Member Function Documentation

gmx_ana_poscalc_t * gmx::PositionCalculationCollection::Impl::createCalculation ( e_poscalc_t  type,
int  flags 

Creates a new position calculation.

[in]typeType of calculation.
[in]flagsFlags for setting calculation options (see documentation of the flags).

Does not throw currently, but may throw std::bad_alloc in the future.

This method contains the actual implementation of the similarly named method in the parent class.

ArrayRef<const int> gmx::PositionCalculationCollection::Impl::getFrameIndices ( int  size,
int  index[] 

Maps given topology indices into frame indices.

Only one position calculation at a time needs to access this (and there are also other thread-unsafe constructs here), so a temporary array is used to avoid repeated memory allocation.

void gmx::PositionCalculationCollection::Impl::insertCalculation ( gmx_ana_poscalc_t pc,
gmx_ana_poscalc_t before 

Inserts a position calculation structure into its collection.

pcData structure to insert.
beforeData structure before which to insert (NULL = insert at end).

Inserts pc to its collection before before. If before is NULL, pc is appended to the list.

void gmx::PositionCalculationCollection::Impl::removeCalculation ( gmx_ana_poscalc_t pc)

Removes a position calculation structure from its collection.

pcData structure to remove.

Removes pc from its collection.

Member Data Documentation

const gmx_mtop_t* gmx::PositionCalculationCollection::Impl::top_

Topology data.

Can be NULL if none of the calculations require topology data or if setTopology() has not been called.
