Following are code examples for creating treemap and sunburst components.
When you create a treemap or sunburst using UI-first development, you can use Java classes and managed beans to define the tree node and tree model, populate the tree with data and add additional methods as needed to configure the treemap or sunburst.
Example F-2 shows a code sample defining the tree node in the census data example. Note that the required settings for label, size, and color are passed in as parameters to the tree node.
Example F-2 Code Sample to Create a Treemap or Sunburst Tree Node
import java.awt.Color;
import java.util.ArrayList;
import java.util.List;
public class TreeNode {
private final String m_text;
private final Number m_size;
private final Color m_color;
private final List<TreeNode> m_children = new ArrayList<TreeNode>();
public TreeNode(String text, Number size, Color color) {
m_text = text;
m_size = size;
m_color = color;
}
public String getText() {
return m_text;
}
public Number getSize() {
return m_size;
}
public Color getColor() {
return m_color;
}
public void addChild(TreeNode child) {
m_children.add(child);
}
public void addChildren(List<TreeNode> children) {
m_children.addAll(children);
}
public List<TreeNode> getChildren() {
return m_children;
}
@Override
public String toString() {
return m_text + ": " + m_color + " " + Math.round(m_size.doubleValue());
}
}
To supply data to the treemap or sunburst in UI-first development, add a class or managed bean to your application that extends the tree node in Example F-2 and populates it with data. The class to set up the tree model must be an implementation of the org.apache.myfaces.trinidad.model.TreeModel class. Once the tree model is defined, create a method that implements the org.apache.myfaces.trinidad.model.ChildPropertyTreeModel to complete the tree model.
Example F-3 shows a sample class that sets up the root and child node structure, populates the child levels with data and defines the color and node sizes in the census data example.

Finally, to complete the tree model in UI-first development, add a managed bean to your application that references the class or bean that contains the data and, optionally, add any other methods to customize the treemap or sunburst.
Example F-4 shows a code sample that will instantiate the census treemap and populate it with census data. The example also includes a sample method (convertToString) that will convert the treemap node's row data to a string for label display.
Example F-4 Managed Bean Example to Set Census Data Treemap

}

StringBuilder s = new StringBuilder();
if (rowKeySet != null) {
for (Object rowKey : rowKeySet) {

s.append(rowData.getText()).append(", ");
}
// Remove the trailing comma
if (s.length() > 0)
s.setLength(s.length() - 2);
}
return s.toString();
}
public void setTreemap(UITreemap treemap) {
this.treemap = treemap;
}
public UITreemap getTreemap() {
return treemap;
}
}
The code to set up the sunburst census sample is nearly identical since both components use the same tree model. See Section F.2.2, "Code Sample for Sunburst Managed Bean" for an example.
The following code sample instantiates the census sunburst and populates it with census data. The example also includes a sample method (convertToString) that will convert the sunburst node's row data to a string for label display.
