Class FacetLabel

  • All Implemented Interfaces:

    public class FacetLabel
    extends Object
    implements Comparable<FacetLabel>
    Holds a sequence of string components, specifying the hierarchical name of a category.
    NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.

        Constant Field Values
      • components

        public final String[] components
        The components of this FacetLabel. Note that this array may be shared with other FacetLabel instances, e.g. as a result of subpath(int), therefore you should traverse the array up to length for this path's components.
      • length

        public final int length
        The number of components of this FacetLabel.
    • Constructor Detail

      • FacetLabel

        public FacetLabel​(String... components)
        Construct from the given path components.
      • FacetLabel

        public FacetLabel​(String dim,
                          String[] path)
        Construct from the dimension plus the given path components.
    • Method Detail

      • hashCode

        public int hashCode()
        hashCode in class Object
      • longHashCode

        public long longHashCode()
        Calculate a 64-bit hash function for this path. This is necessary for NameHashIntCacheLRU (the default cache impl for LruTaxonomyWriterCache) to reduce the chance of "silent but deadly" collisions.
      • subpath

        public FacetLabel subpath​(int length)
        Returns a sub-path of this path up to length components.
      • toString

        public String toString()
        Returns a string representation of the path.
