/**
* The MatchActionProcessor class provides AWK-like line by line filtering
* of a text stream, pattern action pair association, and field splitting
* based on a registered separator. However, the class can be used with
* any compatible PatternMatcher/PatternCompiler implementations and
* need not use the AWK matching classes in org.apache.oro.text.awk. In fact,
* the default matcher and compiler used by the class are Perl5Matcher and
* Perl5Compiler from org.apache.oro.text.regex.
* <p>
* To completely understand how to use MatchActionProcessor, you should first
* look at {@link MatchAction} and {@link MatchActionInfo}.
* A MatchActionProcessor is first initialized with
* the desired PatternCompiler and PatternMatcher instances to use to compile
* patterns and perform matches. Then, optionally, a field separator may
* be registered with {@link #setFieldSeparator setFieldSeparator()}
* Finally, as many pattern action pairs as desired are registerd with
* {@link #addAction addAction()} before processing the input
* with {@link #processMatches processMatches()}. Pattern action
* pairs are processed in the order they were registered.
* <p>
* The look of added actions can closely mirror that of AWK when anonymous
* classes are used. Here's an example of how you might use
* MatchActionProcessor to extract only the second column of a semicolon
* delimited file:
* <p>
* <pre>
* import java.io.*;
*
* import org.apache.oro.text.*;
* import org.apache.oro.text.regex.*;
*
* public final class semicolon {
*
* public static final void main(String[] args) {
* MatchActionProcessor processor = new MatchActionProcessor();
*
* try {
* processor.setFieldSeparator(";");
* // Using a null pattern means to perform the action for every line.
* processor.addAction(null, new MatchAction() {
* public void processMatch(MatchActionInfo info) {
* // We assume the second column exists
* info.output.println(info.fields.elementAt(1));
* }
* });
* } catch(MalformedPatternException e) {
* e.printStackTrace();
* System.exit(1);
* }
*
* try {
* processor.processMatches(System.in, System.out);
* } catch(IOException e) {
* e.printStackTrace();
* System.exit(1);
* }
* }
*}
* </pre>
* You can redirect the following sample input to stdin to test the code:
* <pre>
* 1;Trenton;New Jersey
* 2;Annapolis;Maryland
* 3;Austin;Texas
* 4;Richmond;Virginia
* 5;Harrisburg;Pennsylvania
* 6;Honolulu;Hawaii
* 7;Santa Fe;New Mexico
