Class MonotonicIntSet

java.lang.Object
net.sf.saxon.z.IntSet
net.sf.saxon.z.MonotonicIntSet
public class MonotonicIntSet extends IntSet
Set of int values. This implementation requires that new entries are added in monotonically increasing order; any attempt to add a value out of sequence, or to remove a value, results is an UnsupportedOperationException

      public MonotonicIntSet()
      Create an empty set

  • 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

    • 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

    • 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)
      Description copied from class: IntSet
      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

    • add

      public boolean add(int value)
      Add an integer to the set
      Specified by:
      add in class IntSet
      Parameters:
      value - the integer to be added (which must be greater than or equal to the largest integer currently in the set)
      Returns:
      true if the integer was added, false if it was already present
      Throws:
      UnsupportedOperationException - if the set already contains an integer larger than the supplied value

    • iterator

      public IntIterator iterator()
      Get an iterator over the values
      Specified by:
      iterator in class IntSet
      Returns:
      an iterator over the values, which will be delivered in sorted order

    • union

      public IntSet union(IntSet other)
      Form a new set that is the union of this set with another set.
      Overrides:

      Parameters:
      other - the other set
      Returns:
      the union of the two sets

    • make

      public static MonotonicIntSet make(int[] in, int size)
      Factory method to construct a set from an array of integers
      Parameters:

    • hashCode

      public int hashCode()
      Construct a hash key that supports the equals() test
