ValueNode (Data Pipeline JavaDoc)

java.lang.Object
- com.northconcepts.datapipeline.core.Node
- - com.northconcepts.datapipeline.core.ValueNode<T>

All Implemented Interfaces:

Session, Serializable, Cloneable, Comparable<ValueNode<T>>

Direct Known Subclasses:

ArrayValue, Record, SingleValue
```
public abstract class ValueNode<T>
extends Node
implements Comparable<ValueNode<T>>, Cloneable
```
ValueNode is the base class for all persistent values held in fields and arrays. Values can be:
- Single values (boolean, date, string, etc. -- FieldType)
- Records
- Array of single values, records, and arrays
See Also:

SingleValue, Record, ArrayValue, Node, Field, FieldType, Serialized Form
