AlphanumComparator

java.lang.Object
- 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.

    Creates a case sensitive comparator to use the alphanum algorithm to compare the strings.
  - AlphanumComparator
```
public AlphanumComparator(boolean caseSensitive)
```
    Creates a comparator to use the alphanum algorithm to compare the strings.
    
    Parameters:
    
    caseSensitive - true or false.
- Method Detail
  - compare
```
public int compare(java.lang.CharSequence s1,
                   java.lang.CharSequence s2)
```
    Specified by:
    
    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:
    
    caseSensitive - true or false.
