Recordsets

Recordsets are tabular data encapsulations: a set of named fields with the same number of rows of data. Only simple data types can be stored in recordsets. For tabular data storage of complex data types, an array of structures should be used. Because some of the languages supported by WDDX are not case-sensitive, no two field names can differ only by their case. In the case where two fields have the same names or differ only by their case the final deserialized values will be the values from the last field. Field names must satisfy the regular expression [_A-Za-z]* where the ’.’ stands for a period, not ‘any character’.

 rows = []
 rows << [6, "MacBook Pro", 2000]
 rows << [10, "MacPro", 2200]
 rs = WDDX::RecordSet.new(["qty", "name", "price"], rows)
 WDDX.dump(rs)

Or

 rs = WDDX::RecordSet.new(["qty", "name", "price"])
 rs << [6, "MacBook Pro", 2000]
 puts rs.size # => 1
