Detailed Description

template<typename TValueType>
class itk::Array< TValueType >

Array class with size defined at construction time.

This class derives from the vnl_vector<> class. Its size is assigned at construction time (run time) and can not be changed afterwards except by using assignment to another Array.

The class is templated over the type of the elements.

Template parameters for class Array:

TValueType = Element type stored at each location in the array.

Constructor & Destructor Documentation

template<typename TValueType>

itk::Array< TValueType >::Array ( )

Default constructor. It is created with an empty array it has to be allocated later by assignment

template<typename TValueType>

itk::Array< TValueType >::Array ( const Array< TValueType > & )

Copy constructor. Uses VNL copy construtor with correct setting for memory management.

template<typename TValueType>

itk::Array< TValueType >::Array ( SizeValueType dimension ) [explicit]

Constructor with size. Size can only be changed by assignment

template<typename TValueType>

itk::Array< TValueType >::Array	(	ValueType *	data,
		SizeValueType	sz,
		bool	LetArrayManageMemory = `false`
	)

Constructor that initializes array with contents from a user supplied buffer. The pointer to the buffer and the length is specified. By default, the array does not manage the memory of the buffer. It merely points to that location and it is the user's responsibility to delete it. If "LetArrayManageMemory" is true, then this class will free the memory when this object is destroyed.

template<typename TValueType>

itk::Array< TValueType >::Array	(	const ValueType *	data,
		SizeValueType	sz,
		bool	LetArrayManageMemory = `false`
	)

Constructor that initializes array with contents from a user supplied buffer. The pointer to the buffer and the length is specified. By default, the array does not manage the memory of the buffer. It merely points to that location and it is the user's responsibility to delete it. If "LetArrayManageMemory" is true, then this class will free the memory when this object is destroyed.

template<typename TValueType>

template<class TArrayValue >

itk::Array< TValueType >::Array ( const Array< TArrayValue > & r ) [inline]

Constructor to initialize an array from another of any data type

Definition at line 92 of file itkArray.h.

template<typename TValueType>

itk::Array< TValueType >::~Array ( )

This destructor is not virtual for performance reasons. However, this means that subclasses cannot allocate memory.

Member Function Documentation

template<typename TValueType>

void itk::Array< TValueType >::Fill ( TValueType const & v ) [inline]

Set the all the elements of the array to the specified value

const TValueType& itk::Array< TValueType >::GetElement ( SizeValueType i ) const [inline]

Get one element

unsigned int itk::Array< TValueType >::GetNumberOfElements ( void ) const [inline]

Return the number of elements in the Array

template<typename TValueType>

const Self& itk::Array< TValueType >::operator= ( const Self & rhs )

Copy opertor

Reimplemented in itk::OptimizerParameters< TValueType >, itk::OptimizerParameters< TValueType >, and itk::OptimizerParameters< double >.

template<typename TValueType>

const Self& itk::Array< TValueType >::operator= ( const VnlVectorType & rhs )

Reimplemented in itk::OptimizerParameters< TValueType >, and itk::OptimizerParameters< double >.

template<typename TValueType>

void itk::Array< TValueType >::SetData	(	TValueType *	data,
		bool	LetArrayManageMemory = `false`
	)

Set the pointer from which the data is imported. If "LetArrayManageMemory" is false, then the application retains the responsibility of freeing the memory for this data. If "LetArrayManageMemory" is true, then this class will free the memory when this object is destroyed.

Referenced by itk::MetaArrayReader::GetOutput(), and itk::OptimizerParametersHelper< TValueType >::MoveDataPointer().

template<typename TValueType>

void itk::Array< TValueType >::SetData	(	TValueType *	data,
		SizeValueType	sz,
		bool	LetArrayManageMemory = `false`
	)

Similar to the previous method. In the above method, the size must be seperately set prior to using user-supplied data. This introduces an unnecessary allocation step to be performed. This method avoids it and should be used to import data whereever possible to avoid this. Set the pointer from which the data is imported. If "LetArrayManageMemory" is false, then the application retains the responsibility of freeing the memory for this data. If "LetArrayManageMemory" is true, then this class will free the memory when this object is destroyed.
