Method Summary
Navigator add(java.lang.Object o1, java.lang.Object... others)

adds the given arguments to a list at this point (will not descend into maps, and will not flatten lists)
protected static void addFlattened(java.util.Collection target, java.lang.Object item)

protected static void addInternal(java.lang.Object initialFocus, java.lang.Object currentFocus, java.lang.Object o1, java.lang.Object... others)

Navigator addUnflattened(java.lang.Object o1, java.lang.Object... others)

Navigator at(java.lang.Object pathSegment, java.lang.Object... furtherPathSegments)

returns the navigator focussed at the indicated key sequence in the given map
Navigator atArray(java.lang.Object[] furtherPathSegments)

protected Navigator down(java.lang.Object pathSegment)

utility for at(Object, Object...), taking one argument at a time
protected Navigator downList(java.lang.Object pathSegment)

protected Navigator downMap(java.lang.Object pathSegment)

java.lang.Object get()

returns the object at the focus, or null if none
java.lang.Object get(java.lang.Class type)

returns the object at the focus, casted to the given type, null if none
java.lang.Object get(java.lang.Object pathSegment, java.lang.Object... furtherPathSegments)

java.lang.Object getFocusMap()

returns a java.util.Map at the given focus, creating if needed (so never null), throwing if it exists already and is not a map
java.lang.Object getRoot()

returns the object at the root
java.lang.Object getRootMap()

returns the java.util.Map at the root, throwing if root is not a map
Navigator list()

ensures the given focus is a list
Navigator map()

ensures the given focus is a map, creating if needed (and creating inside the list if it is in a list)
protected java.util.List newList()

protected java.util.Map newMap()

Navigator put(java.lang.Object k1, java.lang.Object v1, java.lang.Object... kvOthers)

puts the given key-value pair at the current focus (or multiple such), creating a map if needed, replacing any values stored against keys supplied here; if you wish to merge deep maps, see add(Object, Object...)
Navigator put(java.util.Map map)

as put(Object, Object, Object...) for the kv-pairs in the given map
protected static void putInternal(java.util.Map target, java.lang.Object k1, java.lang.Object v1, java.lang.Object... kvOthers)
