Examples of org.apache.oro.text.perl.Perl5Util.match()

org.apache.oro.text.perl.Perl5Util.match()
Searches for the first pattern match somewhere in a character array taking a pattern specified in Perl5 native format:
```
 [m]/pattern/[i][m][s][x] 
```
The m prefix is optional and the meaning of the optional trailing options are:

i
case insensitive match
m
treat the input as consisting of multiple lines
s
treat the input as consisting of a single line
x
enable extended expression syntax incorporating whitespace and comments
As with Perl, any non-alphanumeric character can be used in lieu of the slashes.
If the input contains the pattern, the org.apache.oro.text.regex.MatchResult can be obtained by calling {@link #getMatch()}. However, Perl5Util implements the MatchResult interface as a wrapper around the last MatchResult found, so you can call its methods to access match information.
@param pattern The pattern to search for. @param input The char[] input to search. @return True if the input contains the pattern, false otherwise. @exception MalformedPerl5PatternException If there is an error inthe pattern. You are not forced to catch this exception because it is derived from RuntimeException.
