JStructure (Castor XML - Code generator 1.4.1 API)

java.lang.Object
- org.exolab.javasource.JType
- - org.exolab.javasource.JStructure

All Implemented Interfaces:

JAnnotatedElement

Direct Known Subclasses:

AbstractJClass, JAnnotationType, JInterface
```
public abstract class JStructure
extends JType
implements JAnnotatedElement
```
This class represents the basic Java "structure" for a Java source file. This is the base class for JClass and JInterface.
This is a useful utility when creating in memory source code. The code in this package was modelled after the Java Reflection API as much as possible to reduce the learning curve.
