Class IntHashSet

java.lang.Object
net.sf.saxon.z.IntSet
net.sf.saxon.z.IntHashSet
public class IntHashSet extends IntSet
Set of int values. This class is modelled on the java.net.Set interface, but it does not implement this interface, because the set members are nint's rather than Objects.

Not thread safe.

  • Constructor Details

    • IntHashSet

      public IntHashSet()
      Initializes a set with a capacity of 8 and a load factor of 0,25.

    • IntHashSet

      public IntHashSet(int capacity)
      Initializes a set with the given capacity and a load factor of 0,25.
      Parameters:
      capacity - the initial capacity.

    • IntHashSet

      public IntHashSet(int capacity, int noDataValue)

      Parameters:
      capacity - the initial capacity.
      noDataValue - the value to use for non-values.

  • 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

    • 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

    • getValues

      public int[] getValues()

    • 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)
      Description copied from class: IntSet
      Add an integer to the set
      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

    • iterator

      public IntIterator iterator()
