Class WildcardFileFilter

    java.lang.Object
      org.apache.commons.io.filefilter.AbstractFileFilter
          org.apache.commons.io.filefilter.WildcardFileFilter

All Implemented Interfaces:
  FileFilter, FilenameFilter, Serializable, IOFileFilter

    public class WildcardFileFilter

extends AbstractFileFilter
implements Serializable

Filters files using the supplied wildcards.

This filter selects files and directories based on one or more wildcards. Testing is case-sensitive by default, but this can be configured.

The wildcard matcher uses the characters '?' and '*' to represent a single or multiple wildcard characters. This is the same as often found on Dos/Unix command lines. The extension check is case-sensitive by . See `FilenameUtils.wildcardMatchOnSystem(java.lang.String, java.lang.String)` for more information.

For example:

     File dir = new File(".");
     FileFilter fileFilter = new WildcardFileFilter("*test*.java~*~");
     File[] files = dir.listFiles(fileFilter);
     for (int i = 0; i < files.length; i++) {
       System.out.println(files[i]);
     }

  Construct a new wildcard filter for a single wildcard specifying case-sensitivity.

  Parameters:
    `wildcard` - the wildcard to match, not null
    `caseSensitivity` - how to handle case sensitivity, null means case-sensitive

    `IllegalArgumentException` - if the pattern is null

### WildcardFileFilter

    public WildcardFileFilter(String[] wildcards)

  Construct a new case-sensitive wildcard filter for an array of wildcards.

  The array is not cloned, so could be changed after constructing the instance. This would be inadvisable however.

  Parameters:
    `wildcards` - the array of wildcards to match, not null
