Java regex (to me) unexpected behaviour -

इस सवाल का पहले से ही एक उत्तर है: < / P>

  • 1 उत्तर

मेरे पास निम्न जावा कोड है : 

  पैटर्न p = Pattern.compile ("#। *,", पैटर्न। DOTALL); Matcher m = p.matcher ("# $ 0: = डिफ़ॉल्ट के साथ युक्ति (एक्स, वाई) {{\ \ system.out.println (x + y); \ n}};"); जबकि (m.find ()) {System.out.println ("मिला:" + m.group () + "।"); }

और मुझे मिल रहा है: 

  मिला: # $ 0: = डिफ़ॉल्ट के साथ युक्ति (एक्स, वाई) {{System.out.println (x + वाई); }} ;.

वही जो मुझे चाहिए लेकिन उपरोक्त पैटर्न से मुझे यह उम्मीद है कि यह # और पहले सेमीकोलन के बीच कुछ भी मैच करे, न कि पिछले एक I.e., मैं इसे $ 0: = Spec (x, y) को डिफ़ॉल्ट {{System.out.println (x + y) से मिलान करने की अपेक्षा करता हूं; । यह कैसे पिछले सेमीकोलन से मेल खाता है 

  पैटर्न p = Pattern.compile (" #। * ?; ", पैटर्न। DOTALL);  *   *   के बाद  *  जोड़कर अपना प्रतिमान न लालच करें
अधिकतम कर सकते हैं।

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...
