Detailed Description

template<typename T>
class vtkDenseArray< T >

Contiguous storage for N-way arrays.

vtkDenseArray is a concrete vtkArray implementation that stores values using a contiguous block of memory. Values are stored with fortran ordering, meaning that if you iterated over the memory block, the left-most coordinates would vary the fastest.

In addition to the retrieval and update methods provided by vtkTypedArray, vtkDenseArray provides methods to:

Fill the entire array with a specific value.

Retrieve a pointer to the storage memory block.

template<typename T>
bool vtkDenseArray< T >::IsDense ( )
overridevirtual

Returns true iff the underlying array storage is "dense", i.e.

that GetSize() and GetNonNullSize() will always return the same value. If not, the array is "sparse".

Implements vtkArray.

template<typename T>
const vtkArrayExtents& vtkDenseArray< T >::GetExtents ( )
overridevirtual

Returns the extents (the number of dimensions and size along each dimension) of the array.

Implements vtkArray.

template<typename T>
SizeT vtkDenseArray< T >::GetNonNullSize ( )
overridevirtual

Returns the number of non-null values stored in the array.

Note that this value will equal GetSize() for dense arrays, and will be less-than-or-equal to GetSize() for sparse arrays.

Implements vtkArray.

template<typename T>
void vtkDenseArray< T >::GetCoordinatesN ( const SizeT  n,
vtkArrayCoordinates coordinates 
)
overridevirtual

Returns the coordinates of the n-th value in the array, where n is in the range [0, GetNonNullSize()).

Note that the order in which coordinates are visited is undefined, but is guaranteed to match the order in which values are visited using vtkTypedArray::GetValueN() and vtkTypedArray::SetValueN().

Implements vtkArray.

template<typename T>
vtkArray* vtkDenseArray< T >::DeepCopy ( )
overridevirtual

Returns a new array that is a deep copy of this array.

Implements vtkArray.

template<typename T>

overridevirtual

Returns the value stored in the array at the given coordinates.

Note that the number of dimensions in the supplied coordinates must match the number of dimensions in the array.

Implements vtkTypedArray< T >.

template<typename T>

CoordinateT  j 
)
overridevirtual

Returns the value stored in the array at the given coordinates.

Note that the number of dimensions in the supplied coordinates must match the number of dimensions in the array.

Implements vtkTypedArray< T >.

template<typename T>
const T& vtkDenseArray< T >::GetValueN ( const SizeT  n)
overridevirtual

Returns the n-th value stored in the array, where n is in the range [0, GetNonNullSize()).

This is useful for efficiently visiting every value in the array. Note that the order in which values are visited is undefined, but is guaranteed to match the order used by vtkArray::GetCoordinatesN().

Implements vtkTypedArray< T >.

template<typename T>
void vtkDenseArray< T >::SetValue ( CoordinateT  i,
const T &  value 
)
overridevirtual

Overwrites the value stored in the array at the given coordinates.

Note that the number of dimensions in the supplied coordinates must match the number of dimensions in the array.

Implements vtkTypedArray< T >.

template<typename T>
void vtkDenseArray< T >::SetValue ( CoordinateT  i,

Implements vtkTypedArray< T >.

template<typename T>
void vtkDenseArray< T >::SetValueN ( const SizeT  n,
const T &  value 
)
overridevirtual

Overwrites the n-th value stored in the array, where n is in the range [0, GetNonNullSize()).

This is useful for efficiently visiting every value in the array. Note that the order in which values are visited is undefined, but is guaranteed to match the order used by vtkArray::GetCoordinatesN().

Implements vtkTypedArray< T >.

template<typename T>
void vtkDenseArray< T >::ExternalStorage ( const vtkArrayExtents extents,
MemoryBlock storage 
)

Initializes the array to use an externally-allocated memory block.

The supplied MemoryBlock must be large enough to store extents.GetSize() values. The contents of the memory must be stored contiguously with fortran ordering,

Dimension-labels are undefined after calling ExternalStorage() - you should initialize them accordingly.

The array will use the supplied memory for storage until the array goes out of scope, is configured to use a different memory block by calling ExternalStorage() again, or is configured to use internally-allocated memory by calling Resize().

Note that the array will delete the supplied memory block when it is no longer in use. caller's responsibility to ensure that the memory does not go out-of-scope until the array has been destroyed or is no longer using it.

template<typename T>
void vtkDenseArray< T >::Fill ( const T &  value)

Fills every element in the array with the given value.

template<typename T>
T& vtkDenseArray< T >::operator[] ( const vtkArrayCoordinates coordinates)

Returns a value by-reference, which is useful for performance and code-clarity.

template<typename T>
const T* vtkDenseArray< T >::GetStorage ( ) const

Returns a read-only reference to the underlying storage.

Values are stored contiguously with fortran ordering.

template<typename T>
T* vtkDenseArray< T >::GetStorage ( )

Returns a mutable reference to the underlying storage.

Values are stored contiguously with fortran ordering. Use at your own risk!
