      • Union

        public Union​(int K)
        Constructor: Initialize an empty Union data struct with K Sets/Components indexed 0 to K-1. Each Set/Component has exactly 1 Site/Element initially.
        Parameters:
        K - the number of objects (such as Geometries represented by a label).

      • findSetIdentifier

        public int findSetIdentifier​(int item)
        Returns the Set/Component Identifier in id Array for the Set/Component containing the Site/Element "s".
        Parameters:
        item - the integer which represents the Site/Element
        Returns:
        the Set/Component Identifier in id Array for the Set/Component containing the Site/Element "s".

      • countSets

        public int countSets()
        Returns the number of Sets/Components.
        Returns:
        the number of Sets/Components.

      • countElements

        public int countElements()
        Returns the number of Sites/Elements (i.e., size of id Array).
        Returns:
        the number of Sites/Elements.

      • unionSets

        public void unionSets​(int s,
                      int r)
        This method merges the Set/Component containing Site/Element "s" with the Set/Component containing the Site/Element "r".
        Parameters:
        s - the integer value for first Site/Element
        r - the integer value for second Site/Element

      • areSitesConnected

        public boolean areSitesConnected​(int s,
                                 int r)
        This method determines whether the Set/Component containing Site/Element "s" is the same as the Set/Component containing Site/Element "r". In other words, it tells whether both Sites/Elements are in the same Set/Component.
        Parameters:
        s - the integer value for first Site/Element
        r - the integer value for second Site/Element

      • getAllSetIdentifiersforParents

        public java.util.ArrayList getAllSetIdentifiersforParents()
        This method returns the Set/Component Identifiers for Parent Sites/Elements. As an application: For a valid Simple Solid Geometry: there should be exactly 1 element in the returned ArrayList.
        Returns:
        an ArrayList containing the Set/Component Identifiers for Parent Sites/Elements.
