Class FacetBuilder

java.lang.Object
  com.facetmap.simple.FacetBuilder

public class FacetBuilder
extends java.lang.Object

Accepts repeated input of values that represent Headings mapped to Resources, and spits out Facet data containing the appropriate Headings. The type and structure of the output Facet can (in future releases) be controlled by properties, but the default behavior is for parseResourceHeadingValue(String) to be somewhat intelligent about the type of Facet desired.

For example, if only numbers are input, a SpectrumFacet will be created. If only Dates are input, a DateFacet will be created. A mixture of input types usually results in a TaxonomyFacet.

To create a CompoundHeadingFacet (thus allowing multiple headings from a facet to be set on a resource), you must explicitly call allowCompoundHeadings, as it is not possible to determine this information from input headings.
