a doubt icloneable interface petshop 4.0?


in 'dbutility' digest petshop 4.0,the summary category sqlhelper slight 'getcachedparameters':



        open stationary sqlparameter[] getcachedparameters(string cachekey) {
        sqlparameter[] cachedparms = (sqlparameter[])parmcache[cachekey];

        (cachedparms == null)
            relapse null;

        sqlparameter[] clonedparms = new sqlparameter[cachedparms.length];

        (int i = 0, j = cachedparms.length; i < j; i++)
            clonedparms[i] = (sqlparameter)((icloneable)cachedparms[i]).clone();

        relapse clonedparms;
    }


why relapse 'cachedparms' directly ?
