ucam::hifst::LocalPruningConditions Class Reference

convenience class that takes care of local pruning conditions. Conditions are indexed by 1000*cc+y, so you can search through all conditions and get to the closest set of conditions that apply. More...

Member Function Documentation

void ucam::hifst::LocalPruningConditions::add ( const conditions &  c )

inline

Add condition.

Definition at line 71 of file task.hifst.localpruningconditions.hpp.

Here is the caller graph for this function:

void ucam::hifst::LocalPruningConditions::clear ( )

inline

Clears all conditions.

Here is the caller graph for this function:

bool ucam::hifst::LocalPruningConditions::operator() ( unsigned  cc, unsigned  span, unsigned  numstates, float &  w  )

inline

Checks whether a given cell lattice at (cc,x,y) with numstates states qualifies for local pruning.

Parameters

cc	Category numerical representation for the cyk cell
span	Corresponding to y coordinate of cyk cell. Note that span=y+1
numstates	Number of states of the cell lattice (1 - 100M states)
w	If qualifies, weight for pruning will be stored here

Returns

true if qualifies, false otherwise
