Class TIntLongHash

    • Field Detail

      • _set

        public transient int[] _set
        the set of ints

      • no_entry_key

        protected int no_entry_key
        key that represents null NOTE: should not be modified after the Hash is created, but is not final because of Externalization

      • no_entry_value

        protected long no_entry_value
        value that represents null NOTE: should not be modified after the Hash is created, but is not final because of Externalization

      • consumeFreeSlot

        protected boolean consumeFreeSlot

    • Constructor Detail

      • TIntLongHash

        public TIntLongHash()
        Creates a new T#E#Hash instance with the default capacity and load factor.

      • TIntLongHash

        public TIntLongHash(int initialCapacity)
        Creates a new T#E#Hash instance whose capacity is the next highest prime above initialCapacity + 1 unless that value is already prime.
        Parameters:
        initialCapacity - an int value

      • TIntLongHash

        public TIntLongHash(int initialCapacity,
                    float loadFactor)
        Creates a new TIntLongHash instance with a prime value at or near the specified capacity and load factor.
        Parameters:
        initialCapacity - used to find a prime capacity for the table.
        loadFactor - used to calculate the threshold over which rehashing takes place.

      • TIntLongHash

        public TIntLongHash(int initialCapacity,
                    float loadFactor,
                    int no_entry_key,
                    long no_entry_value)
        Creates a new TIntLongHash instance with a prime value at or near the specified capacity and load factor.
        Parameters:
        initialCapacity - used to find a prime capacity for the table.
        loadFactor - used to calculate the threshold over which rehashing takes place.
        no_entry_value - value that represents null

    • Method Detail

      • getNoEntryKey

        public int getNoEntryKey()
        Returns the value that is used to represent null as a key. The default value is generally zero, but can be changed during construction of the collection.
        Returns:
        the value that represents null

      • getNoEntryValue

        public long getNoEntryValue()
        Returns the value that is used to represent null. The default value is generally zero, but can be changed during construction of the collection.
        Returns:
        the value that represents null

      • setUp

        protected int setUp(int initialCapacity)
        initializes the hashtable to a prime capacity which is at least initialCapacity + 1.
        Overrides:
        setUp in class  TPrimitiveHash
        Parameters:
        initialCapacity - an int value
        Returns:
        the actual capacity chosen

      • contains

        public boolean contains(int val)
        Searches the set for val
        Parameters:
        val - an int value
        Returns:
        a boolean value

      • forEach

        public boolean forEach(TIntProcedure procedure)
        Executes procedure for each key in the map.
        Parameters:
        procedure - a TIntProcedure value
        Returns:
        false if the loop over the set terminated because the procedure returned false for some value.

      • removeAt

        protected void removeAt(int index)
        Releases the element currently stored at index.
        Overrides:
        removeAt in class  TPrimitiveHash
        Parameters:
        index - an int value

      • index

        protected int index(int key)
        Locates the index of val.
        Parameters:
        key - an int value
        Returns:
        the index of val or -1 if it isn't in the set.

      • insertKey

        protected int insertKey(int val)
        Locates the index at which val can be inserted. if there is already a value equal()ing val in the set, returns that value as a negative integer.
        Parameters:
        key - an int value
        Returns:
        an int value

      • XinsertKey

        protected int XinsertKey(int key)
