Detailed Description

template<typename T>
class iolink::ArrayX< T >

A multi dimensionnal array.

This class should not be used as is, you must use its aliases or it will not work. The current aliases are:

• Arrayi8
• Arrayi16
• Arrayi32
• Arrayi64
• Arrayu8
• Arrayu16
• Arrayu32
• Arrayu64
• Arrayf
• Arrayd

Template Parameters

T	The type of element stored in the array.

Examples

serializationArray.cpp.

Constructor & Destructor Documentation

ArrayX() [1/2]

template<typename T >

iolink::ArrayX< T >::ArrayX ( const VectorXu64 &  shape )

explicit

Create an array with the given shape.

The memory layout of the array will be the default one used by IOLink, the Fortran one, in wich the leftmost dimension is the continuous one.

Parameters

shape

The shape of the array.

ArrayX() [2/2]

template<typename T >

iolink::ArrayX< T >::ArrayX ( const Indexer &  indexer )

explicit

Create an array with a memory layout fitting the given indexer.

Parameters

indexer

the Indexer instance describing the mmeory layout.

Member Function Documentation

at()

template<typename T >

T iolink::ArrayX< T >::at

(

const VectorXu64 &

index

)

const

Get an element of the array.

Warning

If Array has an empty shape (dimension count = 0), this method has an undefined behavior.

Parameters

index

The index of the element to get.

reshape()

template<typename T >

void iolink::ArrayX< T >::reshape

(

const VectorXu64 &

shape

)

Change the shape of the array.

Parameters

shape

The new shape.

setAt()

template<typename T >

void iolink::ArrayX< T >::setAt	(	const VectorXu64 &	index,
		T	value
	)

Set a value to an element of the array.

Warning

If Array has an empty shape (dimension count = 0), this method has an undefined behavior.

Parameters

index	The index of the element to set.
value	The value to set at the given index.

Examples

serializationArray.cpp.
