Detailed Description

template<typename ValueType>
class BALL::TRegularData2D< ValueType >

Two-dimensional grid class. This class represents a two-dimensional array. An instance of ValueType will be created for each point of the grid upon instantiation of TRegularData2D.

This class fulfills the STL Container and Unary Function requirements. Iteration is along the x-axis first, then along the y-axis.

Definition at line 147 of file regularData2D.h.

template<typename ValueType>
BALL_INLINE ValueType BALL::TRegularData2D< ValueType >::operator() ( const CoordinateType x) 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. A more robust (range-checking) version of this operator is implemented as getInterpolatedValue .

Definition at line 806 of file regularData2D.h.

template<typename ValueType>
BALL_INLINE TRegularData2D< ValueType > & BALL::TRegularData2D< ValueType >::operator= ( const TRegularData2D< ValueType > &  data)

Assignment operator. Copy the data, the origin, and the dimension (spacing is copied implicitly as well).

Exceptions
Exception::OutOfMemoryif the memory for the copy could not be allocated

Definition at line 516 of file regularData2D.h.

template<typename ValueType>
bool BALL::TRegularData2D< ValueType >::operator== ( const TRegularData2D< ValueType > &  data) const

Equality operator. Two grids are equal if they have the same number of points in all two dimensions, same origin, spacing and the data fields are equal.

Definition at line 946 of file regularData2D.h.

template<typename ValueType>
const ValueType& BALL::TRegularData2D< ValueType >::operator[] ( const IndexType index) const
inline

Nonmutable random access operator.

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

Definition at line 224 of file regularData2D.h.

template<typename ValueType>
void BALL::TRegularData2D< 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_sizethe new data set size
Exceptions
Exception::OutOfMemoryif the memory for the resized grid could not be allocated

Definition at line 544 of file regularData2D.h.

template<typename ValueType>
void BALL::TRegularData2D< ValueType >::resize ( const IndexType new_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_sizethe new size
Exceptions
Exception::OutOfMemoryif the memory for the resized grid could not be allocated

Definition at line 595 of file regularData2D.h.

template<typename ValueType>
void BALL::TRegularData2D< 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 scling factor and affect the spacing.

Definition at line 307 of file regularData2D.h.

Set the origin of the data.
