public static final String DEFAULT_CHILDREN_COMBINATION_MODE
This default mode for combining children DOMs during merge means that where element names
match, the process will try to merge the element data, rather than putting the dominant
and recessive elements (which share the same element name) as siblings in the resulting
DOM.
DEFAULT_SELF_COMBINATION_MODE
public static final String DEFAULT_SELF_COMBINATION_MODE
This default mode for combining a DOM node during merge means that where element names
match, the process will try to merge the element attributes and values, rather than
overriding the recessive element completely with the dominant one. This means that
wherever the dominant element doesn't provide the value or a particular attribute, that
value or attribute will be set from the recessive DOM node.

mergeIntoXpp3Dom
private static void mergeIntoXpp3Dom(Xpp3Dom dominant,
Xpp3Dom 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).
A. 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.
B. 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
A. if the dominant root node's value is empty, set it to the recessive root node's value
B. For each attribute in the recessive root node which is not set in the dominant root node, set it.
C. Determine whether children from the recessive DOM will be merged or appended to the dominant
DOM as siblings (flag=mergeChildren).
i. if childMergeOverride is set (non-null), use that value (true/false)
ii. retrieve the 'combine.children' attribute on the dominant node, and try to match against
'append'...if it matches 'append', then set mergeChildren == false...the recessive children
will be appended as siblings of the dominant children.
iii. 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.
D. Iterate through the recessive children, and:
i. if mergeChildren == true and there is a corresponding dominant child (matched by element name),
merge the two.
ii. otherwise, add the recessive child as a new child on the dominant root node.
mergeXpp3Dom
public static Xpp3Dom mergeXpp3Dom(Xpp3Dom dominant,
Xpp3Dom 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 mergedrecessive
- The recessive DOM, which will be merged into the dominant DOM
