static <M> Map<String,M>	convertNodeMapToHierarchicalKeyMap(NodeMap<String,M> nodeMap, String delimiter) Converts a NodeMap into a normal Map with hierarchical keys.
static <M> Map<String,M>	convertNodeMapWithLastLevelAsMapToHierarchicalKeyMap(NodeMap<String,Map<String,M>> nodeMap, String delimiter) Converts a NodeMap into a normal Map with hierarchical keys.
static <K,V,M> NodeMap<K,Map<K,M>>	newNodeMap(Map<K,V> map, NodeMapFactory.ModelAndChildExtractor<K,V,M> modelAndChildExtractor)
static NodeMap<String,Map<String,Object>>	newNodeMap(Map<String,Object> nestedMap) Returns a new NodeMap for a given Map which contains nested further Map instances
static NodeMap<String,Map<String,Object>>	newNodeMap(Object object) Returns a new NodeMap for a given Object which is based on the Java bean properties
static <V> NodeMap<String,V>	newNodeMapFromHierarchicalKeyMap(Map<String,V> map, String delimiterRegEx) Returns a new NodeMap based on a normal Map containing hierarchical structured keys.
static <V> NodeMap<String,Map<String,V>>	newNodeMapFromHierarchicalKeyMapWithLastLevelAsMap(Map<String,V> map, String delimiterRegEx) Similar to newNodeMapFromHierarchicalKeyMap(Map, String) but having the last hierarchy level put into a Map which acts as model

Method Detail

newNodeMap

public static <K,V,M> NodeMap<K,Map<K,M>> newNodeMap(Map<K,V> map,
                                                     NodeMapFactory.ModelAndChildExtractor<K,V,M> modelAndChildExtractor)

Parameters:

map -

modelAndChildExtractor -

Returns:

newNodeMap

public static NodeMap<String,Map<String,Object>> newNodeMap(Object object)

Returns a new NodeMap for a given Object which is based on the Java bean properties

Parameters:

object -

Returns:

newNodeMap

public static NodeMap<String,Map<String,Object>> newNodeMap(Map<String,Object> nestedMap)

Returns a new NodeMap for a given Map which contains nested further Map instances

Parameters:

nestedMap -

Returns:

newNodeMapFromHierarchicalKeyMap

public static <V> NodeMap<String,V> newNodeMapFromHierarchicalKeyMap(Map<String,V> map,
                                                                     String delimiterRegEx)

Returns a new NodeMap based on a normal Map containing hierarchical structured keys. A hierarchical key could be e.g. node1.subnode1.subsubnode1 where '.' is the delimiter. Note: the point has to be quoted actually using Pattern.quote(String).

Parameters:

map - Map

delimiterRegEx -

Returns:

newNodeMapFromHierarchicalKeyMapWithLastLevelAsMap

public static <V> NodeMap<String,Map<String,V>> newNodeMapFromHierarchicalKeyMapWithLastLevelAsMap(Map<String,V> map,
                                                                                                   String delimiterRegEx)

Similar to newNodeMapFromHierarchicalKeyMap(Map, String) but having the last hierarchy level put into a Map which acts as model

Parameters:

map -

delimiterRegEx -

Returns:

convertNodeMapToHierarchicalKeyMap

public static <M> Map<String,M> convertNodeMapToHierarchicalKeyMap(NodeMap<String,M> nodeMap,

Converts a NodeMap into a normal Map with hierarchical keys.
Example:

 parent +
        |
        +-subnode1
        +-subnode2
 

results in
parent.subnode1=xyz
parent.subnode2=xyz

Parameters:

nodeMap -

delimiter -

Returns:

Example:

 parent +
        |
        Map
          +-subnode1
          +-subnode2
 

results in
