getChild

                          boolean returnEmptyChildIfNotFound)

removeChild

public boolean removeChild(java.lang.String name,
                           java.util.List<ParamNode.RemovedNode> removedNodesList)

Removes a child from this node, but stores what is removed to list. The we can later call which will add it back again. This is a "hack" related to #1195 which makes it possible to reuse the RootParamsNode-structure if you want to perform the bind-operation multiple times.

参数：

name - the name of the child-node in this paramNode which should be removed.

removedNodesList - a list where info about what is removed where is stored.

返回：

true if anything was removed.
