Detailed Description

The Tensor3View class.

This contains the main implementation of a Tensor3. It defines the concepts of Tensor3View. Plus additionally the recursive subrange operator, which makes it possible to create a Tensor3View from a subrange of a Tensor3View.

The class Tensor3 is just a special case of a Tensor3View which also allocates storage.

Constructor & Destructor Documentation

◆ Tensor3View() [1/5]

constexpr Tensor3View::Tensor3View ( const Tensor3View )
constexprdefault

◆ ~Tensor3View()

virtual Tensor3View::~Tensor3View ( )
virtualdefault

Destructor.

◆ Tensor3View() [2/5]

Tensor3View::Tensor3View ( const MatrixView a)

Special constructor to make a Tensor3 view of a matrix.

Definition at line 490 of file matpackIII.cc.

◆ Tensor3View() [3/5]

Tensor3View::Tensor3View ( )
protecteddefault

◆ Tensor3View() [4/5]

Tensor3View::Tensor3View ( Numeric data,
const Range pr,
const Range rr,
const Range cr 
)
protected

Explicit constructor.

This one is used by Tensor3 to initialize its own Tensor3View part. The row range rr must have a stride to account for the length of one row.

Definition at line 499 of file matpackIII.cc.

◆ Tensor3View() [5/5]

Tensor3View::Tensor3View ( Numeric data,
const Range pp,
const Range pr,
const Range pc,
const Range np,
const Range nr,
const Range nc 
)
protected

Recursive constructor.

This is used to construct SubMatrices from SubMatrices. That means that the new ranges have to be interpreted relative to the original ranges.

The new ranges 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.
ppPrevious range.
prPrevious range.
pcPrevious range.
npNew Range.
nrNew Range.
ncNew Range.

◆ get() [1/2]

Numeric& Tensor3View::get ( Index  p,

◆ get_c_array() [1/2]

Numeric * Tensor3View::get_c_array ( )

Conversion to plain C-array.

This function returns a pointer to the raw data. It fails if the Tensor3View is not pointing to the beginning of a Tensor3 or the stride is not 1 because the caller expects to get a C array with continuous data.

Definition at line 305 of file matpackIII.cc.

◆ get_c_array() [2/2]

const Numeric * Tensor3View::get_c_array ( ) const

Conversion to plain C-array.

This function returns a pointer to the raw data. It fails if the Tensor3View is not pointing to the beginning of a Tensor3 or the stride is not 1 because the caller expects to get a C array with continuous data.

◆ operator=() [1/4]

Tensor3View & Tensor3View::operator= ( const ConstTensor3View m)

Assignment operator.

This copies the data from another Tensor3View to this Tensor3View. Dimensions must agree! Resizing would destroy the selection that we might have done in this Tensor3View by setting its range.

References begin(), ConstTensor3View::begin(), copy(), ConstTensor3View::end(), ConstTensor3View::mcr, Range::mextent, ConstTensor3View::mpr, and ConstTensor3View::mrr.

◆ operator=() [2/4]

Tensor3View & Tensor3View::operator= ( const Tensor3 m)

Assignment from a Tensor3.

This must exist to overide the automatically generated assignment operators, which don't copy the contents!

Definition at line 375 of file matpackIII.cc.

References begin(), copy(), end(), ConstTensor3View::mcr, Range::mextent, ConstTensor3View::mpr, and ConstTensor3View::mrr.

◆ operator=() [3/4]

Tensor3View & Tensor3View::operator= ( const Tensor3View m)

Assignment from Tensor3View to Tensor3View.

This is a tricky one. The problem is that since Tensor3View is derived from ConstTensor3View, 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 362 of file matpackIII.cc.

References begin(), copy(), end(), ConstTensor3View::mcr, Range::mextent, ConstTensor3View::mpr, and ConstTensor3View::mrr.
