Examples of org.clapper.util.text.XStringBuffer

org.clapper.util.text.XStringBuffer
An XStringBuffer objects wraps a standard Java StringBuffer object, providing a superset of StringBuffer's functionality. (XStringBuffer cannot actually subclass StringBuffer, since StringBuffer 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. (StringBuffer 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. (StringBuffer 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 XStringBuffer wraps a StringBuffer, it is thread-safe, but it can also be slower than a StringBuilder. For applications or methods that don't have to worry about thread safety, consider using the {@link XStringBuilder} class, instead. @see java.lang.StringBuffer @see XStringBuilder @version $Revision$ @author Copyright © 2004-2007 Brian M.
