Examples of org.apache.oro.text.regex.PatternCompiler

org.apache.oro.text.regex.PatternCompiler
ialization of compiler, matcher, and input omitted; try { pattern = compiler.compile("\\d+"); } catch(MalformedPatternException e) { System.out.println("Bad pattern."); System.out.println(e.getMessage()); System.exit(1); } if(matcher.matches(input, pattern)) System.out.println(input + " is a number"); else System.out.println(input + " is not a number");
Specific PatternCompiler implementations such as Perl5Compiler may have variations of the compile() methods that take extra options affecting the compilation of a pattern. However, the PatternCompiler method implementations should provide the default behavior of the class. @version @version@ @since 1.0 @see Pattern @see PatternMatcher @see MalformedPatternException
