Subject Re: StringBuffer Factory?
Date Sun, 28 Dec 2003 02:23:52 GMT
While you might gain some speed, you would gain more simplicity by providing 
a good guess on how large your StringBuffer needs to be on StringBuffer 
instantiation. Most of the wasted time in using StringBuffer is done when the 
(internal) buffer is too small and needs reallocated to twice its existing 
size and the copy of data to the new buffer.
