- Parameters
-
index | Access index. The index has to be in the range . |
- Returns
- The resulting value.
- Exceptions
-
std::out_of_range | Invalid vector access index. |
◆ begin()
template<typename VT , bool TF>
Returns an iterator to the first non-zero element of the sparse vector.
- Returns
- Iterator to the first non-zero element of the sparse vector.
◆ canAlias()
template<typename VT , bool TF>
template<typename T >
Returns whether the expression can alias with the given address alias.
- Parameters
-
alias | The alias to be checked. |
- Returns
- true in case the expression can alias, false otherwise.
◆ canSMPAssign()
template<typename VT , bool TF>
Returns whether the expression can be used in SMP assignments.
- Returns
- true in case the expression can be used in SMP assignments, false if not.
◆ end()
template<typename VT , bool TF>
Returns an iterator just past the last non-zero element of the sparse vector.
- Returns
- Iterator just past the last non-zero element of the sparse vector.
◆ find()
template<typename VT , bool TF>
Searches for a specific vector element.
- Parameters
-
index | The index of the search element. |
- Returns
- Iterator to the element in case the index is found, end() iterator otherwise.
◆ isAliased()
template<typename VT , bool TF>
template<typename T >
Returns whether the expression is aliased with the given address alias.
- Parameters
-
alias | The alias to be checked. |
- Returns
- true in case an alias effect is detected, false otherwise.
◆ lowerBound()
template<typename VT , bool TF>
Returns an iterator to the first index not less then the given index.
- Parameters
-
index | The index of the search element. |

- Iterator to the first index not less then the given index, end() iterator otherwise.
◆ nonZeros()
template<typename VT , bool TF>
Returns the number of non-zero elements in the sparse vector.
- Returns
- The number of non-zero elements in the sparse vector.
◆ operand()
template<typename VT , bool TF>
Returns the sparse vector operand.
- Returns
- The sparse vector operand.
◆ operator*() [1/2]
|
constexprnoexceptinherited |
CRTP-based conversion operation for constant vectors.
- Returns
- Const reference of the actual type of the vector.
This operator performs the CRTP-based type-safe downcast to the actual type VT of the vector. It will return a constant reference to the actual type VT.
◆ operator*() [2/2]
|
constexprnoexceptinherited |
CRTP-based conversion operation for non-constant vectors.
- Returns
- Mutable reference of the actual type of the vector.
This operator performs the CRTP-based type-safe downcast to the actual type VT of the vector. It will return a mutable reference to the actual type VT.
◆ operator[]()
template<typename VT , bool TF>
Subscript operator for the direct access to the vector elements.
- Parameters
-
index | Access index. The index has to be in the range . |
- Returns
- The resulting value.
◆ operator~() [1/2]
|
constexprnoexceptinherited |
CRTP-based conversion operation for constant vectors.
- Returns
- Constant reference of the actual type of the vector.
This operator performs the CRTP-based type-safe downcast to the actual type VT of the vector. It will return a constant reference to the actual type VT.
◆ operator~() [2/2]
|
constexprnoexceptinherited |
CRTP-based conversion operation for non-constant vectors.
- Returns
- Mutable reference of the actual type of the vector.
This operator performs the CRTP-based type-safe downcast to the actual type VT of the vector. It will return a mutable reference to the actual type VT.
◆ size()
template<typename VT , bool TF>
Returns the current size/dimension of the vector.
- Returns
- The size of the vector.
◆ upperBound()
template<typename VT , bool TF>
Returns an iterator to the first index greater then the given index.
- Parameters
-
index | The index of the search element. |
- Returns
- Iterator to the first index greater then the given index, end() iterator otherwise.
◆ useAssign
template<typename VT , bool TF>
Compilation switch for the serial evaluation strategy of the transposition expression.
The useAssign compile time constant expression represents a compilation switch for the serial evaluation strategy of the transposition expression. In case the given sparse vector expression of type VT requires an intermediate evaluation, useAssign will be set to 1 and the transposition expression will be evaluated via the assign function family. Otherwise useAssign will be set to 0 and the expression will be evaluated via the subscript operator.
