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.

Definition at line 133 of file regularData1D.h.

template<typename ValueType >
BALL_INLINE ValueType BALL::TRegularData1D< ValueType >::operator() ( const CoordinateType x  )  const [inline]

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. A more robust (range-checking) version of this operator is implemented as getInterpolatedValue .

Definition at line 679 of file regularData1D.h.

template<typename ValueType>

template<typename ValueType>
ValueType& BALL::TRegularData1D< ValueType >::operator[] ( const IndexType index  )  [inline]

Mutable random access operator.

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

template<typename ValueType>
const ValueType& BALL::TRegularData1D< ValueType >::operator[] ( const IndexType index  )  const [inline]

Constant random access operator.

Note:

Definition at line 180 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
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
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>
BALL_INLINE void BALL::TRegularData1D< ValueType >::setOrigin ( const CoordinateType origin  )  [inline]

Set the origin of the data.
