Here is the definition of our EmployeeMap
once more:
dictionary<long, Employee> EmployeeMap; |
As for sequences, the Ruby mapping does not create a separate named type for this definition. Instead, all dictionaries are simply instances of Ruby's hash collection type. For example:
em = {} e = Employee.new e.number = 31 e.firstName = "James" e.lastName = "Gosling" em[e.number] = e |
The Ice run time validates the elements of a dictionary to ensure that they are compatible with the declared type; a TypeError
exception is raised if an incompatible type is encountered.
