JSON format properties and data type conversions
Properties and data type conversions of the JSON format are described.
Configurable properties
The following properties can be configured.
Configurable JSON format properties Property name Explanation Possible values Default value Encoding This is the encoding that will be used in converting bytes to string and string to bytes wherever applicable. Enum All encodings
Data type conversions
JSON type system is more constrained than the XSD type system. JSON supports a value of type String, Number and Boolean. It does not support octal and hexdecimal values. The data handler will delegate all type conversions to the business object. Hence, all conversions that are supported by the business object will be supported by the data handler. We recommend that the type should match between the JSON data and the corresponding data objects but we are tolerant with certain formats as shown in the tables below.
JSON to DataObject conversions
Conversion from JSON type to DataObject type JSON/DataObject String Long Double boolean Date, datetime String Valid Valid if value is long Valid if value is double Valid if value is true or false Valid if the value is a date Long Valid Valid Valid Invalid Valid if the value is a date Double Valid Valid if value is long Valid Invalid Invalid Boolean Valid Invalid Invalid Valid Invalid For simple type lists, the types between the JSON data and the schema have to match.
For the base64Binary and hexBinary types, the business object will be converted to byte[], however this is not a JSON data supported type. JSONDataHandler will automatically convert the byte[] to a string based on the encoding information configured on the JSON format properties.
DataObject to JSON conversions
DataObject type to JSON type DataObject JSON String String Long Long Integer Long Double Double Float Double Boolean Boolean Date String Datetime String
