  - ### toString

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

  - ### setExpression

    public void setExpression(String theexpression)
    The regular expression used to search the file.
    Parameters:
      `theexpression` - this must match a line in the file to be selected.

  - ### setCaseSensitive

    public void setCaseSensitive(boolean b)
    Whether to ignore case or not.
    Parameters:
      `b` - if false, ignore case.
    Since:
      Ant 1.8.2

  - ### setMultiLine

    public void setMultiLine(boolean b)
    Whether to match should be multiline.
    Parameters:
      `b` - the value to set.
    Since:
      Ant 1.8.2

  - ### setSingleLine

    public void setSingleLine(boolean b)
    Whether to treat input as singleline ('.' matches newline). Corresponds to java.util.regex.Pattern.DOTALL.
    Parameters:
      `b` - the value to set.
    Since:
      Ant 1.8.2

  - ### 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.
