- ## Method Details

  - ### setPattern

    void setPattern​(String pattern) throws BuildException
    Set the regexp pattern from the String description.
    Parameters:
      `pattern` - the pattern to match
    Throws:
      `BuildException` - on error

  - ### getPattern

    String getPattern() throws BuildException
    Get a String representation of the regexp pattern
    Returns:
      the pattern
    Throws:
      `BuildException` - on error

  - ### matches

    boolean matches​(String argument) throws BuildException
    Does the given argument match the pattern?
    Parameters:
      `argument` - the string to match against
    Returns:
      true if the pattern matches
    Throws:
      `BuildException` - on error

  - ### getGroups

    Vector<String> getGroups​(String argument) throws BuildException
    Returns a Vector of matched groups found in the argument using default options.

    Group 0 will be the full match, the rest are the parenthesized subexpressions

    .
    Parameters:
      `argument` - the string to match against
    Returns:

    Throws:
      `BuildException` - on error

  - ### getGroups

    Vector<String> getGroups​(String input, int options) throws BuildException
    Get the match groups from this regular expression. The return type of the elements is always String.
    Parameters:
      `input` - The string to check for a match
      `options` - The list of options for the match. See the MATCH_ constants above.
    Returns:
