public interface NavigableObject

This class contains helper methods for navigating deeply nested Objects. Keep in mind that it may be expensive depending on the underlying implementation. each level needs an extra lookup and the lookup may be as expensive as O(log(n)) to O(n) depending on the underlying impl

Method Summary

Modifier and Type	Method and Description
default void	_forEachEntry(BiConsumer fun) Iterate through each entry in this object
default void	_forEachEntry(List<String> path, BiConsumer fun) Iterate through the entries of a navigable Object at a certain path
default void	_forEachEntry(String path, BiConsumer fun) Iterate through the entries of a navigable Object at a certain path
default Object	_get(List<String> path, Object def) Get a child object value using json path
default Object	_get(String path, Object def) Get a child object value using json path.
default String	_getStr(List<String> path, String def)
default String	_getStr(String path, String def) get the value as a String.

Method Detail

_get

default Object _get(String path,
                    Object def)

Get a child object value using json path. This usually ends up in String split operations use a list of strings where performance is important

Parameters:

path - the full path to that object such as a/b/c[4]/d etc

def - the default

Returns:

the found value or default

_getStr

default String _getStr(String path,
                       String def)

get the value as a String. useful in tests

Parameters:

path - the full path

def - default value

_forEachEntry

default void _forEachEntry(String path,
                           BiConsumer fun)

Iterate through the entries of a navigable Object at a certain path

Parameters:

path - the json path

_forEachEntry

default void _forEachEntry(List<String> path,
                           BiConsumer fun)

Iterate through the entries of a navigable Object at a certain path

Parameters:

path - the json path

_forEachEntry

default void _forEachEntry(BiConsumer fun)

Iterate through each entry in this object

_get

default Object _get(List<String> path,
                    Object def)

Get a child object value using json path

Parameters:

path - the full path to that object such as ["a","b","c[4]","d"] etc

def - the default

Returns:

the found value or default

_getStr

default String _getStr(List<String> path,
                       String def)
