Class ExtensibleFilter

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'

    • 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.
