    public FilenameSelector()

- ## Method Details

  - ### toString

    public String toString()
    Description copied from class: `DataType`
    Basic DataType toString().
    Overrides:
      `toString` in class `DataType`
    Returns:
      a string describing this object

  - ### setName

    public void setName(String pattern)
    The name of the file, or the pattern for the name, that should be used for selection.
    Parameters:
      `pattern` - the file pattern that any filename must match against in order to be selected.

  - ### setRegex

    public void setRegex(String pattern)
    The regular expression the file name will be matched against.
    Parameters:
      `pattern` - the regular expression that any filename must match against in order to be selected.

  - ### setCasesensitive

    public void setCasesensitive(boolean casesensitive)
    Whether to ignore case when checking filenames.
    Parameters:
      `casesensitive` - whether to pay attention to case sensitivity

  - ### setNegate

    public void setNegate(boolean negated)
    You can optionally reverse the selection of this selector, thereby emulating an <exclude> tag, by setting the attribute negate to true. This is identical to surrounding the selector with <not></not>.
    Parameters:
      `negated` - whether to negate this selection

  - ### setParameters

    public void setParameters(Parameter... parameters)
    When using this as a custom selector, this method will be called. It translates each parameter into the appropriate setXXX() call.
    Specified by:
      `setParameters` in interface `Parameterizable`
    Overrides:
      `setParameters` in class `BaseExtendSelector`
    Parameters:
      `parameters` - the complete set of parameters for this selector

  - ### verifySettings

    public void verifySettings()
    Checks to make sure all settings are kosher. In this case, it means that the name attribute has been set.
    Overrides:
      `verifySettings` in class `BaseSelector`

  - ### isSelected

    public boolean isSelected(File basedir, String filename, File file)
    The heart of the matter. This is where the selector gets to decide on the inclusion of a file in a particular fileset. Most of the work for this selector is offloaded into SelectorUtils, a static class that provides the same services for both FilenameSelector and DirectoryScanner.
    Specified by:
      `isSelected` in interface `FileSelector`
    Specified by:
      `isSelected` in class `BaseExtendSelector`
    Parameters:
      `basedir` - the base directory the scan is being done from
      `filename` - is the name of the file to check
      `file` - is a java.io.File object the selector can use
    Returns:
      whether the file should be selected or not
