merge

protected java.lang.Object merge(java.lang.Object child,
                     java.lang.Object parent)

Merge two objects. If the child is null, the parent will be returned. Else the child will be returned.

Parameters:

child - the child object to merge

parent - the parent object to merge

Returns:

the merged string

merge

protected java.lang.String merge(java.lang.String child,
                     java.lang.String parent)

Merge two strings. If the child is null, the parent will be returned. Else the child will be returned.

Parameters:

child - the child string to merge

parent - the parent string to merge

Returns:

the merged string

merge

protected Model merge(Model child,
          Model parent)

Merge two model elements. If the child is null, the parent will be returned. Else the parent element will be merged into the child element with the result returned

Parameters:

child - the child model element to merge

parent - the parent model element to merge

Returns:

the merged element model

merge

protected java.util.LinkedList merge(java.util.LinkedList child,
                         java.util.LinkedList parent)

Merge two lists. All child element will be in the merged list. All parent elements not in the child list will be added. Mergeable elements in both lists will be merged according to that element merge rules. New items are added to the end of the list

Parameters:

child - the child list to merge

parent - the parent list to merge

Returns:

the merged list

merge

protected java.util.LinkedList merge(java.util.LinkedList child,
                         java.util.LinkedList parent,
                         boolean addAtEnd)

Merge two lists. All child element will be in the merged list. All parent elements not in the child list will be added. Mergeable elements in both lists will be merged according to that element merge rules.

Parameters:

child - the child list to merge

parent - the parent list to merge

addAtEnd - if true new items will be added at the end of the list, otherwise the beginning

Returns:

the merged list
