Primitive Types
Some methods use primitive types for inputs.
- 
                        int - a 32-bit signed, two's complement integer value. 
- 
                        long - a 64-bit signed, two's complement integer value. 
- 
                        float - a 32-bit floating point number. 
- 
                        double - a 64-bit floating point number. 
- 
                        string - a text string of unicode characters. 
- 
                        boolean - true or false. 
- 
                        date - a representation of a date and time. The SOAP implementation is an xsd:dateTime. The dateTime is specified in the following form " YYYY-MM-DDThh:mm:ssZ" where:- 
                              YYYYindicates the year
- 
                              MMindicates the month
- 
                              DDindicates the day
- 
                              Tindicates the start of the required time section
- 
                              hhindicates the hour
- 
                              mmindicates the minute
- 
                              ssindicates the second
- 
                              (optional) adding a Zbehind the time indicates UTC timezone. All times on the library are in UTC by default.
 A sample dateTime would be " 2016-10-31T15:30:10Z". Details are language-specific once the Web Services Description Language (WSDL) has been transformed into a specific language.
