- com.jidesoft.comparator.AlphanumComparator

All Implemented Interfaces:

java.util.Comparator<java.lang.CharSequence>
```
public class AlphanumComparator
extends java.lang.Object
implements java.util.Comparator<java.lang.CharSequence>
```
This is an updated version from the same named class from http://www.davekoelle.com/alphanum.html. The enhancement JIDE did to this class is
- 1. Use JDK 5 generic to support CharSequence
- 2. Add support to case insensitive comparison.

    compare in interface java.util.Comparator<java.lang.CharSequence>
  - isCaseSensitive
```
public boolean isCaseSensitive()
```
    Checks if the case is sensitive when comparing.
    
    Returns:
    
    true if the comparator is case sensitive.
  - setCaseSensitive
```
public void setCaseSensitive(boolean caseSensitive)
```
    Sets the case sensitive flag. By default, it's true meaning the comparator is case sensitive.
    
    Parameters:
