Class ObjectFloatHashMap<K>

  • Type Parameters:
    K - any Object type
    All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, java.util.Map<K,​float[]>
    public class ObjectFloatHashMap<K>
extends java.util.HashMap<K,​float[]>
    This class is a map which binds key Object to float value.

    This class is NOT thread safe, synchronize read and write operation when used in multi-threaded context if you really need features provided by this collection.
    In multithreaded context, it may be wiser to use alternative thread safe and type safe collection such as ConcurrentHashMap<YourType, Float>.

      • remove

        public float[] remove​(java.lang.Object key)
        Specified by:
        remove in interface java.util.Map<K,​float[]>
        Overrides:
        remove in class java.util.HashMap<K,​float[]>

      • clear

        public void clear()
        Specified by:
        clear in interface java.util.Map<K,​float[]>
        Overrides:
        clear in class java.util.HashMap<K,​float[]>

      • put

        public void put​(K key,
                float value)
        Associates the specified value with the specified key in this map. If the map previously contained a mapping for this key, the old value is replaced.
        Parameters:
        key - key with which the specified value is to be associated.
        value - value to be associated with the specified key.

      • getFloat

        public float getFloat​(K key,
                      float defaultValue)
        Return the float value associated with given object, or the given default value if object is not in this map.
        Parameters:
        key - the object from which to get associated value
        defaultValue - the default value to use if object not present.
        Returns:
        float value associated to object

      • getMax

        public float getMax()
        Return maximum value stored in this map.
        Returns:
        maximum float value
