Detailed Description

template<typename ValueType>
class BALL::TRegularData1D< ValueType >

A class to store regularaly spaced data. This class can is intended to hold regularly spaced, one-dimensional data sets. It might be useful to hold data sets like spectra, or precomputed function values.

The two bounds (set with setBoundaries ) designate an X-range with getSize equally spaced values. The data can be accessed in the same way as data of an STL vector (i.e., using operator [] and iterators).

This class fulfills the STL Container and Unary Function requirements.

const

Function operator. This operator allows the use of a TRegularData1D instance as a unary function. As required by the STL Unary Function concept, the argument x is required to be within the correct range.

Note

No range checking is done. For a more robust version, please use getData.

Definition at line 186 of file regularData1D.h.

template<typename ValueType>

void BALL::TRegularData1D< ValueType >::rescale

(

const IndexType &

new_size

)

Rescale the data. Keep the current boundaries of the data and reinterpolate the data to reflect the new size. To create a data set of new_size data points, the data is interpolated linearly at the new data points from the closest points in the old data set.

Parameters

new_size

the new data set size

Exceptions

Exception::OutOfMemory

if the memory for the resized grid could not be allocated

Definition at line 718 of file regularData1D.h.

template<typename ValueType>

void BALL::TRegularData1D< ValueType >::resize

(

const IndexType &

size

)

Resize the data. If new_size is larger than the current size, the data vector is extended to the new size and filled with default constructed items of type ValueType. Resizing to a value lesser than the current size truncates the vector.

The boundaries are adapted and the positions of the retained items fixed, i.e. the dimension is increased or decreased proportionally while the origin remains unchanged.

Parameters

new_size

the new size

Exceptions

Exception::OutOfMemory

if the memory for the resized grid could not be allocated

Definition at line 695 of file regularData1D.h.

template<typename ValueType>

BALL_INLINE void BALL::TRegularData1D< ValueType >::setDimension ( const CoordinateType &  dimension )

inline

Set the dimension of the data. This will affect neither the origin of the data, nor the number of elements stored (in contrast to resize() ). It will just store the appropriate scaling factor and affect the spacing.

Definition at line 289 of file regularData1D.h.

template<typename ValueType>
