io.apicurio.datamodels.util.NodeUtil

public class NodeUtil
extends Object

A utility class containing methods used to interact with data model nodes. Anything that needs to be handled differently (with respect to data model nodes) in Java vs. TS/JS should be done here. There is a NodeUtil.ts file that contains the TS/JS specific implementation of this class.

Method Detail

getProperty

public static Object getProperty(Object node,
                                 String propertyName)

setProperty

public static void setProperty(Object node,
                               String propertyName,
                               Object newValue)

getNodeProperty

public static Object getNodeProperty(Node node,
                                     String propertyName)

Returns the value for a given node property.

Parameters:

node -

propertyName -

isNode

public static boolean isNode(Object object)

Return true if the given object is a Node.

Parameters:

object -

isDefinition

public static boolean isDefinition(Node node)

Return true if the given node is a definition. A node is a definition in both AsyncAPI and OpenAPI if it is defined in a way that makes it reusable elsewhere in the document.

Parameters:

node -

isUnion

public static boolean isUnion(Object object)

Return true if the given object is a Union type.

Parameters:

object -

isList

public static boolean isList(Object object)

Returns true if the given object is a list.

Parameters:

object -

isMap

public static boolean isMap(Object object)

Returns true if the given object is a list.

Parameters:

object -

getMapItem

public static Object getMapItem(Map map,
                                String key)

Gets an item out of a map. Needed due to transpilation wierdness.

Parameters:

map -

key -

toInteger

public static int toInteger(String value)

Converts a string value to an integer (it's expected to be formatted as an int).

Parameters:

value -

isNullOrUndefined

public static boolean isNullOrUndefined(Object value)

Returns true if the given value is null or undefined.

Parameters:

value -

isDefined

public static boolean isDefined(Object value)

Returns true if the given value is defined (ie if the value is NOT null or undefined).

Parameters:

value -

asList

public static List<String> asList(String... items)

Creates a list from a bunch of argument items.

Parameters:

items -

asArray

public static String[] asArray(List<String> list)

Turns a list into an array.

Parameters:

list -

copyList

public static List<String> copyList(List<String> list)

Makes a copy of a list.

Parameters:

list -

equals

public static boolean equals(Object value1,
                             Object value2)

Tests two objects for equality.

Parameters:

value1 -

value2 -

getMapKeys

public static Collection<String> getMapKeys(Map<String,?> map)

Gets the keys from the given map.

Parameters:

map -

getMapValues

public static <T> Collection<T> getMapValues(Map<String,T> map)

Gets the values from the given map.

Parameters:

map -
