css - How do I reselect/filter elements when I already have a jquery object? -

- 

  फ़ंक्शन initItems ($ आइटम, वर्तमान, गिनती) {$ items.removeClass ('z-item-current' ); $ Items.each (फ़ंक्शन (इंडेक्स) {var $ self = $ (this); $ self.data ('z-item-index', सूचकांक); अगर (सूचकांक === वर्तमान) {$ self.addClass (' Z-item-current z-item-show '); var pre = current - 1, next = current + 1; pre = pre & lt; 0? Count - 1: pre; next = अगला & gt; संख्या - 1? 0: AddClass ('z-item-previous z-item-show'); $ ($ आइटम [अगला]) addClass ('z-item-next z-item-show' );}}); // शोध या फ़िल्टर करें $ आइटम // यदि z-item-show class है, तो इसे दिखाएं; अन्यथा, इसे छुपाना };

ऊपर दिखाए गए कोड के रूप में, मैं एक jQuery ऑब्जेक्ट को पुनः खोज / फ़िल्टर करना चाहता हूं। विशिष्ट होने के लिए, मैं $ आइटम से $ आइटम z-item-show class और $ आइटम z-item-show class बिना विभाजित करना चाहता हूं ।

वर्तमान में, $ items.each एक दृष्टिकोण है, और $ items.parent ()। ढूँढें एक और है।

< पी> कोई अन्य दृष्टिकोण (अधिक सुरुचिपूर्ण)

आप बस का उपयोग कर सकते हैं और वस्तुओं को वर्ग या नहीं: 

  $ items.filter ('.z-item-show')। शो (); $ Items.not ( 'z-आइटम शो।') को छिपाने ()।;

यह $ items.each () से साफ है, लेकिन संभवतः कम कुशल हो, क्योंकि यह 2 loops करता है।

c++ - Cassandra datastax cpp driver - avoiding unnecessary copies -

-
I use the following method to create my insert statement for Cassandra (using datastax cpp driver) : ssStmt1 & lt; & Lt; "Insert some table (...) value (....)" string sStatement1 = ssStmt1.str (); Castestring cass1 = cass_string_init (sStatement1.c_str ()); CassStatement * pStmt1 = cass_statement_new (cass1, 0); I have also tried the following: CassString cass1 = cass_string_init ("Enter some table (id, date, c) value (? ,?,?); "); CassStatement * pStmt1 = cass_statement_new (cass1, 3); Cass_statement_bind_uuid (pStmt1, 0, uuidKey); Cass_statement_bind_int64 (PSTMT1, 1, timestamp); Cass_statement_bind_string (pStmt1, 2, sSomething); The first pattern works with mixed keys, the second is not. The key has a timestamp and a UUID. Timestamp is one of two errors in the field (based on the used bond statement). If bound in this way: cass_statement_bind_int64_by_name (pStmt1, "date", timestamp); I get the following error: Inva...
