List Methods - Find Specific Objects, Add Before

Monkey Forums/Monkey Code/List Methods - Find Specific Objects, Add Before

JD0(Posted 2011) [#1]
A couple of list methods that I have used.. since Monkey seemed to be missing these I made my own List module, and added these two into the List class.
	Method AddBefore:Node<T>(value:T, valueAfter:T)
		Local nodeOfValueAfter:Node<T> = Find(valueAfter)
		
		If nodeOfValueAfter = Null
			Return AddLast(value)
		End
		
		
		Return New Node<T>(nodeOfValueAfter, nodeOfValueAfter._pred, value)
	End

	Method Find:Node<T>(dataToFind:T)
		Local node:=_head._succ
		While node<>_head
			node=node._succ
			If Equals( node._pred._data,dataToFind ) Return node._pred
		Wend	
		
		Return Null
	End
