ExtensibleFilter (JBoss VFS 3.3.0.Final API)

java.lang.Object
- org.jboss.vfs.util.ExtensibleFilter

All Implemented Interfaces:

VirtualFileFilter
```
public class ExtensibleFilter
extends Object
implements VirtualFileFilter
```
An extensible filter for VFS files. Three arrays are maintained for checking: a prefix, suffix, and match array. If the filename starts with any of the prefixes, ends with any of the suffixes, or exactly matches any of the matches, then the accepts method will return false.
NOTE: the arrays *must* be sorted for the string matching to work, and suffixes use the 'reverseComparator'

Constructor Detail
- ExtensibleFilter
```
public ExtensibleFilter()
```
  Use the default values for suffixes, prefixes, and matches
- ExtensibleFilter
```
public ExtensibleFilter(String[] matches,
                        String[] prefixes,
                        String[] suffixes)
```
  Create using a custom set of matches, prefixes, and suffixes. If any of these arrays are null, then the corresponding default will be substituted.
  
  Parameters:
  
  matches - the matches
  
  prefixes - the prefixes
  
  suffixes - the suffixes

accepts
```
public boolean accepts(VirtualFile file)
```
If the filename matches any string in the prefix, suffix, or matches array, return false. Perhaps a bit of overkill, but this method operates in log(n) time, where n is the size of the arrays.

Specified by:

accepts in interface VirtualFileFilter

Parameters:

file - The file to be tested

Returns:

false if the filename matches any of the prefixes, suffixes, or matches.
