WORK AROUND



Name: krT82822			Date: 08/11/99


An application programmer can write a class similar to
StringBuffer that isn't synchronized, but it can't be integrated
with the String class the way that StringBuffer is.  In
particular, once the buffer contains a character array that
should be turned into a String, a constructor must be called that
will create a new character array and copy all the characters
rather than using the existing character array.

EVALUATION

Could be done but it requires changing the way that Strings and StringBuffers handle their underlying array hand-off.

Such a class could significantly improve the performance of Java code that
concatenates strings, which is a very frequent operation.  See the Comments
for details.  Such a core class could be used directly by the compiler to
handle generation of code for the string concatenation operator.

This is a fairly easy way to get significant performance improvements in 
the platform without any changes to user source code.  Our working name 
for this feature is

    java.lang.UnsynchronizedStringBuffer.

I'm adding this as a Tiger feature.

With the removal of String/StringBuffer sharing in Tiger, this should be possible.
