Examples of XStringBuilder

org.clapper.util.text.XStringBuilder
An XStringBuilder objects wraps a standard Java StringBuilder object, providing a superset of StringBuilder's functionality. (XStringBuilder cannot actually subclass StringBuilder, since StringBuilder is final.) Among the additional methods that this class provides are:
- A set of {@link #split()} methods, to split the contents of thebuffer on a delimiter
- A {@link #delete(String) delete()} method that deletes the firstoccurrence of a substring. (StringBuilder only provides a delete() method that takes a starting and ending index.)
- A {@link #replace(String,String) replace()} method that replacesthe first occurrence of a substring. (StringBuilder only provides a replace() method that takes a starting and ending index.)
- A {@link #replaceAll(String,String) replaceAll()} method toreplace all occurrences of a substring with something else
- Methods to encode and decode metacharacter sequences in place. (See {@link #encodeMetacharacters()} and{@link #decodeMetacharacters()}.)
Because XStringBuilder wraps a StringBuilder, it is not thread-safe; but, it is likely to be faster than a StringBuffer or an XStringBuffer. For applications or methods that must to worry about multiple threads modifying the buffer concurrently, consider using the {@link XStringBuffer} class, instead. @see java.lang.StringBuilder @see XStringBuffer @version $Revision$ @author Copyright © 2004-2007 Brian M.
