    • merge

      public static XmlNode merge(XmlNode dominant, XmlNode recessive, Boolean childMergeOverride)
      Merges one DOM into another, given a specific algorithm and possible override points for that algorithm.

      The algorithm is as follows:

      1. if the recessive DOM is null, there is nothing to do... return.
      2. Determine whether the dominant node will suppress the recessive one (flag=mergeSelf).
        1. retrieve the 'combine.self' attribute on the dominant node, and try to match against 'override'... if it matches 'override', then set mergeSelf == false...the dominant node suppresses the recessive one completely.
        2. otherwise, use the default value for mergeSelf, which is true...this is the same as specifying 'combine.self' == 'merge' as an attribute of the dominant root node.
      3. If mergeSelf == true
        1. Determine whether children from the recessive DOM will be merged or appended to the dominant DOM as siblings (flag=mergeChildren).
          1. if childMergeOverride is set (non-null), use that value (true/false)
          2. retrieve the 'combine.children' attribute on the dominant node, and try to match against 'append'...
          3. if it matches 'append', then set mergeChildren == false...the recessive children will be appended as siblings of the dominant children.
          4. otherwise, use the default value for mergeChildren, which is true...this is the same as specifying 'combine.children' == 'merge' as an attribute on the dominant root node.
        2. Iterate through the recessive children, and:
          1. if mergeChildren == true and there is a corresponding dominant child (matched by element name), merge the two.
          2. otherwise, add the recessive child as a new child on the dominant root node.
    • merge

      public static XmlNode merge(XmlNode dominant, XmlNode recessive)
      Merge two DOMs, with one having dominance in the case of collision. Merge mechanisms (vs. override for nodes, or vs. append for children) is determined by attributes of the dominant root node.
      dominant - The dominant DOM into which the recessive value/attributes/children will be merged
      recessive - The recessive DOM, which will be merged into the dominant DOM
      merged DOM
