TreePath

public TreePath()

Create an empty tree path.

TreePath

public TreePath(List<String> initialPathEntries)

Create a tree path from a list.

Parameters:

initialPathEntries - Entries in the path.

TreePath

public TreePath(String initialPathEntry,
                String... args)

Create a tre path.

Method Detail

isEmptyPath

public static boolean isEmptyPath(TreePath path)

Determines if a path is empty.

Parameters:

path - Path to test.

Returns:

true if path contains no entries, path is null, or if the first entry of path is null or an empty string.

lastButOne

public TreePath lastButOne()

Retrieves the a sub-section of this path from the first element to the second to last element.

Returns:

a new TreePath that contains the entries in this path, excluding the final entry.

subPath

public TreePath subPath(int start,
                        int end)

Retrieves a subsection of the path.

Parameters:

start - first index (inclusive) of the sub-path

end - last index (exclusive) of the sub-path
