontcommons.variants.impl.DefaultVariantSortStrategy

All Implemented Interfaces:

VariantSortStrategy, Comparator<VariantOptionData>

public class DefaultVariantSortStrategy
extends Object
implements VariantSortStrategy

Default strategy for comparing variants.
Use sortingFieldsOrder property to set up attributes to sort by. E.g give A,B attributes and sorting will be performed first against A attribute and if two values are considered equal (by A) then values of B attribute are compared.
Use comparators to provide comparators for particular attributes

Method Details

getSortingFieldsOrder

protected List<String> getSortingFieldsOrder()

setSortingFieldsOrder

public void setSortingFieldsOrder(List<String> sortingFieldsOrder)

Description copied from interface: VariantSortStrategy

Sets the sorting fields order. String array contains variant attributes that will be used to compare variants. When the method was not called or empty list was passed no sorting will be performed.

Specified by:

setSortingFieldsOrder in interface VariantSortStrategy

Parameters:

sortingFieldsOrder - the new sorting fields order

getComparators

protected Map<String,Comparator<String>> getComparators()

setComparators

public void setComparators(Map<String,Comparator<String>> comparators)

Description copied from interface: VariantSortStrategy

Map of attribute - comparator. Where attribute is variant attribute to compare for sorting

Specified by:

setComparators in interface VariantSortStrategy

getDefaultComparator

protected Comparator<String> getDefaultComparator()

setDefaultComparator

public void setDefaultComparator(Comparator<String> defaultComparator)

Specified by:

setDefaultComparator in interface VariantSortStrategy

Parameters:

defaultComparator - for comparing variants' values - used as fallback, provide your own in VariantSortStrategy.setComparators(Map)

compare

public int compare(VariantOptionData product1,
 VariantOptionData product2)

Specified by:

compare in interface Comparator<VariantOptionData>

getVariantValue

protected String getVariantValue(String field,
 VariantOptionData variant)

getComparator

protected Comparator<String> getComparator(String field)
