java.lang.Objectorg.apache.tomcat.util.buf.B2CConverter
public class B2CConverter
Efficient conversion of bytes to character . This uses the standard JDK mechansim - a reader - but provides mechanisms to recycle all the objects that are used. It is compatible with JDK1.1 and up, ( nio is better, but it's not available even in 1.2 or 1.3 ) Not used in the current code, the performance gain is not very big in the current case ( since String is created anyway ), but it will be used in a later version or after the remaining optimizations.
