        public void join​(Attribute a,
                 Attribute b)
          throws java.lang.Exception
        Adds all values from the second Attribute object to the first one (if they are not already present).
        Parameters:
        a - the attribute that will accept additional values
        b - the attribute whose values will be added to the first one
        Throws:
        java.lang.Exception - if a problem occurs

      • differs

        public boolean differs​(Attribute a,
                       Attribute b)
                throws java.lang.Exception
        Compares two Attribute objects and returns if they are different.
        Parameters:
        a - first Attribute object
        b - second Attribute object
        Returns:
        true if the attributes are different, otherwise false
        Throws:
        java.lang.Exception - if a problem occurs

      • vectorContains

        public boolean vectorContains​(java.lang.Object val,
                              java.util.Vector<java.lang.Object> v,
                              boolean dn)
        Return true if and only if a Vector contains a value, and remove that value from the Vector. Look into the values if they are complex. If dn is true, also compact Strings (by removing some spaces).
        Parameters:
        val - an Object that will be searched
        v - the vector whose contents will be checked
        dn - determines whether strings need to be compact or not
        Returns:
        true if the vector contains the given Object, otherwise false

      • compareEntries

        public java.util.ArrayList<ModificationItem> compareEntries​(Entry a,

        Compares two given Entry objects and returns an ArrayList with the differences (attributes that were in one of the entries and not the other).
        Parameters:
        a - first Entry object
