Detailed Description

The Tensor3 class.

This is a Tensor3View that also allocates storage automatically, and deallocates it when it is destroyed. We take all the functionality from Tensor3View. Additionally defined here are:

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

Constructor & Destructor Documentation

◆ Tensor3() [1/5]

Tensor3::Tensor3 ( )

Default constructor.

Definition at line 760 of file matpackIII.cc.

◆ Tensor3() [2/5]

Tensor3::Tensor3 ( Index  p,
Index  r,
Index  c 
)

Constructor setting size.

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

Definition at line 771 of file matpackIII.cc.

◆ Tensor3() [3/5]

Tensor3::Tensor3 ( Index  p,
Index  r,
Index  c,
Numeric  fill 
)

Constructor setting size and filling with constant value.

Definition at line 781 of file matpackIII.cc.

References ConstTensor3View::mdata.

◆ Tensor3() [4/5]

Tensor3::Tensor3 ( const ConstTensor3View m)

Copy constructor from Tensor3View.

This automatically sets the size and copies the data.

Definition at line 796 of file matpackIII.cc.

References ConstTensor3View::begin(), Tensor3View::begin(), copy(), and ConstTensor3View::end().

◆ Tensor3() [5/5]

Tensor3::Tensor3 ( const Tensor3 m)

Copy constructor from Tensor3.

This automatically sets the size and copies the data.

Definition at line 807 of file matpackIII.cc.

References Tensor3View::begin(), copy(), and Tensor3View::end().

◆ ~Tensor3()

Tensor3::~Tensor3 ( )
virtual

Destructor for Tensor3.

This is important, since Tensor3 uses new to allocate storage.

Definition at line 902 of file matpackIII.cc.

References ConstTensor3View::mdata.

Member Function Documentation

◆ operator=() [1/2]

Tensor3 & Tensor3::operator= ( Tensor3  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.

Assignment operators are not inherited.
