Detailed Description

The Tensor4 class.

This is a Tensor4View that also allocates storage automatically, and deallocates it when it is destroyed. We take all the functionality from Tensor4View. Additionally defined here are:

  1. Constructors and destructor.
  2. Assignment operators.
  3. Resize function.

Constructor & Destructor Documentation

◆ Tensor4() [1/5]

Tensor4::Tensor4 ( )

Default constructor.

Definition at line 1297 of file matpackIV.cc.

◆ Tensor4() [2/5]

Tensor4::Tensor4 ( Index  b,
Index  p,
Index  r,
Index  c 
)

Constructor setting size.

This constructor has to set the strides in the book, page and row ranges correctly!

Definition at line 1308 of file matpackIV.cc.

◆ Tensor4() [3/5]

Tensor4::Tensor4 ( Index  b,
Index  p,
Index  r,
Index  c,
Numeric  fill 
)

Constructor setting size and filling with constant value.

Definition at line 1319 of file matpackIV.cc.

References ConstTensor4View::mdata.

◆ Tensor4() [4/5]

Tensor4::Tensor4 ( const ConstTensor4View m)

Copy constructor from Tensor4View.

This automatically sets the size and copies the data.

Definition at line 1335 of file matpackIV.cc.

References ConstTensor4View::begin(), Tensor4View::begin(), copy(), and ConstTensor4View::end().

◆ Tensor4() [5/5]

Tensor4::Tensor4 ( const Tensor4 m)

Copy constructor from Tensor4.

This automatically sets the size and copies the data.

Definition at line 1347 of file matpackIV.cc.

References Tensor4View::begin(), copy(), and Tensor4View::end().

◆ ~Tensor4()

Tensor4::~Tensor4 ( )
virtual

Destructor for Tensor4.

This is important, since Tensor4 uses new to allocate storage.

Definition at line 1450 of file matpackIV.cc.

References ConstTensor4View::mdata.

Member Function Documentation

◆ operator=() [1/2]

Tensor4 & Tensor4::operator= ( Tensor4  x)

Assignment operator from another tensor.

While dimensions of views can not be adjusted, dimensions of tensors can be adjusted. Hence, the behavior of the assignment operator is different.

In this case the size of the target is automatically adjusted. This is important, so that structures containing tensors are copied correctly.

This is a deviation from the old ARTS paradigm that sizes must match exactly before copying!

Note: It is sufficient to have only this one version of the assignment (Tensor = Tensor). It implicitly covers the cases Tensor=TensorView, etc, because there is a default constructor for Tensor from TensorView. (See C++ Primer Plus, page 571ff.)

Parameters
mThe other tensor to assign to this one.
Returns
This tensor, by tradition.

◆ operator=() [2/2]

Tensor4 & Tensor4::operator= ( Numeric  x)

Assignment operator from scalar.

Assignment operators are not inherited.
