org.jboss.hal.dmr.ModelNodeHelper

public class ModelNodeHelper
extends Object

Static helper methods for dealing with ModelNodes and NamedNodes. Some methods accept a path parameter separated by "/" to get a deeply nested data.

Method Summary

Modifier and Type	Method	Description
static <E extends Enum<E>> String	asAttributeValue(E enumValue)	The reverse operation to asEnumValue(ModelNode, String, Function, Enum).
static <E extends Enum<E>> E	asEnumValue(ModelNode modelNode, String attribute, Function<String,E> valueOf, E defaultValue)	Looks for the specified attribute and tries to convert it to an enum constant using LOWER_HYPHEN.to(UPPER_UNDERSCORE, modelNode.get(attribute).asString()).
static <E extends Enum<E>> E	asEnumValue(ModelNode modelNodeValue, Function<String,E> valueOf, E defaultValue)
static List<NamedNode>	asNamedNodes(List<Property> properties)	Turns a list of properties into a list of named model nodes which contains a ModelDescriptionConstants.NAME key with the properties name.
static String	decodeValue(String value)
static String	encodeValue(String value)
static boolean	failSafeBoolean(ModelNode modelNode, String path)	Tries to get a deeply nested boolean value from the specified model node.
static Date	failSafeDate(ModelNode modelNode, String path)
static ModelNode	failSafeGet(ModelNode modelNode, String path)	Tries to get a deeply nested model node from the specified model node.
static List<ModelNode>	failSafeList(ModelNode modelNode, String path)
static List<Property>	failSafePropertyList(ModelNode modelNode, String path)
static ModelNode	flatToNested(ModelNode modelNode)	Turns all properties which contain one or more '.' into nested model nodes.
static <T> T	getOrDefault(ModelNode modelNode, String attribute, Supplier<T> supplier, T defaultValue)
static void	move(ModelNode modelNode, String source, String destination)	Moves an attribute to another destination.
static ModelNode	properties(String... properties)	Turns a list of properties (keys and values) into a model node.
static <T extends ModelNode> void	storeIndex(List<T> modelNodes)

Method Detail

encodeValue

public static String encodeValue(String value)

decodeValue

public static String decodeValue(String value)

failSafeGet

public static ModelNode failSafeGet(ModelNode modelNode,
                                    String path)

Tries to get a deeply nested model node from the specified model node. Nested paths must be separated with "/".

Parameters:

modelNode - The model node to read from

path - A path separated with "/"

Returns:

The nested node or an empty / undefined model node

failSafeBoolean

public static boolean failSafeBoolean(ModelNode modelNode,
                                      String path)

Tries to get a deeply nested boolean value from the specified model node. Nested paths must be separated with "/".

Parameters:

modelNode - The model node to read from

path - A path separated with "/"

Returns:

the boolean value or false.

failSafeDate

public static Date failSafeDate(ModelNode modelNode,
                                String path)

failSafeList

public static List<ModelNode> failSafeList(ModelNode modelNode,
                                           String path)

failSafePropertyList

public static List<Property> failSafePropertyList(ModelNode modelNode,
                                                  String path)

getOrDefault

public static <T> T getOrDefault(ModelNode modelNode,
                                 String attribute,
                                 Supplier<T> supplier,
                                 T defaultValue)

storeIndex

public static <T extends ModelNode> void storeIndex(List<T> modelNodes)

asNamedNodes

public static List<NamedNode> asNamedNodes(List<Property> properties)

Turns a list of properties into a list of named model nodes which contains a ModelDescriptionConstants.NAME key with the properties name.

asEnumValue

public static <E extends Enum<E>> E asEnumValue(ModelNode modelNode,
                                                String attribute,
                                                Function<String,E> valueOf,
                                                E defaultValue)

Looks for the specified attribute and tries to convert it to an enum constant using LOWER_HYPHEN.to(UPPER_UNDERSCORE, modelNode.get(attribute).asString()).

asEnumValue

public static <E extends Enum<E>> E asEnumValue(ModelNode modelNodeValue,
                                                Function<String,E> valueOf,

asAttributeValue

public static <E extends Enum<E>> String asAttributeValue(E enumValue)
