Method Detail

objectNode

public static com.fasterxml.jackson.databind.node.ObjectNode objectNode()

arrayNode

public static com.fasterxml.jackson.databind.node.ArrayNode arrayNode()

stringProperty

public static String stringProperty(com.fasterxml.jackson.databind.JsonNode node,
                                    String propertyName)

Extract a string property from the given json tree. Returns null if no property exists or is not a text node.

Parameters:

node - JsonNode

propertyName - Property to extract

Returns:

String holding the value found for the property

stringProperty

public static void stringProperty(com.fasterxml.jackson.databind.node.ObjectNode node,
                                  String propertyName,
                                  String propertyValue)

Sets the value of a property for a given json node. If the value is null, then the property is not written.

Parameters:

node - ObjectNode

propertyName - Property to be set

propertyValue - Value to be set

enumProperty

public static <E extends Enum<E>> void enumProperty(com.fasterxml.jackson.databind.node.ObjectNode node,
                                                    String propertyName,
                                                    E propertyValue)

Sets the value of a property for a given json node. If the value is null, then the property is not written.

Type Parameters:

E - Type of the property value

Parameters:

node - ObjectNode

propertyName - Property to be set

propertyValue - Value to be set

booleanProperty

public static Boolean booleanProperty(com.fasterxml.jackson.databind.JsonNode node,
                                      String propertyName)

Extract a boolean property from the given json tree. Returns null if no property exists or is not a boolean node.

Parameters:

node - JsonNode

propertyName - Property to extract

Returns:

Boolean containing the value extracted

booleanProperty

public static void booleanProperty(com.fasterxml.jackson.databind.node.ObjectNode node,
                                   String propertyName,
                                   Boolean propertyValue)

Sets the value of a property for a given json node. If the value is null, then the property is not written.

Parameters:

node - ObjectNode

propertyName - Property to be set

propertyValue - Boolean value to be set

intProperty

public static Integer intProperty(com.fasterxml.jackson.databind.JsonNode node,
                                  String propertyName)

Extract a integer property from the given json tree. Returns null if no property exists or is not a boolean node.

Parameters:

node - JsonNode

propertyName - Property to extract

Returns:

Integer containing the extracted value

intProperty

public static void intProperty(com.fasterxml.jackson.databind.node.ObjectNode node,
                               String propertyName,
                               Integer propertyValue)
