ConcurrentParallelIndexExecutor

public class ConcurrentParallelIndexExecutor implements ParallelIndexExecutor(Code)

Executes the indexing process using sevearl threads based on the partitioned list of index entities.

By default (with maxThreads set to -1) creates N threads during the indexing process where N is the number of partitioned index entities groups (one therad per group). If maxThreads is set to a positive integer number, the index executor will use it as the number of threads to create, regardless of the number of partitioned entities groups. author: kimchy

Constructor Summary
public	ConcurrentParallelIndexExecutor() Constructs a new concurrent index executor with `maxThreads` defaults to -1.
public	ConcurrentParallelIndexExecutor(int maxThreads) Constructs a new concurrent index executor with the given max threads.

Method Summary
public void	performIndex(IndexEntity[][] entities, IndexEntitiesIndexer indexEntitiesIndexer, CompassGpsInterfaceDevice compassGps) Performs the indexing process using the provided index entities indexer.

Constructor Detail

ConcurrentParallelIndexExecutor
public ConcurrentParallelIndexExecutor()(Code)
	Constructs a new concurrent index executor with `maxThreads` defaults to -1.

ConcurrentParallelIndexExecutor
public ConcurrentParallelIndexExecutor(int maxThreads)(Code)
	Constructs a new concurrent index executor with the given max threads. Parameters: maxThreads - The number of threads to use or -1 for dynamic threads

Method Detail

performIndex
public void performIndex(IndexEntity[][] entities, IndexEntitiesIndexer indexEntitiesIndexer, CompassGpsInterfaceDevice compassGps)(Code)
	Performs the indexing process using the provided index entities indexer. Creates a pool of N threads (if `maxThreads` is set to -1, N is the numer of entities groups, otherwise N is the number of `maxThreads`). Parameters: entities - The partitioned index entities groups and index entities to index Parameters: indexEntitiesIndexer - The entities indexer to use Parameters: compassGps - Compass gps interface for meta information
