    IntSet
    public class IntBlockSet
extends java.lang.Object
implements IntSet

      • IntBlockSet

        public IntBlockSet​(int startPoint,
                   int endPoint)
        Create an IntRangeSet given the start point and end point of the integer range.
        Parameters:
        startPoint - the start point of the integer range
        endPoint - the end point of the integer range
        Throws:
        java.lang.IllegalArgumentException - if the two arrays are different lengths. Other error conditions in the input are not currently detected.

    • Method Detail

      • copy

        public IntSet copy()
        Description copied from interface: IntSet
        Create a copy of this IntSet that leaves the original unchanged.
        Specified by:
        copy in interface IntSet
        Returns:
        an IntSet containing the same integers. The result will not necessarily be the same class as the original. It will either be an immutable object, or a newly constructed object.

      • mutableCopy

        public IntSet mutableCopy()
        Description copied from interface: IntSet
        Create a copy of this IntSet that contains the same set of integers.
        Specified by:
        mutableCopy in interface IntSet
        Returns:
        an IntSet containing the same integers. The result will not necessarily be the same class as the original. It will always be a mutable object

      • isMutable

        public boolean isMutable()
        Description copied from interface: IntSet
        Ask whether the set permits in-situ modifications using add() and remove()
        Specified by:
        isMutable in interface IntSet

      • size

        public int size()
        Description copied from interface: IntSet
        Get the number of integers in the set
        Specified by:
        size in interface IntSet
        Returns:
        the size of the set

      • isEmpty

        public boolean isEmpty()
        Description copied from interface: IntSet
        Determine if the set is empty
        Specified by:
        isEmpty in interface IntSet
        Returns:
        true if the set is empty, false if not

      • contains

        public boolean contains​(int value)
        Description copied from interface: IntSet
        Determine whether a particular integer is present in the set
        Specified by:
        contains in interface IntSet
        Parameters:
        value - the integer under test
        Returns:
        true if value is present in the set, false if not

      • remove

        public boolean remove​(int value)
        Remove an integer from the set
        Specified by:
        remove in interface IntSet
        Parameters:
        value - the integer to be removed
        Returns:
        true if the integer was present in the set, false if it was not present
