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.

Member Function Documentation

operator=() [1/2]

Tensor4 & Tensor4::operator=

(

Numeric

x

)

Assignment operator from scalar.

Assignment operators are not inherited.

Definition at line 1394 of file matpackIV.cc.

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

operator=() [2/2]

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

m	The other tensor to assign to this one.

Returns

This tensor, by tradition.

References swap.

resize()

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

Resize function.

If the size is already correct this function does nothing. All data is lost after resizing! The new tensor is not initialized, so it will contain random values.
