All Implemented Interfaces:

Iterable<JsonNode>, JsonSerializable, JsonSerializableWithType

public final class POJONode
extends ValueNode

Value node that contains a wrapped POJO, to be serialized as a JSON constructed through data mapping (usually done by calling ObjectMapper).

Method Summary

JsonToken	asToken() Method that can be used for efficient type detection when using stream abstraction for traversing nodes.
boolean	equals(Object o) Equality for node objects is defined as full (deep) value equality.
Object	getPojo() Method that can be used to access the POJO this node wraps.
double	getValueAsDouble(double defaultValue) Method that will try to convert value of this node to a Java double.
int	getValueAsInt(int defaultValue) Method that will try to convert value of this node to a Java int.
long	getValueAsLong(long defaultValue) Method that will try to convert value of this node to a Java long.
String	getValueAsText() Method that will return valid String representation of the container value, if the node is a value node (method JsonNode.isValueNode() returns true), otherwise null.
int	hashCode()
boolean	isPojo() Method that can be used to check if the node is a wrapper for a POJO ("Plain Old Java Object" aka "bean".
void	serialize(JsonGenerator jg, SerializerProvider provider) Method called to serialize node instances using given generator.
String	toString() Note: marked as abstract to ensure all implementation classes define it properly.

POJONode

public POJONode(Object v)

Method Detail

asToken

public JsonToken asToken()

Description copied from class: BaseJsonNode

Method that can be used for efficient type detection when using stream abstraction for traversing nodes. Will return the first JsonToken that equivalent stream event would produce (for most nodes there is just one token but for structured/container types multiple)

Specified by:

asToken in class ValueNode

isPojo

public boolean isPojo()

Description copied from class: JsonNode

Method that can be used to check if the node is a wrapper for a POJO ("Plain Old Java Object" aka "bean". Returns true only for instances of POJONode.

Overrides:

isPojo in class JsonNode

Returns:

True if this node wraps a POJO

getValueAsText

public String getValueAsText()

Description copied from class: JsonNode

Method that will return valid String representation of the container value, if the node is a value node (method JsonNode.isValueNode() returns true), otherwise null.

Note: to serialize nodes of any type, you should call JsonNode.toString() instead.

Specified by:

getValueAsText in class JsonNode

getValueAsInt

public int getValueAsInt(int defaultValue)

Description copied from class: JsonNode

Method that will try to convert value of this node to a Java int. Numbers are coerced using default Java rules; booleans convert to 0 (false) and 1 (true), and Strings are parsed using default Java language integer parsing rules.

If representation can not be converted to an int (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.

Overrides:

getValueAsInt in class JsonNode

getValueAsLong

public long getValueAsLong(long defaultValue)

Description copied from class: JsonNode

Method that will try to convert value of this node to a Java long. Numbers are coerced using default Java rules; booleans convert to 0 (false) and 1 (true), and Strings are parsed using default Java language integer parsing rules.

If representation can not be converted to an long (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.

Overrides:

getValueAsLong in class JsonNode

getValueAsDouble

public double getValueAsDouble(double defaultValue)

Description copied from class: JsonNode

Method that will try to convert value of this node to a Java double. Numbers are coerced using default Java rules; booleans convert to 0.0 (false) and 1.0 (true), and Strings are parsed using default Java language integer parsing rules.

If representation can not be converted to an int (including structured types like Objects and Arrays), specified defaultValue will be returned; no exceptions are thrown.

Overrides:

getValueAsDouble in class JsonNode

serialize

public final void serialize(JsonGenerator jg,
                            SerializerProvider provider)
                     throws IOException,
                            JsonProcessingException

Description copied from class: BaseJsonNode

Method called to serialize node instances using given generator.

Specified by:

serialize in interface JsonSerializable

Specified by:

serialize in class BaseJsonNode

Throws:

IOException

JsonProcessingException

getPojo

public Object getPojo()

Method that can be used to access the POJO this node wraps.

equals

public boolean equals(Object o)

Description copied from class: JsonNode

Equality for node objects is defined as full (deep) value equality. This means that it is possible to compare complete JSON trees for equality by comparing equality of root nodes.

Note: marked as abstract to ensure all implementation classes define it properly and not rely on definition from Object.

Specified by:

equals in class JsonNode

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Description copied from class: JsonNode

Note: marked as abstract to ensure all implementation classes define it properly.

Overrides:

toString in class ValueNode
