Class BiMultiMap<K>

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, java.util.Map<K,​java.lang.Object>
    public class BiMultiMap<K>
extends java.util.HashMap<K,​java.lang.Object>
    Extension of HashMap that provides two main features. Firstly it allows reverse lookup for a key given a value, by storing a second HashMap internally which maps values to keys. Secondly, it supports Collection values, in which case, each item in the collection is used as a key in the internal reverse HashMap. It's therefore up to the caller to ensure the overall set of values, and collection values, are unique.

    Used by GeoJsonRenderer to store GeoJsonFeature instances mapped to corresponding Marker, Polyline, and Polygon map objects. We want to look these up in reverse to provide access to GeoJsonFeature instances when map objects are clicked.
