Examples of com.ibm.commons.util.FastStringBuffer

com.ibm.commons.util.FastStringBuffer
Fast String buffer.
This class has almost all the methods found in the standard StringBuffer but is faster for many reasons :
- It has no synchronized methods=> don't access a buffer from differents threads!
- It cannot be shared (shared attribute does not exist)
- The memory allocation scheme is different
It also has bonus methods which are very helpful. @ibm-api
