Class CommonPattern

java.lang.Object

net.yacy.cora.util.CommonPattern

public class CommonPattern
extends java.lang.Object

This class provides Pattern constants to be used to replace a regex in s.split(regex) method calls. Because s.split(regex) causes an execution of Pattern.compile(regex).split(s, 0), it is wise to pre-compile all regex to a pattern p. Therefore do the following: transform your code into Pattern p = Pattern.compile(regex); p.split(s); The compilation of a specific pattern should be done only once. Therefore this class provides Pattern objects for the most common regex Strings. The same applies to s.replaceall(regex, replacement) which is equal to Pattern.compile(regex).matcher(s).replaceAll(replacement);
