FloatFacetResultsHandler

public FloatFacetResultsHandler(TaxonomyReader taxonomyReader,

Method Detail

valueOf

protected final double valueOf(int ordinal)

Description copied from class: DepthOneFacetResultsHandler

Returnt the value of the requested ordinal. Called once for the result root.

Specified by:

valueOf in class DepthOneFacetResultsHandler

addSiblings

protected final int addSiblings(int ordinal,
                                int[] siblings,
                                PriorityQueue<FacetResultNode> pq)

Description copied from class: DepthOneFacetResultsHandler

Add the siblings of ordinal to the given PriorityQueue. The given PriorityQueue is already filled with sentinel objects, so implementations are encouraged to use PriorityQueue.top() and PriorityQueue.updateTop() for best performance.

addSiblings in class DepthOneFacetResultsHandler

addSiblings

protected final void addSiblings(int ordinal,
                                 int[] siblings,
                                 ArrayList<FacetResultNode> nodes)
                          throws IOException

Description copied from class: DepthOneFacetResultsHandler

Add the siblings of ordinal to the given list. This is called whenever the number of results is too high (> taxonomy size), instead of adding them to a PriorityQueue.

Specified by:

addSiblings in class DepthOneFacetResultsHandler

Throws:

IOException
