Python HashMap.maybe_set Examples

Example #1

File: test_hashmap.py Project: davy9233/pytopojson

    def test_hashmap_can_set_an_object_by_key_if_not_already_set(self):
        map = HashMap(10, hash, equal)
        key = {'hash': 1}

        self.assertEqual(map.maybe_set(key, 42), 42)
        self.assertEqual(map.get(key), 42)
        self.assertEqual(map.maybe_set(key, 43), 42)
        self.assertEqual(map.get(key), 42)

Example #2

File: join.py Project: davy9233/pytopojson

    def index(self):
        index_by_point = HashMap(len(self.coordinates) * 1.4, self.hash_index, self.equal_index, Int32Array, -1, Int32Array)
        indexes = Int32Array(len(self.coordinates))

        for i in range(len(self.coordinates)):
            tmp = index_by_point.maybe_set(i, i)
            indexes[i] = tmp

        return indexes
