Constructor Detail

ListRowComparator

public ListRowComparator(DialogObjectConstant column,
                         int initialPriority)

Creates a new ListRowComparator that will use values in the specified column when comparing rows. Note that the column attribute must implement the Comparable interface.

Parameters:

column - column used when comparing rows

initialPriority - the initial priority of this list row comparator

Throws:

IllegalArgumentException - if column does not contain a Comparable attribute type

ListRowComparator

public ListRowComparator(DialogObjectConstant column,
                         int initialPriority,
                         ListRowComparator.Sorting sortDirection)

Creates a new ListRowComparator that will use values in the specified column when comparing rows. Note that the column attribute must implement the Comparable interface.

Parameters:

column - column used when comparing rows

initialPriority - the initial priority of this list row comparator

sortDirection - the initial sort direction of this list row comparator

Throws:

IllegalArgumentException - if column does not contain a Comparable attribute type

Method Detail

toggleSorting

public void toggleSorting()
