Internally, all data is adminstered with primitive data types for performance reasons. Externally, all classes offer a great deal of functionality and convenience.
The general convention for all classes is the following:
Operations can be performed using two sets of methods. To multiply,
for example, two instances A and B of a
class, you may either call
C = A.times(B) or C.assignTimes(A,B)
to store the result in C. In the first case, a new
instance is created, in the latter this is avoided.
All operations follow this convention, and data types mix:
To multiply and instance A with a double d
A = A.times(d) or A.assignTimes(d)
Entries can be accessed using set- and
get-methods and various data types.
