> Class {{org.apache.hadoop.hive.serde2.io.HiveVarcharWritable}} creates a
> superfluous wrapper and then immediately unwraps it. Don't bother wrapping
> in this scenario.
> {code}
> public void set(HiveVarchar val, int len) {
> set(val.getValue(), len);
> }
> public void set(String val, int maxLength) {
> value.set(HiveBaseChar.enforceMaxLength(val, maxLength));
> }
> public HiveVarchar getHiveVarchar() {
> return new HiveVarchar(value.toString(), -1);
> }
> // Here calls getHiveVarchar() which creates a new HiveVarchar object with
> a string in it
> // The object is passed to set(HiveVarchar val, int len)
> // The string is pulled out
> public void enforceMaxLength(int maxLength) {
> // Might be possible to truncate the existing Text value, for now just do
> something simple.
> if (value.getLength()>maxLength && getCharacterLength()>maxLength)
> set(getHiveVarchar(), maxLength);
> }
