Class Checksum
extends Object
Base for checksum algorithms.
Class summary
| add data/Data -> none | |
|---|---|
| add data/Data from/int -> none | |
| add data/Data from/int to/int -> none | Adds the data to the data to be checksummed. |
| get -> ByteArray | Computes the checksum from the added data. |
| clone -> Checksum | Clones the internal state so we can compute checksums of multiple data with the same prefix. |
| operator == other/any -> bool | Whether this object is equal to the other. |
| stringify -> string | Stringifies this object. |
Methods
Clones the internal state so we can compute checksums of multiple data with the same prefix.
Whether this object is equal to the other.
Inheritance
Classes overwrite this operator to get an equality specific to their needs. Equality operators often compare the type and field contents. For example:
class Pin:
number/int
constructor .number:
operator == other:
if other is not Pin: return false
return number == other.number
A class doesn't have to follow the above format, but it must keep the operator in sync with any
hash-code method. That is, if a class has a hash-code member, then the equality and hash-code must agree. If two instances are equal (a == b), then their hash codes must also be equal (a.hash-code == b.hash-code).
