Class SimpleFacetSpace

java.lang.Object
  com.facetmap.simple.SimpleFacetSpace

All Implemented Interfaces:

FacetSpace

Direct Known Subclasses:

MutableSimpleFacetSpace, SqlFacetSpace

public class SimpleFacetSpace
extends java.lang.Object
implements FacetSpace

A mutable Vector-based FacetSpace. This object changes on the fly whenever the addFacet() method is used. Selection refs generated before such a change may not be valid after the change.

Field Summary

protected java.util.Hashtable	facetHash Indexes facets by name.
protected java.util.Vector	facets Indexes facets by number.
protected int	version

Constructor Summary

SimpleFacetSpace()
Create an empty but valid SimpleFacetSpace.

Method Summary

void	addFacet(Facet facet)
CompoundHeadingFacet	getCompoundHeadingFacet(java.lang.String id) Returns the CompoundHeadingFacet with the given identifier.
DateFacet	getDateFacet(java.lang.String id) Returns the DateFacet with the given identifier.
Facet	getFacet(int index) Returns the Facet at the given index.
Facet	getFacet(java.lang.String id) Returns the Facet with the given identifier.
int	getFacetCount() Returns the number of Facets in this FacetSpace.
java.util.List	getFacets() Returns an immutable list of Facets in this FacetSpace.
GeographyFacet	getGeographyFacet(java.lang.String id) Returns the GeographyFacet with the given identifier.
KeywordFacet	getKeywordFacet(java.lang.String id) Returns the KeywordFacet with the given identifier.
SpectrumFacet	getSpectrumFacet(java.lang.String id) Returns the SpectrumFacet with the given identifier.
protected TaxonomyFacet	getTaxonomy(int index)
TaxonomyFacet	getTaxonomyFacet(java.lang.String id) Returns the TaxonomyFacet with the given identifier.
java.lang.String	getVersion() Returns zero -- version is not supported by this implementation.
int	indexOf(Facet t) Returns the index number of the dimension the Facet occupies.

Field Detail

facets

protected java.util.Vector facets

Indexes facets by number.

facetHash

protected java.util.Hashtable facetHash

Indexes facets by name. If a taxonomy has no name, the name is its index number in the Vector.

version

protected int version
