Class IntToIntArrayMap

  • All Implemented Interfaces:
    IntToIntMap
    public class IntToIntArrayMap
extends java.lang.Object
implements IntToIntMap
    An implementation of IntToIntMap that relies on serial searching, and is therefore optimized for very small map sizes

    • Constructor Detail

      • IntToIntArrayMap

        public IntToIntArrayMap()
        Create an initial empty map with default space allocation

      • IntToIntArrayMap

        public IntToIntArrayMap​(int capacity)
        Create an initial empty map with a specified initial capacity
        Parameters:
        capacity - the initial capacity (the number of entries that can be held before more space is allocated)

    • Method Detail

      • clear

        public void clear()
        Clear the map.
        Specified by:
        clear in interface IntToIntMap

      • find

        public boolean find​(int key)
        Finds a key in the map.
        Specified by:
        find in interface IntToIntMap
        Parameters:
        key - Key
        Returns:
        true if the key is mapped

      • get

        public int get​(int key)
        Gets the value for this key.
        Specified by:
        get in interface IntToIntMap
        Parameters:
        key - Key
        Returns:
        the value, or the default value if not found.

      • getDefaultValue

        public int getDefaultValue()
        Get the default value used to indicate an unused entry
        Specified by:
        getDefaultValue in interface IntToIntMap
        Returns:
        the value to be returned by get(int) if no entry exists for the supplied key

      • keyIterator

        public IntIterator keyIterator()
        Get an iterator over the integer key values held in the hash map.

        The contents of the hash map must not be modified while this iterator remains in use

        Specified by:
        keyIterator in interface IntToIntMap
        Returns:
        an iterator whose next() call returns the key values (in arbitrary order)

      • put

        public void put​(int key,
                int value)
        Adds a key-value pair to the map.
        Specified by:
        put in interface IntToIntMap
        Parameters:
        key - Key
        value - Value

      • remove

        Removes a key from the map.
        Specified by:
        remove in interface IntToIntMap
        Parameters:
        key - Key to remove
        Returns:
        true if the value was removed

      • setDefaultValue

        public void setDefaultValue​(int defaultValue)
        Set the value to be returned to indicate an unused entry
        Specified by:
        setDefaultValue in interface IntToIntMap
        Parameters:
        defaultValue - the value to be returned by get(int) if no entry exists for the supplied key

      • size

        public int size()
        Gets the size of the map.
        Specified by:
        size in interface IntToIntMap
