Examples of org.apache.click.util.HtmlStringBuffer

org.apache.click.util.HtmlStringBuffer
Provides a HTML element StringBuffer for rendering, automatically escaping string values. HtmlStringBuffer is used by Click controls for HTML rendering.
For example the following code:
```
 public String toString() { HtmlStringBuffer buffer = new HtmlStringBuffer(); buffer.elementStart("input"); buffer.appendAttribute("type", "text"); buffer.appendAttribute("name", getName()); buffer.appendAttribute("value", getValue()); buffer.elementEnd(); return buffer.toString(); } 
```
Would render:
```
 <input type="text" name="address" value="23 Holt's Street"/> 
```
Synchronization
To improve performance in Click's thread safe environment this class does not synchronize append operations. Internally this class uses a character buffer adapted from the JDK 1.5 AbstractStringBuilder.

            map.put("selected", new Boolean(selectedValues.contains(option.getValue())));
            options.add(map);
        }


        // Add all attributes to buffer
        HtmlStringBuffer attributesBuffer = new HtmlStringBuffer();


        // Add the CSS class 'picklist' to buffer
        String cssClass = null;
        if (hasAttribute("class")) {
            cssClass = getAttribute("class");
            attributesBuffer.append("class=\"");
            if (cssClass != null) {
                // If class attribute exists, temporarily remove it
                setAttribute("class", null);


                attributesBuffer.append(cssClass).append(" ");
            }
            attributesBuffer.append("picklist\"");
        } else {
            attributesBuffer.appendAttribute("class", "picklist");
        }


        if (hasAttributes()) {
            attributesBuffer.appendAttributes(getAttributes());
        }


        // Restore class attribute
        if (cssClass != null) {
            setAttribute("class", cssClass);
        }


        Map model = new HashMap();


        model.put("id", getId());
        model.put("attributes", attributesBuffer.toString());
        model.put("name", getName());
        model.put("options", options);
        model.put("selectedLabel", selectedLabel);
        model.put("unselectedLabel", unselectedLabel);
        model.put("format", new Format());
