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

.

Parameters:

argument - the string to match against

Returns:

the vector of groups

Throws:

BuildException - on error

getGroups

Vector 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:

the vector of groups

Throws:

BuildException - on error

getPattern

String getPattern()

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

matches

boolean matches(String input,
                int options)
         throws BuildException

Does this regular expression match the input, given certain options

Parameters:

input - The string to check for a match

options - The list of options for the match. See the MATCH_ constants above.

Returns:

true if the pattern matches
