Field Detail

sortCriterias

protected ArrayList sortCriterias

Sort criteria list. Each entry contains a criteria properties array of int[2] (criteria id. and ordering mode). The position in the list determines the criteria priority in descending order: the first criteria into the list is the most prioritary.

locale

protected Locale locale

The criteria locale.

public AbstractComparatorByCriteria()

Method Detail

getLocale

public Locale getLocale()

Description copied from interface: ComparatorByCriteria

The criteria always belongs to a locale.

Specified by:

getLocale in interface ComparatorByCriteria

setLocale

public void setLocale(Locale locale)

Specified by:

setLocale in interface ComparatorByCriteria

addSortCriteria

public void addSortCriteria(String criteriaId,
                            int order)

Description copied from interface: ComparatorByCriteria

Specifies a sort criteria for the comparator.

Specified by:

addSortCriteria in interface ComparatorByCriteria

Parameters:

criteriaId - The criteria to set.

order - The sort order. See ORDER_ constants defined.

removeSortCriteria

public void removeSortCriteria(String criteriaId)

Description copied from interface: ComparatorByCriteria

Removes a sort criteria.

Specified by:

removeSortCriteria in interface ComparatorByCriteria

Parameters:

criteriaId - The criteria to remove.

removeAllSortCriteria

public void removeAllSortCriteria()

Description copied from interface: ComparatorByCriteria

Removes all sort criterias.

Specified by:

removeAllSortCriteria in interface ComparatorByCriteria

getSortCriteriaPriority

public int getSortCriteriaPriority(String criteriaId)

Description copied from interface: ComparatorByCriteria

Retrieves the current priority for a given criteria. Priority is set when the criteria is specified. The first criteria specified is the most prioritary.

Specified by:

getSortCriteriaPriority in interface ComparatorByCriteria

Parameters:

criteriaId - The criteria to set.

Returns:

The priority from 1 to <max. number of criterias>.
0 if criteria is not specified in this comparator.

Specified by:

getSortCriteriaOrdering in interface ComparatorByCriteria

Parameters:

criteriaId - The criteria to set. See CRITERIA_ constants defined.

getCriteriaIds

public String[] getCriteriaIds()

Description copied from interface: ComparatorByCriteria

existCriteria

public boolean existCriteria(String criteriaId)

Description copied from interface: ComparatorByCriteria

Check if a given criteria is applied in comparator.

Specified by:

existCriteria in interface ComparatorByCriteria

equals

public boolean equals(Object obj)

Specified by:

equals in interface Comparator

Overrides:

equals in class Object

compare

public abstract int compare(Object o1,
