Class JsonNodeFactory

java.lang.Object
  com.fasterxml.jackson.databind.node.JsonNodeFactory

public class JsonNodeFactory
extends Object

Base class that specifies methods for getting access to Node instances (newly constructed, or shared, depending on type), as well as basic implementation of the methods. Designed to be sub-classed if extended functionality (additions to behavior of node types, mostly) is needed.

Field Summary

static JsonNodeFactory

instance Default singleton instance that construct "standard" node instances: given that this class is stateless, a globally shared singleton can be used.

Constructor Summary

protected

JsonNodeFactory()

Method Summary

ArrayNode	arrayNode() Factory method for constructing an empty JSON Array node
BinaryNode	binaryNode(byte[] data) Factory method for constructing a node that represents given binary data, and will get serialized as equivalent base64-encoded String value
BinaryNode	binaryNode(byte[] data, int offset, int length) Factory method for constructing a node that represents given binary data, and will get serialized as equivalent base64-encoded String value
BooleanNode	booleanNode(boolean v) Factory method for getting an instance of JSON boolean value (either literal 'true' or 'false')
NullNode	nullNode() Factory method for getting an instance of JSON null node (which represents literal null value)
NumericNode	numberNode(BigDecimal v) Factory method for getting an instance of JSON numeric value that expresses given unlimited precision floating point value
NumericNode	numberNode(BigInteger v) Factory method for getting an instance of JSON numeric value that expresses given unlimited range integer value
NumericNode	numberNode(byte v) Factory method for getting an instance of JSON numeric value that expresses given 8-bit value
ValueNode	numberNode(Byte value) Alternate factory method that will handle wrapper value, which may be null.
NumericNode	numberNode(double v) Factory method for getting an instance of JSON numeric value that expresses given 64-bit floating point value
ValueNode	numberNode(Double value) Alternate factory method that will handle wrapper value, which may be null.
NumericNode	numberNode(float v) Factory method for getting an instance of JSON numeric value that expresses given 32-bit floating point value
ValueNode	numberNode(Float value) Alternate factory method that will handle wrapper value, which may be null.
NumericNode	numberNode(int v) Factory method for getting an instance of JSON numeric value that expresses given 32-bit integer value
ValueNode	numberNode(Integer value) Alternate factory method that will handle wrapper value, which may be null.
NumericNode	numberNode(long v) Factory method for getting an instance of JSON numeric value that expresses given 64-bit integer value
ValueNode	numberNode(Long value) Alternate factory method that will handle wrapper value, which may be null.
NumericNode	numberNode(short v) Factory method for getting an instance of JSON numeric value that expresses given 16-bit integer value
ValueNode	numberNode(Short value) Alternate factory method that will handle wrapper value, which may be null.
ObjectNode	objectNode() Factory method for constructing an empty JSON Object ("struct") node
POJONode	POJONode(Object pojo) Factory method for constructing a wrapper for POJO ("Plain Old Java Object") objects; these will get serialized using data binding, usually as JSON Objects, but in some cases as JSON Strings or other node types.
TextNode	textNode(String text) Factory method for constructing a node that represents JSON String value

Field Detail

instance

public static final JsonNodeFactory instance

Default singleton instance that construct "standard" node instances: given that this class is stateless, a globally shared singleton can be used.

Constructor Detail

JsonNodeFactory

protected JsonNodeFactory()

Method Detail

booleanNode

public BooleanNode booleanNode(boolean v)

Factory method for getting an instance of JSON boolean value (either literal 'true' or 'false')

nullNode

public NullNode nullNode()

Factory method for getting an instance of JSON null node (which represents literal null value)

numberNode

public NumericNode numberNode(byte v)

numberNode

public NumericNode numberNode(int v)

Factory method for getting an instance of JSON numeric value that expresses given 32-bit integer value

numberNode

public ValueNode numberNode(Integer value)

Alternate factory method that will handle wrapper value, which may be null. Due to possibility of null, returning type is not guaranteed to be NumericNode, but just ValueNode.

public NumericNode numberNode(long v)

Factory method for getting an instance of JSON numeric value that expresses given 64-bit integer value

numberNode

public ValueNode numberNode(Long value)

Alternate factory method that will handle wrapper value, which may be null. Due to possibility of null, returning type is not guaranteed to be NumericNode, but just ValueNode.

numberNode

public NumericNode numberNode(BigInteger v)
