#include <itkFixedArray.h>

Detailed Description

template<typename TValue, unsigned int VLength = 3>
class itk::FixedArray< TValue, VLength >

Simulate a standard C array with copy semantics.

Simulates a standard C array, except that copy semantics are used instead of reference semantics. Also, arrays of different sizes cannot be assigned to one another, and size information is known for function returns.

Template Parameters

TValue	Element type stored at each location in the array.
VLength	= Length of the array.

The length of the array is fixed at compile time. If you wish to specify the length of the array at run-time, use the class itk::Array. If you wish to change to change the length of the array at run-time, you're best off using std::vector<>.

Constructor & Destructor Documentation

◆ FixedArray() [1/6]

template<typename TValue, unsigned int VLength = 3>

itk::FixedArray< TValue, VLength >::FixedArray ( )

default

Default-constructor.

Note: The other five "special member functions" are defaulted implicitly, following the C++ "Rule of Zero".

◆ FixedArray() [2/6]

template<typename TValue, unsigned int VLength = 3>

itk::FixedArray< TValue, VLength >::FixedArray ( const ValueType r[VLength] )

◆ FixedArray() [3/6]

template<typename TValue, unsigned int VLength = 3>
