The IndexMatrix (a.k.a. Matrix<IndexPoint>) class is a special implementation of a Matrix with Elements of type IndexPoint.
The implementation guaranties that no data is transfered to and from the devices when using this version of the Matrix. OpenCL functionality (global ids) is used to make the IndexPoints available on the device. This implementation requires, that the Matrix is const and can, therefore, not be modified after creation.

| Matrix< IndexPoint >::value_type skelcl::Matrix< IndexPoint >::at | ( | size_type | n | ) | const |
Returns the IndexPoint at position n (i.e. n).
This version does prevent out of range accesses. If n > size() an std::out_of_range exception is thrown.
| n | The position for which the IndexPoint should be returned. |
Definition at line 110 of file IndexMatrix.cpp.
| Matrix< IndexPoint >::value_type skelcl::Matrix< IndexPoint >::back | ( | ) | const |
| void skelcl::Matrix< IndexPoint >::dataOnDeviceModified | ( | ) | const |
This function should never be called as it only exists for compatibility reasons with the Matrix class.
This function will always fail with an assertion.
Definition at line 184 of file IndexMatrix.cpp.
| void skelcl::Matrix< IndexPoint >::dataOnHostModified | ( | ) | const |
This function should never be called as it only exists for compatibility reasons with the Matrix class.
This function will always fail with an assertion.
Definition at line 189 of file IndexMatrix.cpp.
| const detail::DeviceBuffer & skelcl::Matrix< IndexPoint >::deviceBuffer | ( | const detail::Device & | device | ) | const |
This function should never be called as it only exists for compatibility reasons with the Matrix class.
This function will always fail with an assertion.

Returns a string defining functions necessary to access the Matrix on the device. For the IndexMatrix this function always returns an empty string.
This functions exists for compatibility reasons with the Matrix class.
Definition at line 150 of file IndexMatrix.cpp.
| detail::Distribution< Matrix< IndexPoint > > & skelcl::Matrix< IndexPoint >::distribution | ( | ) | const |
Returns the current distribution of the Matrix.
Definition at line 130 of file IndexMatrix.cpp.
| Matrix< IndexPoint >::value_type skelcl::Matrix< IndexPoint >::front | ( | ) | const |
Return the first IndexPoint stored in the Matrix (i.e. {0, 0}).
Definition at line 119 of file IndexMatrix.cpp.
| std::vector< IndexPoint > & skelcl::Matrix< IndexPoint >::hostBuffer | ( | ) | const |
This function should never be called as it only exists for compatibility reasons with the Matrix class.
This function will always fail with an assertion.
Definition at line 177 of file IndexMatrix.cpp.
| Matrix< IndexPoint >::value_type skelcl::Matrix< IndexPoint >::operator[] | ( | size_type | n | ) | const |
Returns the IndexPoint at position n (i.e. n).
This version does not prevent out of range accesses. If n > size() the behavior is undefined.
| n | The position for which the IndexPoint should be returned. |
Definition at line 105 of file IndexMatrix.cpp.

| void skelcl::Matrix< IndexPoint >::setDistribution | ( | std::unique_ptr< detail::Distribution< Matrix< IndexPoint >>> && | newDistribution | ) | const |
Changes the distribution of the Matrix.
| newDistribution | The new distribution to be set. After this call distribution is the new selected distribution of the Matrix. |
