Class ObjectDoubleTreeMap

  • All Implemented Interfaces:
    java.io.Serializable, java.lang.Cloneable, java.util.Map, java.util.NavigableMap, java.util.SortedMap
    public class ObjectDoubleTreeMap
extends java.util.TreeMap
    This class is a map which binds key Object to double 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, Double>.

      • put

        public void put​(java.lang.Object key,
                double 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.

      • inc

        public void inc​(java.lang.Object key,
                double quantity)
        Incremente the value associated with the specified key. If this key did not exist, it is created and the value is set to '1'.
        Parameters:
        key - key for which the specified value must be incremented.
        quantity - the quantity to increment

      • inc

        public void inc​(java.lang.Object key)
        Incremente the value associated with the specified key. If this key did not exist, it is created and the value is set to '1'.
        Parameters:
        key - key for which the specified value must be incremented.

      • getDouble

        public double getDouble​(java.lang.Object key,
                        double defaultValue)
        Returns the value to which this map maps the specified key. Returns defaultValue if the map contains no mapping for this key.
        Parameters:
        key - key whose associated value is to be returned.
        defaultValue - value to return if the map contains no mapping for this key.
        Returns:
        the value to which this map maps the specified key, or defaultValue if the map contains no mapping for this key.
