A Slice structure maps to a Python class with the same name. For each Slice data member, the Python class contains a corresponding attribute. For example, here is our Employee
structure once more:
struct Employee { long number; string firstName; string lastName; };
The Python mapping generates the following definition for this structure:
class Employee(object): def __init__(self, number=0, firstName='', lastName=''): self.number = number self.firstName = firstName self.lastName = lastName def __hash__(self): # ... def __eq__(self, other): # ... def __str__(self): # ...
The constructor initializes each of the attributes to a default value appropriate for its type. You can also declare different default values for members of primitive and enumerated types.
The __hash__
method returns a hash value for the structure based on the value of all its data members.
The __eq__
method returns true if all members of two structures are (recursively) equal.
The __str__
method returns a string representation of the structure.
