  • Constructor Details

    • 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:
      IllegalArgumentException - if the two arrays are different lengths. Other error conditions in the input are not currently detected.

  • Method Details

    • copy

      public IntSet copy()
      Description copied from class: IntSet
      Create a copy of this IntSet that leaves the original unchanged.
      Specified by:
      copy in class 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 class: IntSet
      Create a copy of this IntSet that contains the same set of integers.
      Specified by:
      mutableCopy in class 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 class: IntSet
      Ask whether the set permits in-situ modifications using add() and remove()
      Overrides:
      isMutable in class IntSet
      Returns:
      true if the set permits in-situ modifications

    • size

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

    • isEmpty

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

    • contains

      public boolean contains(int value)
      Description copied from class: IntSet
      Determine whether a particular integer is present in the set
      Specified by:
      contains in class 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 class IntSet
      Parameters:
      value - the integer to be removed
      Returns:
      true if the integer was present in the set, false if it was not present
      Throws:
      UnsupportedOperationException - (always)

    • clear

      public void clear()
      Description copied from class: IntSet
      Clear the contents of the IntSet (making it an empty set)
      Specified by:
      clear in class IntSet

    • add

      public boolean add(int value)
      Add an integer to the set. Always throws UnsupportedOperationException
      Specified by:
      add in class IntSet
      Parameters:
      value - the integer to be added
      Returns:
      true if the integer was added, false if it was already present
      Throws:
      UnsupportedOperationException - (always)

    • iterator

      public IntIterator iterator()
      Get an iterator over the values
      Specified by:
