Package kieker.analysis.generic.clustering.mtree.query

Class Query<T>

java.lang.Object

kieker.analysis.generic.clustering.mtree.query.Query<T>

Type Parameters:

T - data type of the values in the query result

All Implemented Interfaces:

Iterable<ResultItem<T>>

public final class Query<T>
extends Object
implements Iterable<ResultItem<T>>

An Iterable class which can be iterated to fetch the results of a nearest-neighbors query.

The neighbors are presented in non-decreasing order from the queryData argument to the getNearest*() call.

The query on the M-Tree is executed during the iteration, as the results are fetched. It means that, by the time when the n-th result is fetched, the next result may still not be known, and the resources allocated were only the necessary to identify the n first results.

Since:

2.0.0
