public Entry getParentEntry()

Return the parent of this Entry

Returns:

the parent of this Entry, or null if this is the root Entry

getChildEntry

public Entry getChildEntry(String pName)

Parameters:

pName - the name of the child Entry

Returns:

the child Entry or null if thee is no such child

Throws:
