static class: Pattern.Node [javadoc | source]

java.lang.Object
   java.util.regex.Pattern$Node

Base class for all node classes. Subclasses should override the match() method as appropriate. This class is an accepting node, so its match() always returns true.

Field Summary
Node	next

Constructor:
Node() { next = Pattern.accept; }

Method from java.util.regex.Pattern$Node Summary:
match, study

Methods from java.lang.Object:
clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait

Method from java.util.regex.Pattern$Node Detail:
boolean match(Matcher matcher, int i, CharSequence seq) { matcher.last = i; matcher.groups[0] = matcher.first; matcher.groups[1] = matcher.last; return true; } This method implements the classic accept node.
boolean study(TreeInfo info) { if (next != null) { return next.study(info); } else { return info.deterministic; } } This method is good for all zero length assertions.

Method from java.util.regex.Pattern$Node Detail:

 boolean match(Matcher matcher,
    int i,
    CharSequence seq) {
            matcher.last = i;
            matcher.groups[0] = matcher.first;
            matcher.groups[1] = matcher.last;
            return true;
}

This method implements the classic accept node.

 boolean study(TreeInfo info) {
            if (next != null) {
                return next.study(info);
            } else {
                return info.deterministic;
            }
}

This method is good for all zero length assertions.
