ListitemComparator
public class ListitemComparator implements Comparator(Code)
	A comparator used to compare Listitem , if not live data, or the data themselves, if live data. author: tomyeh

Constructor Summary
public	ListitemComparator() Compares with Listitem.getValue .
public	ListitemComparator(int index) Compares with the column of the specified index. 0 for the first column, 1 for the second and so on Note: -1 for Listitem.getValue and it assumes the value implements Comparable. Note: It assumes the ascending order, case-insensitive and comparing the returned values of Listcell.getLabel . If not, use ListitemComparator.ListitemComparator(int,boolean,boolean,boolean) instead. A null value is considered as the minimum value. Parameters: index - which column to compare.
public	ListitemComparator(int index, boolean ascending, boolean ignoreCase) Compares with the column of the specified index. 0 for the first column, 1 for the second and so on Note: -1 for Listitem.getValue and it assumes the value implements Comparable. Note: it compares the returned value of Listcell.getLabel . If you want to compare Listcell.getValue ., use ListitemComparator.ListitemComparator(int,boolean,boolean,boolean) instead. A null value is considered as the minimum value. Parameters: index - which column to compare.
public	ListitemComparator(int index, boolean ascending, boolean ignoreCase, boolean byValue) Compares with the column of the specified index. 0 for the first column, 1 for the second and so on Note: -1 for Listitem.getValue and it assumes the value implements Comparable. A null value is considered as the minimum value. Parameters: index - which column to compare.
public	ListitemComparator(int index, boolean ascending, boolean ignoreCase, boolean byValue, boolean nullAsMax) Compares with the column of the specified index. 0 for the first column, 1 for the second and so on Note: -1 for Listitem.getValue and it assumes the value implements Comparable. Parameters: index - which column to compare.
public	ListitemComparator(Listheader header, boolean ascending, boolean ignoreCase) Compares with the column which the list header is at.
public	ListitemComparator(Listheader header, boolean ascending, boolean ignoreCase, boolean byValue) Compares with the column which the list header is at.
public	ListitemComparator(Listheader header, boolean ascending, boolean ignoreCase, boolean byValue, boolean nullAsMax) Compares with the column which the list header is at.

Method Summary
public boolean	byValue()
public int	compare(Object o1, Object o2)
public boolean	equals(Object o)
public Listheader	getListheader() Returns the listheader that this comparator is associated with, or null if not available.
public int	hashCode()
public boolean	isAscending() Returns whether the order is ascending.
public boolean	shallIgnoreCase() Returns whether to ignore case.
public String	toString()

Constructor Detail

ListitemComparator

public ListitemComparator()(Code)

Compares with Listitem.getValue .

It assumes the value returned by Listitem.getValue implements Comparable.

Note: It assumes the ascending order and case-insensitive. If not, use ListitemComparator.ListitemComparator(int,boolean,boolean) instead.

ListitemComparator

public ListitemComparator(int index)(Code)

Compares with the column of the specified index.

0 for the first column, 1 for the second and so on

Note: -1 for Listitem.getValue and it assumes the value implements Comparable.

Note: It assumes the ascending order, case-insensitive and comparing the returned values of Listcell.getLabel . If not, use ListitemComparator.ListitemComparator(int,boolean,boolean,boolean) instead.

A null value is considered as the minimum value.
Parameters:
index - which column to compare. If -1, Listitem.getValueis used.

ListitemComparator

public ListitemComparator(int index, boolean ascending, boolean ignoreCase)(Code)

Compares with the column of the specified index.

0 for the first column, 1 for the second and so on

Note: -1 for Listitem.getValue and it assumes the value implements Comparable.

Note: it compares the returned value of Listcell.getLabel . If you want to compare Listcell.getValue ., use ListitemComparator.ListitemComparator(int,boolean,boolean,boolean) instead.

ListitemComparator

public ListitemComparator(int index, boolean ascending, boolean ignoreCase, boolean byValue)(Code)

Compares with the column of the specified index.

0 for the first column, 1 for the second and so on

Note: -1 for Listitem.getValue and it assumes the value implements Comparable.

A null value is considered as the minimum value.
Parameters:
  index - which column to compare. If -1, Listitem.getValueis used.
Parameters:
  ascending - whether to sort as ascending (or descending).
Parameters:
  ignoreCase - whether to sort case-insensitive
Parameters:
  byValue - whether to compare Listcell.getValue.If false, it compares Listcell.getLabel.If true, it assumes the value returned by Listcell.getValueimplements Comparable.It is ignored if the index is -1.

ListitemComparator

public ListitemComparator(int index, boolean ascending, boolean ignoreCase, boolean byValue, boolean nullAsMax)(Code)

Compares with the column of the specified index.

0 for the first column, 1 for the second and so on

Note: -1 for Listitem.getValue and it assumes the value implements Comparable.
Parameters:
  index - which column to compare. If -1, Listitem.getValueis used.
Parameters:
  ascending - whether to sort as ascending (or descending).
Parameters:
  ignoreCase - whether to sort case-insensitive
Parameters:
  byValue - whether to compare Listcell.getValue.If false, it compares Listcell.getLabel.If true, it assumes the value returned by Listcell.getValueimplements Comparable.It is ignored if the index is -1.
Parameters:
  nullAsMax - whether to consider null as the maximum value.If false, null is considered as the minimum value.

ListitemComparator

public ListitemComparator(Listheader header, boolean ascending, boolean ignoreCase)(Code)

Compares with the column which the list header is at.

Note: it compares the returned value of Listcell.getLabel . If you want to compare Listcell.getValue ., use ListitemComparator.ListitemComparator(Listheader,boolean,boolean,boolean) instead.

A null value is considered as the minimum value.
Parameters:
ascending - whether to sort as ascending (or descending).
