Method Detail

map

public PathMap.Element<T> map(Path path,
                              boolean exact)

Map a path to a child. If exact is false, returns the last available item along the path that is stored in the map.

Parameters:

path - path to map

exact - flag indicating whether an exact match is required

Returns:

child, maybe null if exact is true

put

public PathMap.Element<T> put(Path path,
                              T obj)

Create an element given by its path. The path map will create any necessary intermediate elements.

Parameters:

path - path to child

obj - object to store at destination

put

public void put(Path path,
                PathMap.Element<T> element)

Put an element given by its path. The path map will create any necessary intermediate elements.

Parameters:

path - path to child

element - element to store at destination

put

public PathMap.Element<T> put(Path path)

Create an empty child given by its path.

Parameters:

path - path to child

traverse

public void traverse(PathMap.ElementVisitor<T> visitor,
                     boolean includeEmpty)

Traverse the path map and call back requester. This method visits the root first, then its children.

Parameters:

includeEmpty - if true invoke call back on every child regardless, whether the associated object is empty or not; otherwise call back on non-empty children only
