Detailed Description

The ComplexVectorView class.

This contains the main implementation of a complex vector. The class
ComplexVector is just a special case of subvector which also allocates storage.

Unfortunately, names of element functions of derived classes hide the names of the original class, even if the arguments are different. This means that we have to redefine those element functions that can have different arguments, for example the constant index operators and iterators.

◆ ComplexVectorView() [5/7]

ComplexVectorView::ComplexVectorView ( )

Referenced by operator[]().

◆ ComplexVectorView() [6/7]

ComplexVectorView::ComplexVectorView ( Complex data,
const Range range 
)
protected

Explicit constructor.

This one is used by Vector to initialize its own VectorView part.

Definition at line 452 of file complex.cc.

◆ ComplexVectorView() [7/7]

ComplexVectorView::ComplexVectorView ( Complex data,
const Range p,
const Range n 
)
protected

Recursive constructor.

This is used to construct sub ranges from sub ranges. That means that the new range has to be interpreted relative to the original range. The new range may contain -1 for the extent which acts as a joker. However, the used Range constructor converts this to an explicit range, consistent with the original Range.

Parameters
*dataThe actual data.
pPrevious range.
nNew Range.

◆ operator=() [2/10]

ComplexVectorView & ComplexVectorView::operator= ( const Array< Complex > &  v)

Assignment operator from Array<Complex>.

This copies the data from an Array<Complex> to this VectorView. Dimensions must agree! Resizing would destroy the selection that we might have done in this VectorView by setting its range.

Array<Complex> can be useful to collect things in, because there is a .push_back method for it. Then, after collecting we usually have to transfer the content to a Vector. With this assignment operator that's easy.

Definition at line 1534 of file complex.cc.

References Range::mextent, ConstComplexVectorView::mrange, and Array< base >::nelem().

◆ operator=() [3/10]

ComplexVectorView& ComplexVectorView::operator= ( const Array< Numeric > &  v)

◆ operator=() [4/10]

ComplexVectorView & ComplexVectorView::operator= ( const ComplexVector v)

Assignment from ComplexVector.

This is important to avoid a bug when assigning a Vector to a Complex*VectorView.

Definition at line 223 of file complex.cc.

References begin(), copy(), end(), Range::mextent, and ConstComplexVectorView::mrange.

◆ operator=() [5/10]

ComplexVectorView & ComplexVectorView::operator= ( const ComplexVectorView v)

Assignment from ComplexVectorView to ComplexVectorView.

This is a tricky one. The problem is that since ComplexVectorView is derived from ConstComplexVectorView, a default = operator is generated by the compiler, which does not do what we want. So we need this one to override the default.

Definition at line 210 of file complex.cc.

References begin(), copy(), end(), Range::mextent, and ConstComplexVectorView::mrange.

◆ operator=() [6/10]

ComplexVectorView & ComplexVectorView::operator= ( const ConstComplexVectorView v)

Assignment operator.

This copies the data from another VectorView t o this Complex*VectorView. Dimensions must agree! Resizing would destroy the selection that we might have done in this VectorView by setting its range.

ComplexVectorView ComplexVectorView::operator[] ( const Range r)

Index operator for subrange.

We have to also account for the case, that *this is already a subrange of a Vector. This allows correct recursive behavior.
