　　Java 库的建立方法及其实例（6）

接下来，看看Matcher类。这个类实现了MatchResult interface. 看看MatchResult的定义：

[games]$javap -classpath .. -s jregex.MatchResult

Compiled from jregex/MatchResult.java

public interface jregex.MatchResult

/* ACC_SUPER bit NOT set */

{

public static final int MATCH;

/* I */

public static final int PREFIX;

/* I */

public static final int SUFFIX;

/* I */

public static final int TARGET;

/* I */

public abstract jregex.Pattern pattern();

/* ()Ljregex/Pattern; */

public abstract int groupCount();

/* ()I */

public abstract boolean isCaptured();

/* ()Z */

public abstract boolean isCaptured(int);

/* (I)Z */

public abstract boolean isCaptured(java.lang.String);

/* (Ljava/lang/String;)Z */

public abstract java.lang.String group(int);

/* (I)Ljava/lang/String; */

public abstract boolean getGroup(int, java.lang.StringBuffer);

/* (ILjava/lang/StringBuffer;)Z */

public abstract boolean getGroup(int, jregex.TextBuffer);

/* (ILjregex/TextBuffer;)Z */

public abstract java.lang.String group(java.lang.String);
