Adding subreports to master report at runtime (java) -

-

OK, I did not get an answer to my question with Google ...

Currently I I am using JSPPR Ramps and Dynamic Jasks to create and print my reports. When I just use a Jasper-file or jrxml-files, all the work is fine. I have a piece of code that merged all Jasper print files in one if I need to combine the report Ho. However, it is not really optimal ...

Can I use a .jasper or .jrxml-file as a master report (this includes a header, a footer and an empty description- Band) and fill it with its extension-band with 1-N subreports (currently .jasper or .jxrml)?

Currently only one uses my demographic datasheet (tablemodel) and receives its data from other general criteria parameters.

I have found many different ways to do something that can eliminate a result which I want but no success yet ... Which builders / managers / What do I need? It is a little frustrating because there is not enough information about different classes, methods and their criteria, why they are and what is necessary do not explain enough examples ...

Do I have a DynamicJasperHelper DynamicReportBuilder should be used to create DynamicReport that generates JasperReport which is replenished with the JasperFillManager.fillReport method?

Report all sub to a main report and print for visibility when expression to say that is the sub-portal code. 

  & lt; Subreport & gt; & Lt; Report Element UUID = "9f36c3cb-7e29-4040-a14e-6a 91775e89e4" X = "0" y = "35" width = "555" height = "47" & gt; & Lt; PrintWhenExpression & gt; & Lt ;! [CDATA [$ P {disp} == 1]] & gt; & Lt; / PrintWhenExpression & gt; & Lt; / ReportElement & gt; & Lt ;! - other element - & gt; & Lt; / Subreport & gt;

Look for the following line in the code above. 

  & lt; PrintWhenExpression & gt; & Lt ;! [CDATA [$ P {disp} == 1]] & gt; & Lt; / PrintWhenExpression & gt;

This means that the entire sub-report should be included in the entire $ P {disp} .intValue () == 1 . Here $ P {disp} is the parameter that you must pass to report to work with printWhenExpression .

Parameters or not required, you can also use a field .

Note: You can get the same perspective for all sub-reports.

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...
