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:
Slice
struct Employee {
long number;
string firstName;
string lastName;
};
The Python mapping generates the following definition for this structure:
Python
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.
