  - ### toString

    public String toString()
    Description copied from class: `DataType`
    Basic DataType toString().

    Returns:
      a string describing this object

  - ### setText

    public void setText(String contains)

    The encoding of the resources processed
    Parameters:
      `encoding` - encoding of the resources processed
    Since:
      Ant 1.9.0

    Whether to ignore case in the string being searched.
    Parameters:
      `casesensitive` - whether to pay attention to case sensitivity

  - ### setIgnorewhitespace

    public void setIgnorewhitespace(boolean ignorewhitespace)
    Whether to ignore whitespace in the string being searched.

    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.

    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:

    public boolean isSelected(Resource r)
    The heart of the matter. This is where the selector gets to decide on the inclusion of a Resource.
    Specified by:
      `isSelected` in interface `FileSelector`
    Specified by:
      `isSelected` in interface `ResourceSelector`
    Parameters:
      `r` - the Resource to check.
    Returns:
      whether the Resource is selected.
