      • MapFeatures

        public MapFeatures​(int initialCapacity)
        Constructs a MapFeatures instance.
        Parameters:
        initialCapacity - The implementation performs internal sizing to accommodate this many elements.
        Throws:
        java.lang.IllegalArgumentException - if the initial capacity of elements is negative

        public MapFeatures​(java.util.Map<? extends java.lang.String,​? extends java.lang.String> m)
        Constructs a MapFeatures instance.
        Parameters:
        m - the map

      • MapFeatures

        public MapFeatures​(int initialCapacity,
                   float loadFactor)
        Constructs a MapFeatures instance.
        Parameters:
        initialCapacity - the initial capacity. The implementation performs internal sizing to accommodate this many elements, given the specified load factor.
        loadFactor - the load factor (table density) for establishing the initial table size
        Throws:
        java.lang.IllegalArgumentException - if the initial capacity of elements is negative or the load factor is nonpositive

                   float loadFactor,
                   int concurrencyLevel)
        Constructs a MapFeatures.
        Parameters:
        initialCapacity - the initial capacity. The implementation performs internal sizing to accommodate this many elements, given the specified load factor.
        loadFactor - the load factor (table density) for establishing the initial table size
        concurrencyLevel - the estimated number of concurrently updating threads. The implementation may use this value as a sizing hint.
        Throws:
        java.lang.IllegalArgumentException - if the initial capacity is negative or the load factor or concurrencyLevel are nonpositive
