Method Detail

removeChildAt

public void removeChildAt(int index)

removeLastChild

public void removeLastChild()

swapLastChildWith

public void swapLastChildWith(int childIndex)

locateChild

public int locateChild(Unmarshaller child)
                throws java.lang.Exception

Returns the index of the child in the specified children collection. Iterated through the collection until the child is found, and returns the index. Of course, to do anything with the child the caller will have to once again iterate through the collection - wish collections were lists...

The way the child is located is this: we're matching the attribute of the OHXPath node to the attributes of the children. If no attributes are specified in the OHXPath, we try to match the class name. If that slo doesnt happen, an exception is thrown

todo: verify thats indeed the desired behavior

Parameters:

child - the child to be located

Returns:

index of the child in the collection or -1 if not found

Throws:

java.lang.Exception
