Method Detail

hierarchyFilter

public static <T extends IHierarchialReference<I>,I> List hierarchyFilter(List<T> list,
                                                                          boolean loadLeaves)

From a flat list creates a List of List & IHierarchialReferences (as nodes). The list need not be ordered but the parents should appear early in the List. Algo complexity: 2 parses of list.

Example:

• ROOT
• Node 1 - Object in the Child list of the parent
• Node 2 as Sub List 1 - Object as List in the Child List of the Parent. Since its a list it has no meta data and hence needs meta data
• Sub List 1 Node 0 - Represents the meta data for the parent
• Sub List 1 Node 1
• Sub List 1 Node 2
• Node 3

Parameters:

list -

Returns:

List
