BarRendererpublic class BarRenderer extends javax.faces.render.Renderer | This class is a JSF Renderer for the "javax.faces.Data"
component type. |
| Methods Summary |
|---|
| public void | encodeChildren(javax.faces.context.FacesContext context, javax.faces.component.UIComponent component)Renders the component by letting its UIColumn children process
one row at a time, starting with the row specified by the "first"
attribute for the number of rows specified by the "rows" attribute,
or until the lasy row is reached. If an explicit ID is set for
the component, the component's client ID value is used as the
"id" attribute value on a "span" element that wraps all output
produced by the children.
if (!component.isRendered()) {
return;
}
String clientId = null;
if (component.getId() != null &&
!component.getId().startsWith(UIViewRoot.UNIQUE_ID_PREFIX)) {
clientId = component.getClientId(context);
}
ResponseWriter out = context.getResponseWriter();
if (clientId != null) {
out.startElement("span", component);
out.writeAttribute("id", clientId, "id");
}
UIData data = (UIData) component;
int first = data.getFirst();
int rows = data.getRows();
for (int i = first, n = 0; rows == 0 || n < rows; i++, n++) {
data.setRowIndex(i);
if (!data.isRowAvailable()) {
break;
}
Iterator j = data.getChildren().iterator();
while (j.hasNext()) {
UIComponent column = (UIComponent) j.next();
if (!(column instanceof UIColumn)) {
continue;
}
encodeRecursive(context, column);
}
}
if (clientId != null) {
out.endElement("span");
}
| | private void | encodeRecursive(javax.faces.context.FacesContext context, javax.faces.component.UIComponent component)Calls the appropriate encoding methods on the component and
calls itself recursively for all component children.
if (!component.isRendered()) {
return;
}
component.encodeBegin(context);
if (component.getRendersChildren()) {
component.encodeChildren(context);
} else {
Iterator i = component.getChildren().iterator();
while (i.hasNext()) {
UIComponent child = (UIComponent) i.next();
encodeRecursive(context, child);
}
}
component.encodeEnd(context);
