◆ canAlias()
template<typename VT1 , typename VT2 , bool TF>
template<typename T >
Returns whether the expression can alias with the given address alias.
- Parameters
-
alias | The alias to be checked. |
- Returns

◆ isAliased()
template<typename VT1 , typename VT2 , bool TF>
template<typename T >
Returns whether the expression is aliased with the given address alias.

◆ operator~() [1/2]
template<typename VT, bool TF>
Conversion operator for non-constant vectors.
- Returns

◆ operator~() [2/2]
template<typename VT, bool TF>
Conversion operator for constant vectors.
- Returns
- Const reference of the actual type of the vector.
◆ rightOperand()
template<typename VT1 , typename VT2 , bool TF>
Returns the right-hand side sparse vector operand.
- Returns
- The right-hand side sparse vector operand.
◆ size()
template<typename VT1 , typename VT2 , bool TF>
Returns the current size/dimension of the vector.
- Returns
- The size of the vector.
◆ returnExpr
template<typename VT1 , typename VT2 , bool TF>
Compilation switch for the selection of the subscript operator return type.
The returnExpr compile time constant expression is a compilation switch for the selection of the ReturnType. If either vector operand returns a temporary vector or matrix, returnExpr will be set to false and the subscript operator will return it's result by value. Otherwise returnExpr will be set to true and the subscript operator may return it's result as an expression.
