Detailed Description

Cluster data which keeps history about changes

The algorithm doesn't work on this data. Instead the PndFTSCASliceData is created from this.

int PndFTSCAClusterData::RowNumber ( int  index ) const

inline

Return the row number/index of the given cluster.

Definition at line 129 of file PndFTSCAClusterData.h.

References fData.

{ assert( index < static_cast<int>( fData.size() ) ); return fData[index].fRow; }

int PndFTSCAClusterData::RowOffset ( unsigned int  rowIndex ) const

inline

Return the index of the first cluster in the given row.

Supports calls with rowIndex greater than the available number of rows. In that case it returns NumberOfClusters.

To iterate over the clusters in one row do:

* PndFTSCAClusterData cd;
* const int lastClusterIndex = cd.RowOffset( rowIndex + 1 );
* for ( int hitIndex = cd.RowOffset( rowIndex ); hitIndex < lastClusterIndex; ++hitIndex )
*

float PndFTSCAClusterData::X ( int  index ) const
