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.

◆ VectorView() [5/7]

VectorView::VectorView ( )

protecteddefault

◆ VectorView() [6/7]

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 276 of file matpackI.cc.

◆ VectorView() [7/7]

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

[in]	*data	The actual data.
[in]	p	Previous range.
[in]	n	New Range.

◆ operator=() [1/5]

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 1612 of file matpackI.cc.

References ARTS_ASSERT, begin(), Constant::e, Range::mextent, ConstVectorView::mrange, and v.

◆ operator=() [2/5]

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.

◆ 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 175 of file matpackI.cc.

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

◆ operator=() [4/5]

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 164 of file matpackI.cc.

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

◆ operator=() [5/5]

VectorView & VectorView::operator= ( Numeric x )

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

Definition at line 186 of file matpackI.cc.

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

◆ operator[]() [1/2]

VectorView VectorView::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.

Definition at line 140 of file matpackI.cc.

◆ operator[]() [2/2]

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

inline

Plain Index operator.

Definition at line 684 of file matpackI.h.
