      • setUseDateCache

        public void setUseDateCache(int column,
                           boolean b)
        Caches the last Date returned by ResultSet.getDate(column), and returns that same object on the next call to ResultSet.getDate(column) if the value returned from the database is identical. This also works for repeated calls to ResultSet.getDate(column) when the ResultSet has not changed rows.
      • setUseDateCache

        public void setUseDateCache(java.lang.String column,
                           boolean b)
        You know you want this, if you're going to be calling getDate() a lot.
      • setUseTimeCache

        public void setUseTimeCache(int column,
                           boolean b)
        Caches the last Time returned by ResultSet.getTime(column), and returns that same object on the next call to ResultSet.getTime(column) if the value returned from the database is identical. This also works for repeated calls to ResultSet.getTime(column) when the ResultSet has not changed rows.
      • setUseTimeCache

        public void setUseTimeCache(java.lang.String column,
                           boolean b)
        You know you want this, if you're going to be calling getTime() a lot.
      • setUseStringCache

        public void setUseStringCache(int column,
                             boolean b)
        Caches all unique Strings returned by ResultSet.getString(column). Any subsequent call to ResultSet.getString(column) will attempt to return a previously cached object if the value returned from the database matches something in the cache. This also works for repeated calls to ResultSet.getString(column) when the ResultSet has not changed rows. Note this will cache *ALL* Strings for this column, so unless you know your column values will only ever be a finite set, you should also call setCacheLastOnly() and use an ORDER BY clause.
      • setUseStringCache

        public void setUseStringCache(java.lang.String column,
                             boolean b)
        You know you want this, if you're going to be calling getString() a lot.
      • setCacheLastOnly

        public void setCacheLastOnly(int column,
                            boolean b)
        Caches the last String returned by ResultSet.getString(column), and returns that same object on the next call to ResultSet.getString(column) if the value returned from the database is identical. This also works for repeated calls to ResultSet.getString(column) when the ResultSet has not changed rows. This setting only takes effect if setUseStringCache() was called with a value of true for this column.
      • setCacheLastOnly

        public void setCacheLastOnly(java.lang.String column,
                            boolean b)
