Class SchemaTreeTraverser

java.lang.Object

com.sun.xml.xsom.impl.util.SchemaTreeTraverser

All Implemented Interfaces:

XSContentTypeVisitor, XSSimpleTypeVisitor, XSTermVisitor, XSVisitor

public class SchemaTreeTraverser
extends java.lang.Object
implements XSVisitor, XSSimpleTypeVisitor

Generates approximated tree model for XML from a schema component. This is not intended to be a fully-fledged round-trippable tree model.

Usage of this class

1. Create a new instance.
2. Call visit(com.sun.xml.xsom.XSSchemaSet) function on your schema set.>/li>
3. Retrieve the model using getModel().

Every node in the resulting tree is a SchemaTreeTraverser.SchemaTreeNode, and the model itself is SchemaTreeTraverser.SchemaTreeModel. You can use SchemaTreeTraverser.SchemaTreeCellRenderer as a cell renderer for your tree.
