Method Detail

printProgressAndEstimation

default void printProgressAndEstimation(int currNumComputation,
                                        String descriptionStr,
                                        int totNumComputations,
                                        long currTime,
                                        String compType,
                                        int stepsMade,
                                        long passedTime)

Prints the progress of the current computation, either with or without a retriever.

Parameters:

currNumComputation - the number of the current computation

descriptionStr - the descriptive text of this computation step

totNumComputations - the total number of computations

currTime - the current time in milliseconds

compType - the type of computation to print

stepsMade - the number of steps made

passedTime - the already passed time in milliseconds

computeSimilarities

long computeSimilarities(DecimalFormat df,
                         WriteableObjectPool queryPool,
                         WriteableObjectPool casePool,
                         AbstractSimilarityCacheMatrix similarityMatrix)

Computes the similarities according to the strategy. Thereby, the implementation should use the given methods of this interface to enable printing of the progress and utilizing the cache functionality.

Parameters:

df - the decimal format to use

queryPool - Pool of queries

casePool - Pool of cases

similarityMatrix - the similarity matrix to fill

Returns:

the overall time the procedure ran
