Constructor Detail

DynaComparator

public DynaComparator(boolean sortAscending)

default constructor - assumes comparator for Type List

For Example-

List<Integer> aa = new ArrayList<Integer>();
List<String> bb = new ArrayList<String>();
List<Date> cc = new ArrayList<Date>();

and so on..

Invoking sort method with passing DynaComparator for
Collections.sort(aa, new DynaComparator(false));

Parameters:

sortAscending - - a boolean - true ascending order or false descending order

DynaComparator

public DynaComparator(String getterMethod)

constructor with sortField parameter for Derived type of Class default sorting is ascending order

For Example-

PersonVO person = new PersonVO();
person.setId(10001);
person.setName("Jacob");
person.setHeight(5.2F);
person.setEmailId("[email protected]");
person.setSalary(10500L);
person.setDob(new SimpleDateFormat("MMMM d, yyyy", Locale.ENGLISH).parse("Jan 1, 1970"));


and person2, person3, so on.. And Defining & adding all the created objects in to below list

List<PersonVO> persons = new ArrayList<PersonVO>();
persons.add(person1);
persons.add(person2);
persons.add(person3); and so on

Invoking sort method with passing DynaComparator for
Collections.sort(persons, new DynaComparator("getName"));

Parameters:

getterMethod - - a String - which field requires sorting; as per above example "sorting required for getNname getter"

DynaComparator

public DynaComparator(String getterMethod,
              boolean sortAscending)

constructor with sortField, sortAscending parameter for Derived type of Class

For Example-

PersonVO person = new PersonVO();

person.setName("Jacob");
person.setHeight(5.2F);
person.setEmailId("[email protected]");
person.setSalary(10500L);
person.setDob(new SimpleDateFormat("MMMM d, yyyy", Locale.ENGLISH).parse("Jan 1, 1970"));


and person2, person3, so on.. And Defining & adding all the created objects in to below list

List<PersonVO> persons = new ArrayList<PersonVO>();
persons.add(person1);
persons.add(person2);
persons.add(person3); and so on

Invoking sort method with passing DynaComparator for
Collections.sort(persons, new DynaComparator("getName", false));

Parameters:

getterMethod - - a String - which field requires sorting; as per above example "sorting required for name getter"
