Class TableComparator

java.lang.Object
  edu.jhu.tmaj.client.tables.data.TableComparator

All Implemented Interfaces:

java.util.Comparator

public final class TableComparator
extends java.lang.Object
implements java.util.Comparator

A Comparator that is used to sort rows in a JTable. This comparator could be used like: Collections.sort(dataList, new TableComparator(columnNumber)); The variable dataList represents a List of Lists representing the data in the table, such that every List represents one row. This is the Comparator that sorts the data in SortFilterFrame. The Comparator attempts to convert the values in table cells to integers and then sort by the natural ordering of integers; if this can not be done, it sorts according to the natural ordering of strings. The sorting is case insensitive.
