********************************************************************
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
================
.. doxygenclass:: rocprim::texture_cache_iterator
:members:
