JsonNodeFactory (Jackson JSON Processor)

java.lang.Object
- org.codehaus.jackson.node.JsonNodeFactory

```
public class JsonNodeFactory
extends java.lang.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.

Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`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(byte v)`	Factory method for getting an instance of JSON numeric value that expresses given 8-bit value
`NumericNode`	`numberNode(double v)`	Factory method for getting an instance of JSON numeric value that expresses given 64-bit floating point value
`NumericNode`	`numberNode(float v)`	Factory method for getting an instance of JSON numeric value that expresses given 32-bit floating point value

`ValueNode`	`numberNode(java.lang.Byte value)`	Alternate factory method that will handle wrapper value, which may be null.
`ValueNode`	`numberNode(java.lang.Double value)`	Alternate factory method that will handle wrapper value, which may be null.
`ValueNode`	`numberNode(java.lang.Float value)`	Alternate factory method that will handle wrapper value, which may be null.
`ValueNode`	`numberNode(java.lang.Integer value)`	Alternate factory method that will handle wrapper value, which may be null.

`NumericNode`	`numberNode(java.math.BigInteger v)`	Factory method for getting an instance of JSON numeric value that expresses given unlimited range integer value
`ObjectNode`	`objectNode()`	Factory method for constructing an empty JSON Object ("struct") node
`POJONode`	`POJONode(java.lang.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.
