KeyTree

public KeyTree(ConfigurationOptions options)

Method Details

findParent

public KeyTree.Node findParent(int indent)

Get the last node that can be a parent of a child with the indent provided.

Parameters:

indent - the indent to look for

Returns:

the last most inner child that has less indent than the indent provided, or parent otherwise

getRoot

public KeyTree.Node getRoot()

Get the root node.

Returns:

the root node of this key tree

get

public KeyTree.Node get(String path)

Get a child from its path. May contain repetitions with list elements when using names (values can be repeated on a list).

Parameters:

path - the path of names to look for separated by options() ConfigurationOptions.pathSeparator()

Returns:

the child that has the provided path or null if not found

getPriority

public KeyTree.Node getPriority(String path)

Get a child from its path. Repetitions on list values are only allowed to keys inserted with priority using add(String).

Parameters:

path - the path of names to look for separated by options() ConfigurationOptions.pathSeparator()

Returns:

the child that has the provided path or null if not found

getOrAdd

public KeyTree.Node getOrAdd(String path)

Get a child from its path. It is created if it does not exist.

Parameters:

path - the path of names to look for separated by options() ConfigurationOptions.pathSeparator()

Returns:

the child that has the provided path

add

public KeyTree.Node add(String path)

Get a child from its path. It is created with priority if it does not exist.

Parameters:

path - the path of names to look for separated by options() ConfigurationOptions.pathSeparator()

Returns:

the child that has the provided path
