Iterators

Constant

.. doxygenclass:: rocprim::constant_iterator
   :members:

Note

For example, constant_iterator(20) generates the infinite sequence:

20
20
20
...

Counting

.. doxygenclass:: rocprim::counting_iterator
   :members:

Note

For example, counting_iterator(20) generates the infinite sequence:

20
21
22
23
...

Transform

.. doxygenclass:: rocprim::transform_iterator
   :members:

Note

transform_iterator(sequence, transform) should generate the sequence:

transform(sequence(0))
transform(sequence(1))
...

Predicate

.. doxygenclass:: rocprim::predicate_iterator
   :members:

Note

predicate_iterator(sequence, test, predicate) generates the sequence:

predicate(test[0]) ? sequence[0] : default
predicate(test[1]) ? sequence[1] : default
predicate(test[2]) ? sequence[2] : default
...

Pairing Values with Indices

.. doxygenclass:: rocprim::arg_index_iterator
   :members:

Note

arg_index_iterator(sequence) generates the sequence of tuples:

(0, sequence[0])
(1, sequence[1])
...

Zip

.. doxygenclass:: rocprim::zip_iterator
   :members:

Note

zip_iterator(sequence_X, sequence_Y) generates the sequence of tuples:

(sequence_X[0], sequence_Y[0])
(sequence_X[1], sequence_Y[1])
...

Discard

.. doxygenclass:: rocprim::discard_iterator
   :members:

Texture Cache
