Detailed Description

The VectorView class.

This contains the main implementation of a vector. The class Vector 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.

Constructor & Destructor Documentation

◆ VectorView() [1/6]

VectorView::VectorView ( const Vector )

Bail out immediately if somebody tries to create a VectorView from a const Vector.

Definition at line 309 of file matpackI.cc.

◆ VectorView() [2/6]

VectorView::VectorView ( Vector v)

Create VectorView from a Vector.

Definition at line 320 of file matpackI.cc.

References ConstVectorView::mdata, and ConstVectorView::mrange.

◆ ~VectorView()

virtual VectorView::~VectorView ( )
inlinevirtual

Destructor.

Definition at line 442 of file matpackI.h.

◆ VectorView() [3/6]

VectorView::VectorView ( Numeric a)

A special constructor, which allows to make a VectorView from a scalar.

Definition at line 567 of file matpackI.cc.

◆ VectorView() [4/6]

VectorView::VectorView ( )
protected

Default constructor.

This is necessary, so that we can have a default constructor for the derived class Vector.

Definition at line 575 of file matpackI.cc.

◆ VectorView() [5/6]

VectorView::VectorView ( Numeric data,
const Range range 
)
protected

Explicit constructor.

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

Definition at line 583 of file matpackI.cc.

◆ VectorView() [6/6]

VectorView::VectorView ( Numeric 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.

const Numeric * VectorView::get_c_array ( ) const

Conversion to plain C-array.

This function returns a pointer to the raw data. It fails if the VectorView is not pointing to the beginning of a Vector or the stride is not 1 because the caller expects to get a C array with continuous data.

References ConstVectorView::begin(), ConstVectorView::end(), and ConstVectorView::nelem().

◆ operator=() [1/5]

VectorView & VectorView::operator= ( const ConstVectorView v)

Assignment operator.

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

Definition at line 378 of file matpackI.cc.

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

Referenced by Vector::operator=().

◆ operator=() [2/5]

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

Assignment from VectorView to VectorView.

This is a tricky one. The problem is that since VectorView is derived from ConstVectorView, 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 395 of file matpackI.cc.

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

◆ operator=() [3/5]

VectorView & VectorView::operator= ( const Vector v)

Assignment from Vector.

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

Definition at line 409 of file matpackI.cc.

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

◆ operator=() [4/5]

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

Assignment operator from Array<Numeric>.

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

Array<Numeric> 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 2018 of file matpackI.cc.

References MatrixView::begin(), and Array< base >::nelem().

◆ operator=() [5/5]

VectorView & VectorView::operator= ( Numeric  x)

Assigning a scalar to a VectorView will set all elements to this value.

Definition at line 423 of file matpackI.cc.

References ConstVectorView::begin(), copy(), and ConstVectorView::end().

◆ operator[]() [1/4]

Numeric VectorView::operator[] ( Index  n) const
inline

Plain const index operator.

Has to be redifined here, because the one from ConstVectorView is hidden.

Definition at line 383 of file matpackI.h.

References ConstVectorView::operator[]().

Referenced by MakeVector::MakeVector().

◆ operator[]() [2/4]

ConstVectorView VectorView::operator[] ( const Range r) const

Const 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. Has to be redifined here, because the one from ConstVectorView is hidden.

References ConstVectorView::operator[]().

◆ operator[]() [3/4]

Numeric& VectorView::operator[] ( Index  n)
